Aquaculture serve the culture of aquatic organisms, eg. B. water animals such as Fish, mollusks and crabs in natural or artificial We water ponds, rivers and in the sea. there can the existing body of water as a carrier of the plant and serve as a reservoir in parallel.

The Aquaculture technology has been strong in recent years is expanding and becoming the fastest growing Sector of the world food industry. In the course of globalization The markets have become the economic structures of Fish farms of local family businesses completed to international companies. Similar Like other marine uses, aquaculture has one Art crafts to a science, from regional farms with Improvements due to many years of engineering experience developed industrial production with high research potential. The transition from the catch industry to a cultural economy along with the intensification of production methods to a completely new industry. It is expected that the Aquaculture in the coming decades parts of the catch industry completely replace and thus new serious environmental problems, especially by global caged fish farming and very intensive Pond Monoculture.

The New industry demands large amounts of organic food and feed additives. Substantial residues of unused Food, metabolites and their degradation products remain with inevitable consequences in the water. Fish farming facilities need also place and engage in existing material and plankton transporting Flow regime. Therefore, the aquaculture industry often sweeping as a major environmental polluter and irritant considered in the aquatic environment. That should be through a whole series of technical improvements, management systems and government Intervention to reduce the environmental impact and the interaction counteract the natural environment. meanwhile Numerous computer systems control the effluents and waste outlets of fish farms through interpolation of material balances and dynamic Flow models. There are z. Eg estimates the sinking rates of feed residues and metabolic products to predict the impact of the aquaculture operation on the benthic ecosystem made and improved the management of feeding methods. Also help guidelines for a gentle operating practice of aquaculture facilities to the fish farmers in detection and solution of environmental problems. Aquaculture companies improve their image in public appropriate quality assurance programs. About that In addition, a more efficient operating practice leads to an increase the generation capacity of this industry and its reduction self-pollution within cages.

STATE OF THE ART

morning In-pond flow channels in the form of vertical, hard-shelled Swimming tanks have been used since the 1970s to provide youthful ones Salmon (Oncorhynchus spp.) To cultivate. They are with sea bags comparable and consist of three primary components: A waterproof plastic wrapper on a swim collar was drained through a circular sieve. A waste reduction was not intended. The water level was determined by the density of the Water regulated within a hydraulic pressure tube. The vertical flow channel was through a pump and a community system for oxygen management. In some breeding systems a stocking density of 20 kg / m3 was recorded in a container with a volume of 23 m3 practiced. Prerequisite for this is a 0.8 to 1.3-fold water exchange per Hour.

In the 1980s, a vertical hard-shell aquaculture system was introduced for rainbow trout (Oncorhynchus mykiss) and carp (Cyprinus carpio) in eastern Germany. The fish cultures were protected against predatory organisms and free-living fish stocks against the escape of cultivated fish. The plant used the ambient water for waste separation, for the working process and as a biological filter. Within a floating body or a boat round GRP tanks with central flat connections were combined with a lamella clarifier. The collected waste should be processed as an organic fertilizer in agriculture become. An airlift system, a low-power hydropneumatic pump for circulating water between the pond and the plant, was used to improve oxygenation. It used the water resources of different depths depending on the quality of the parameters. The proposed aquaculture system was designed to increase stocking densities 3 to 5 times greater than the use of cages and improve work productivity. Intended for use in calm surface waters especially for operation in large lakes or protected coastal areas, the technology was sensitive to waves and was never used in commercial aquaculture.

One horizontal in-pond studied at Auburn University Flow channel used for the production of the channel catfish (Ictalurus punctatus) was constructed of treated plywood. The flow channel was constructed as a rectangular box and suspended between the sections of a floating pier. The flow was through a number at the top of the flow channel airlift pumps. The cultures were against intrusion from predatory insects or fish or the escape of cultivated fish protected with a net on the airlift outlets. In addition to the optimized hydropneumatic design Pump system was the flow of water at low oxygen content flooded with air in the pond. The wastes were from the Crops supported by a 4% soil tilt and the flow is separated. A two-stage filter system collected and removed settled residues. A first Step was in front of the drain into the pond right on the cultural area in Form of a funnel provided. With another airlift pump the concentrated residues became continuous promoted to the second collector outside the pond. This slowly flowing solid collector served for settling and Store until emptying. His drain was directed into the pond. The garbage disposal system was able to capture fish waste from entry keep away in the pond, but his performance was for unsatisfactory. A stocking density of 236 fish / m3 was with usual economically efficient production systems comparable. Caused by disease problems in the pond was the Yield with 52.2 kg / m3 catfish after a 124-day culture period lower than expected. During the further development were different sizes and materials with all advantages and disadvantages tested. An essential factor for the operation was the ability in any Waters to swim if there is a dock or a pier as a working platform. It was at a stable water level also possible to anchor the system at the bottom of the pond. Of the Waste collector was improved by tubular settlers. It a stocking density of catfish of 215 kg / m3 was achieved. The system was flow controlled and achieved a water exchange rate of 15 per hour, but only important for salmon and trout is. Some versions of the system were built without waste bin, to better control fish production and lower To achieve escape.

Mariculture Systems Corporation developed a cylindrical vertical hard-shell floating tank made of polypropylene, polyethylene and GRP called SARGO. The conical tube bottom and the Waste collection methods were comparable to sea bag systems. All Processes were controlled by self-developed software. The inflow could despite high flow rate be treated with ozone or technical oxygen. The work platform could with different modern equipments for Aquaculture facilities are stocked. One for approx. one year tested prototype (1996-1997) existed from a single boiler with a volume of 875 m3. stocking from 29.6 kg / m3 to 45 kg / m3 were tested. A big system with 2000 m3 has never been constructed.

One another horizontal in-pond flow channel, which consists of two rectangular containers with a productive volume of each 8.5 m3 was firmly installed in a pond and was Called in-pond circulation system. The system was completely waste-free for the controlled production of hybrid rock bass designed. The pond itself served as a biological purification stage for the system drain. As with previous systems the water is moved through a hydropneumatic pump. Everyone Container had a power requirement of 1.1 KW. While the study was the average weight of the developed fish fry 0.44 g. The survival rate up to an average Fish weight of 46.4 g reached 97.8%. With a feed conversion rate from 1.16, the average yield in the container was at 51.2 kg / m3. Experiments with different stocking densities showed same growth and feed conversion rates. Up to a height of 59.1 kg / m3 at the end of the breeding season the stocking density was none Influence on the increase of the individual body weight. Obviously, the hybrid rock perch can succeed even at high stocking densities be bred. A similar Australian Flow Float Tank is available from Tamco P / L.

The Semi-Intensive Floating Tank System (SIFTS), a commercial vertical aquaculture throughflow system in the Australian salty groundwater evaporation basins, was constructed for the rainbow trout (Oncorhynchus mykiss), the Mulloway (Argyrosomus japonicus) and the glass bass (Lates celcarifer). The vertical tank in the design of the Marikultursyste A special application for desert aquaculture in the salty coastal areas is equipped with a particle collector that removes approximately 95% of the settleable waste. The nutrient sludge with a dry matter content of 5-10% reaches a total amount of dry material of 5 tons per ha and year. It contains 144 kg of nitrogen and 153 kg of phosphorus per ha and year. In many experiments, in-pond bioremediation techniques have been integrated to better manage microalgae blooms. The benefits of bacterial water treatment, promoted by a heterotrophic "biofloc" community, are being researched at the Bribie Island Aquaculture Research Center (BIARC). A stable level of oxygen saturation and water quality in the cultural area is guaranteed by an airlift system. This is essential because leakage of dissolved nutrients in the pond will result in micro and macroalgae blooms with unstable oxygen levels.

From the US Pat. No. 6,443,100 B1 is a waste-depositing system for fish cages is known, which separates by mechanical and fluidic means fish waste from the culture water of aquaculture and feeds a discharge opening. The thus pre-cleaned water is removed from the system and further used in a manner not further described or disposed of.

From the US 6,192,833 B1 For example, there is known a partitioned aquaculture system comprising an algae growth channel for growing algae to regulate oxygen concentration and fish feed, one or more forced flow water channels for culture of fish or other aquatic animals, and a coarse waste collection center. It is a plant whose environment is not further specified. The transmitted water whose environment is not further specified. The water passed through is used to dispose of finer waste and soluble pollutants, a filter system is not provided. A sensor system records chemical parameters of the culture water and its temperature.

From the DE 10 2006 020 128 A1 , from which the present patent application proceeds as the closest prior art, a new version of the horizontal in-pond flow channels with solid waste management is known with a water-based ecological aquaculture plant. Floor slopes of 15% in individual areas of the culture tanks support the flow and move waste to the collection point. Deposited particles can be removed during the culture times and also during the harvesting process. The use of the plastic film fabricated with its own floating work platform is possible wherever the water is deep enough and moderate flow conditions prevail. Water is pumped with a hydropneumatic system and changed several times an hour. The stocking density depends, among other things, on the capacity of the pump system, the quality of the ambient water and the cultivated nature. The system has a water delivery system that can regulate the temperature through heating or cooling, the oxygen content through technical gasification and the flow of incoming water through pumps and valves. However, the type and arrangement of the floating and buoyancy tanks make the aquiferous aquaculture facility sensitive to rolling and waves, which can disturb the culture organisms. Heating and cooling make the operation of energy intensive. The filter system can not retain fine suspended matter and dissolved pollutants, contaminated water is released into the surrounding water body.

TASK

in the The state of the art describes in-pond aquaculture plants, the surrounding water as a loadable reservoir for the Include supply of fresh and the removal of contaminated culture water. By the increasing intensification of the operation and the size of in-pond aquaculture facilities, the fauna and flora in the surrounding However, water bodies have changed permanently. The task for the present invention, therefore, is a In-pond aquaculture facility ready for culture of aquatic organisms which does not pollute the aquatic environment and, where appropriate, in addition, the ambient water and its natural organic trimming ecologically gentle and economical includes synergetic targeted. The SOLUTION for the object is to be taken from the main claim. Advantageous developments are shown in the subclaims and below explained in more detail in connection with the invention.

With the aquaculture plant according to the invention for culture of aquatic organisms are water animals such as fish, molluscs and crayfish in a natural or artificial Waters are bred, with the ambient water as a carrier of the plant and used as a reservoir. The free and the cultured organisms should not be mutually exclusive adversely affect z. As by parasites, diseases, aggression or genetic engineering. You will therefore be at least one over the Ambient water lockable culture container kept physically separate from each other and only in case of need the inflow or outflow water connected.

This is cleaned via a filter system that is both mechanical-physical as well as biological units for the removal of solids and having dissolved substances. The treatment of feed shares plays along with a fish food return system a major role in determining the quality and the Environmental impact of sewage from fish and crustacean farms. With regard to the health of the natural fish stock reduces the vaccination of cage fish and the breeding of resistant species together with optimized hygiene management the administration rates of drugs, hence the outflow of Chemicals and eventually improves the environmental impact. To avoid the use of conventional medicines can symbiotic species such. B. Golden bream (Ctenolabrus rupestris) or flatworms (Udonella spec.) reliable for Protecting salmonids from parasites contribute to the infestation with sea lice (Caligus elongates, Lepeophtheirus salmonis) control effectively. So fish health is an important economic one Factor with ecological benefits.

at the implementation of traditional methods on aquaculture The reuse of water resources is also important for the reduction of pollutant emissions, the waste disposal and food recycling. Currently, pond water reuse systems and integrated cultures studied and evaluated. Pond systems can be combined into a network of breeding, settlement, water coarse and fine cleaning, phosphorus and nitrogen reduction. Ideally Each area with its own product achieves an economical one Result. For example, dissolved nutrients in aquaculture plants of microbes, algae or plants, or intermediates processed into fertilizers in agriculture. Feeding to invertebrates or higher Vertebrate converts waste into valuable products or Food components. The environmental benefit of waste recycling So is also a huge economic gain. In times of rising prices for fishmeal based Feed aquaculture can take advantage of new sources of protein. A main advantage of the mentioned innovations is the control over the fish production. The surrounding lake or pond serves as Reservoir and workstation for the control of parameters in the breeding area. The reservoir is part of a complex system from various areas with different functions and conditions. Further Advantages of this technique can also be higher stocking density, precise disease control, taste control, Collection and reduction of fish waste as well efficient process management during production.

The Aquaculture plant according to the invention with a supply system for culture water with a filter system with at least one Separating sieve and a sedimenter, can be without supply from the and discharge be circulated to the ambient water, the filter system additional filter modules for cleaning the circulating Culture water of suspended solids, solutes and Reduction of carbon dioxide and nitrates has. The water of the Culture container is floating over different or diving filter systems cleaned environmentally neutral. The filter system integrates mechanical-physical and biological filter modules for removal of solids of all fineness and dissolved Substances. The system aims at ecologically sound and resource-saving solutions. The inventive Aquaculture plant is a combined working and buoyancy platform with filter modules and culture containers and provides a floating Water-based circulation, clarification and flow system represents.

A first advantageous development of in-pond aquaculture after of the invention results when the filter system as floating, arranged separately to the culture container and with this movably connected filter block is formed. The filter system is except for an optional coarse or lamellar filter of the culture container separately in a deployable in the platform floating Filter block summarized, either from a subdivided Block or can be composed of individual modules. It follows the possibility of variants of the system Need to combine and so the implementation of various Facilitate production methods.

A further advantageous development of the in-pond aquaculture plant According to the invention, when the filter block has a stable, has treadproof cover and thus part of the work platform is. The filter block is a stand-alone, with the culture container flexibly connected and non-submerged module. In this respect offers It is about to cover him walkable, without opening opportunities to disregard the operation of the filter modules.

Further developments of the aquaculture plant according to the invention arise when, on the one hand, the filter block is associated with two culture vessels and connected thereto, which are respectively arranged on the right and left of its longitudinal sides and on the other hand a plurality of filter blocks with their associated culture tanks can be arranged to aquaculture facilities on an industrial scale. If you use a combination of several culture containers, you can keep the efficiency of the filter system permanently at a maximum by using different stocking densities, species or organism sizes. because in the filter, the drainage rates coupled several basins and thus the load can be averaged and stable adjusted. A Netzgehegeartiger use in the culture container allows the parallel cultivation of different sizes already in a culture vessel and results in a special management which contributes to the genanten Besatzkonzept and shortens the harvest intervals and thereby reduces unwanted fluctuations in the filter load.

A further advantageous embodiment of the invention Aquaculture plant arises when the filter block mechanically physical modules in the form of lamellar filters or according to the decantation principle. There is a mechanical / physical filtering in the input for Solids via different lamellar filter inserts to be calculated or simple decantation, when in a vessel with low flow rate suspended solids and the clarified Water drains off at the top. This process is similar decanting wine from the bottle into a carafe, in which Carefully poured off is tartar and depot in the bottle withhold.

A another development of the aquaculture plant according to the invention arises when the filter block biological modules as purification stages has the principle of moving fluid bed. It will be surface-enlarged filter substrates over Outlets or injectors moved and the settling on Bacteria supplied with oxygen. Preference is given to Teflon-coated Vents with hemispherical plastic substrates combined. Since these have only a low structural height outside they tend less to entanglement unlike other systems and the preferred vents through a nano-coated Surface less for blockage with biological growth. These energy-saving combination is particularly suitable in the use of In-pond facilities. This can more with the same compressed air power Filter substrate activated per filter volume and to clean the Used drainage water. Preference is given as possible large fillers (30 mm +) thus reducing biofouling also large mesh sizes of the sieves or flow openings can be chosen between the individual filter departments. Since the system is supplied with the ambient water, it can be in the Contrary to land-based investments the broad biodiversity of the water in the biofilter. On the substrates Settle bacteria, protozoa and other microorganisms up to a few millimeters in size. By the water movement these are sheared off evenly from the substrates which positively influences the degradation of nitrogen, as the bacterial layer can be stabilized in an effective thickness. The severed biological material and the free-floating rotators of the biofilter can then be used as food for fish fry become.

The Aquaculture plant according to the invention will be advantageous if the supply system for culture water a mixing chamber with a purified water inlet from the filter block, an inlet into the filter block, and at least one inlet and one outlet to the ambient water as well as connecting pipes has to the associated containers. about a mixing chamber at the end of the filter block becomes the purified water returned to the culture tank. Thus, the aquaculture plant according to the invention is basically a circulatory function available. It can be filtered or fresh ambient water. The mixing different waters also allows customization concepts. The purified water can also be transferred to the water and replaced by ambient water through this mixing chamber become. Thus, the system also becomes a flow-through wastewater treatment plant.

Further the aquaculture plant according to the invention can be advantageous be further developed when the inlets and outlets the mixing chamber infinitely controllable valves for the production of any Have mixed states. That way the plant can driven in the circulation or by mixing in warmer or colder water from different sources Temperature and ingredients and the effluent of culture water in the ambient water to the different needs of different Modes adapted.

A further advantageous development of the aquaculture plant according to the invention results when the connecting pipes have an overcapacity of at least 10% to 40% of the pipe cross-section with respect to their calculated flow in order to compensate for biofouling effects. The use of a non-toxic antifouling coating for the outer surfaces and the discharge line of the culture container is known. This coating must be free of biocides within the plant, so in contact with the culture water to avoid interference with the bioreactors. Even on areas bordering on ambient water, environmentally friendly coatings are to be preferred for larger bodies of water and unavoidable in small waters. A biofouling concept provides for adaptation to the threat of biological uptake by the resident organisms on site in the culture tank and its tributaries. To prevent biofouling in tube sections, these were therefore expanded by the expected annual growth measure and obtained in terms of their calculated flow overcapacity of at least 10% limnic at risk of various mosquito larvae, 20% in anticipation of limnic mussel species and in saltwater by at least 30 % of pipe cross section. In addition, they are constructed as short as possible, which is facilitated by the parallel position of culture and filter unit.

additional advantageous developments of the invention Aquaculture plant arise, if on the one hand the inlet for the culture tank an inflow pipe with turbulence generator and on the other hand the turbulence generator from an injector nozzle on Inlet pipe or an airlift pump is formed. A turbulence generator z. B. in the form of an injector nozzle on the inlet pipe or Using the airlift principle creates turbulent flows in the culture container inlet and also reduce the growth.

The Floating system of the aquaculture plant according to the invention with horizontally arranged on the periphery, tubular, air-filled, non-floodable and with the culture container movably connected, through solid covers as a walk-in work platform trained swimming vessels learns others advantageous developments, if on the one hand additional, air-filled, non-floodable and with the rest having associated floating containers that vertically in the ambient water are arranged and shaped like buoys and on the other hand only on the Front side of the culture container arranged horizontally, having a tubular floating container, the with the vertically arranged buoy-like swimming vessels is firmly connected and that as connections between and to the rest vertically arranged buoy-like floating tanks carrier structures are arranged. Horizontally arranged floats provide for the susceptibility of the system to wave influences, z. B. Whirling in all directions and punches. Vertical floats rest in depths that are largely closed to the waves and thus protect the system from swell. In places that because of the support of the culture container and systemic Lack of buoyancy bodies are particularly stressed can not do without a horizontal float become. The support structures can all be floating Firmly connect parts of the system and break-proof covers as parts of Wear work platform.

A further advantageous embodiment of the invention Aquaculture plant results when the buoyancy system with optional filled with water or air and with the culture container firmly connected, tubular buoyancy tank along the lower longitudinal edges and at the moving up and down the rear lower edge of the culture tank are arranged. The work platform is flooding and lowerable, with the flooding buoyancy as a basis for Serve running and support bars. Through the vertically arranged floating container is the attack surface for waves in the area the surface is reduced. This turns the rolling effect, as it occurs in certain circumstances, by the possible low horizontal and preferred vertical frame concept drastically reduced and animals with sensitivity to pressure fluctuations can also be cultivated. system damage by short waves is prevented. The work platform is flood- and lowerable up to a stabilizing volume fraction at the back of the system and a movable support tube on the plant front part. The Floods can be used as the basis for Serve running and support bars. The platform itself is so for the cultural unit to the buoyant body.

A additional advantageous development of the invention Aquaculture plant emerges when the temperature management system Heat exchanger, for which the housing of the culture tank and in the culture tank usable culture aids for aquatic organisms double-walled, structured inside and can be flowed through by a temperature-giving medium are executed. An integrated heat or Cooling technology for temperature management allows to adjust the culture conditions in certain ways. This leads to a special form of waste heat recovery in aquaculture. In combination with the surrounding waters and the outside air temperature can thus produce industrial waste heat be exploited. The communication of the water columns inside and outside the aquaculture facility in combination with the Temperature management of the culture container leads to a variety of mutually positively influencing cultural variants and system designs.

Another advantageous development of the aquaculture plant according to the invention results when the heat exchangers of the device for temperature control are designed as double-wall plates with internal lamination, preferably made of polyethylene. By integrating a controlled heat exchanger system waste heat z. B. from industry or cold water z. B. from wells to adjust the operating temperature can be used. This is achieved via a double wall system of the entire system or individual modules. In this case, double-web plates, preferably made of polyethylene, are used to construct the outer shell. Through the slats of the wall is thereby pumped in the event of waste heat waste heat-carrying liquids. The energy is then released to the water columns of Kulturtank or filter and also to the ambient water. In addition, heat-loving organisms can be cultivated in the container and the filter capacity can be increased. The energy transfer liquid is then returned to the heat source. It can be either freshwater, saltwater or any other liquid or gaseous medium. In the case of a cooling medium, the above applies accordingly. The web plates System is easy to clean and offers less attack surface for biofouling or aggressive saltwater. The medium contained in the web plate system can be transferred when lifting the culture tank in a storage tank so that the necessary buoyancy energy of the culture tank is reduced. If the medium is only fresh water, it can be discharged into the surrounding water when the buoyancy tanks are blown out. The wall panels can be designed symmetrically or asymmetrically in their wall thicknesses, which can be used to control directional or diffuse energy output or insulation. This increases the scope of the system and resources can be manipulated more targeted.

additional advantageous developments of the invention Aquaculture arise when, on the one hand, the facility for Temperature control inflows and outflows for relative to the ambient water of the culture tank Heated warmer water, eg. B. as industrial cooling water, and colder water, e.g. B. as deep or well water on the other hand, the inflows and outflows continuously controllable valves for producing any mixing conditions exhibit.

Further advantageous developments of the invention Aquaculture arise when, on the one hand, the facility for Temperature control Covers for the culture container and the filter block, and on the other hand the covers are simple or double-walled, fixed or flexible, folding, rolling, hinged or movable, made of transparent or opaque material and with or are performed without coatings. The energy flows of the overall system can be governed by many individual details, the capacities are expanded. Culture and filter unit are preferably with mobile as possible automatable Provided with covers which, depending on requirements, are single or double-walled, solid or foil-like, absorbing or emitting solar energy are designed. Flexible covers are changing the surface cover rolled, solid materials tilted, worked or moved. This changes the radiation and radiation, Convection and evaporation. Energy capacities will be so controllable. For certain climates, certain Combinations are chosen.

additional advantageous developments of the invention Aquaculture plant arise when, firstly, the establishment of Temperature control on the culture container extended Air vent with or without chimney to recover evaporation energy by condensation and second, the means for temperature control on the culture container a controllable air damper with or without forced Having air movement for the delivery of evaporation energy. A compressed air trigger with or without chimney allows in case of low energy input the recovery of the evaporation energy during however, an opening option with additional Air movement the delivery of the evaporation energy many times over elevated. About the regulation of evaporation over exchangeable air volumes and the type of ventilation, over Convection and its direction, via irradiation as well their reflection and fresh water with variable inlet temperature It can be used in a wide range of climatic and broad applications to be cooled energy capacity and the Selection of different cultural candidates to be expanded. While previously temperature-controlling plants either land-based built in halls and flow systems or net enclosure in the heated Range of rivers were installed at power plants, is the aquaculture plant according to the invention in the Able to specifically target energy capacities in the outdoor sector exploit and extreme variations of outdoor climate and the Supply of heat capacities to control and to Buffers. This is done via the energy-exchanging shell of the culture container diffused or directed with a selected Medium, through a system of covers, flaps, compressed air, Blowers and chimney on the container surfaces, over Water exchange rates and the interaction of waters and plant. The filter concept of sediment and filter block must through his direct contact with the microorganisms of the water adapted to the biology of the system of surrounding waters and culture containers be. On the one hand, the bioreaction reaches its maximum workload extremely quickly, However, it leads to excessive growth with different Organisms also quickly become malfunctioning. For filter optimization are therefore the preferred substrates as the usual semicircular Plastic filler or coated vent just as necessary for cross-sections adapted to biofouling, mutually alternating pressurization of the outlets, flow plates and avoid any interfering edges in the bioreactor. Also the mix of water from different culture tanks and or additional external water at a permanent production optimum is part of a problem solution.

Furthermore, there is still an advantageous development of the in-pond Aqukulturanlage according to the invention, when the temperature management system has double-walled and can be flowed through by a temperature-generating medium heat exchanger as usable in the culture container culture aids for aquatic organisms. The cultural aids is primarily a insert module of inserts, which enlarge the floor areas or provide coverage and privacy, resulting in economic breeding of z. B. shrimp or flatfish makes sense. Several preferably similar in oblique angle Plates or profiles arranged in the culture container bottom provide the culture organisms with space and cover, an inlet pipe for inlet water mounted at the beginning of the plate provides oxygen and flow and makes sense, especially in hot water operation, since the necessary oxygen demand of the animals can be covered between the plates and feaces be rinsed off. These culture aids can also be designed as heat exchangers in order to provide heat directly to the cultures. The whole module can be inserted or replaced by a simple suspension. Above all, it is to be regarded as species-specific, its development can only be promoted by practical application, but thus increases the species justice of the attitude and the economy of the plant. For shrimp farming, the insertion compartments are offset in a preferred manner at the flow inlet such that a feeding from above is always possible. Furthermore, there are additional staggered openings in the compartments so that waste can be rinsed down.

Finally There is still another advantageous development of the in-pond Aqukulturanlage according to the invention, when the buoyancy system, the double-walled housing or the sheath of the culture container and / or the housing or the jacket of the filter system as flooding and blow-out Buoyant body uses, and this in addition controllable flood valves and blow-off valves or an evacuation pump exhibit. The because of the temperature management anyway existing double-walled Containers around the culture tank and the filter block can for the short period of fishing and any necessary cleaning operations advantageous at the same time be used as a buoyant body. To They can be used along the edges of the culture container and the filter block existing buoyant either support or even replace.

In The further description will be to illustrate the versatile Possible applications Four exemplary operating examples the aquaculture plant described according to the invention. It deals is a brackish water use in the Mainly shrimp stretched and fattened continue to be a smoltification plant in freshwater salmon (Parr) accustomed to the salt water and pre-stretched to smolts can, a breeding and stretching plant in fresh water for the rearing of fish larvae, z. Zander or carp and ultimately around a mast plant for shrimp in the high-saline desert aquaculture.

The first example describes the culture of shrimp with waste heat reduction and use of brackish water sources. The plant can be used for this purpose in pond systems, which offer the possibility in their nature and size in case of overheating heat capacities to dissipate or save in the opposite case. The heat capacity is transferred either via the culture tank walls in the system and or via separate heat exchanger in the pond or in the system. The design is dependent on the available heat capacity, the pond and culture container size and the sensitivity of the Shrimpsart to be cultivated. Ideally, the existing heat is sufficient throughout the year in cold or temperate zones for aquaculture of large Speiseshrimps z. B. the genus Litopenaeus or Macrobrachium. The plant preferably consists of culture container pairings, each with a central filter block and the work platform. The pond can be designed as a concrete or natural pond. The water supply from brackish water sources in combination with the evaporation and an additional fresh water inflow allows for special cases on the one hand a precise adjustment of salinity and water quality, on the other hand a manipulation of the water temperature, which is regulated by the heat exchangers up and by the inflow and evaporation down. The use of waste heat saves additional energy for cooling capacity. The system's covering system in combination with waste heat, heat exchanger, inflow, evaporation and convection gives this type of plant a temperature concept and thus synergy effects for the holder of the waste heat and the holder for the cultural animals. Thus, an economical, decentralized aquaculture concept can be carried out, in which several small waste heat holders of several decentralized waste heat ponds are equipped with small and medium-sized aquaculture plants. Plants under certain production sizes are often uneconomic. By using the waste heat, saving of cooling power with the use of other products but here profitability can be achieved, especially if the aquaculture is understood as a service, with several companies use decentralized aquaculture as cooling, which then centrally operated by a company, be serviced and marketed. In addition, several companies can optimize the overall system by special composition by z. B. a carnivore-herbivore concept or feed optimization concept is realized in which egg-eating species are fattened in the culture pool and thereby utilize about 30% of the fed nitrogen and phosphorus compounds. The rest is accounted for as sediment or as a dissolved nutrient. Biofiltration converts the toxic dissolved nitrogen compounds into harmless nitrates, which can be released into the pond and additionally allow a culture of different microalgae or macroalgae. These can either be harvested and recycled outside or the pond becomes extensive, So low with plants or plankton-eating genera such. As mullets (Mugil, Chelon) or milk fish (Chanos) occupied. In freshwater plants carp species from different genera such. As cyprinus or ctenopharyngodon be used. Thus, dissolved nutrients are bound in another product and increases the efficiency and environmental impact of the plant. The resulting sediment is stripped or collected in the mechanical / physical stage and further processed in a waste utilization concept. The sediments can be further converted into energy and fertilizers in a biogas plant, or fed to waste-eaters at an animal feed production or fodder farm, and converted back into protein. As breeding candidates are preferably different groups of waste recyclers such. B. Sediment-eating worms, crabs or molluscs. For safety reasons, the farmed food animals can only be fed directly to species from which the sediment does not originate or are processed into artificial feed in a feed mill and thus also fed to animals from which the sediment was collected. Due to the special combined stocking concept of the system a multiple optimization is achieved. Fanned inlay modules increase the surface of the crop and provide privacy for the shrimp. These tend to be too close to cannibalism and cause each other in close stance damage. Above all, the number of adult animals is limited by the existing floor area. The compartments thus increase the surface area per culture water volume and thus increase the stocking density per cubic meter of the plant. Incidentally, this surface also increases the turnover of nitrogen by nitrifying bacteria. When pond water is mixed with recirculating water, the microalgae produced in the pond reduce the depth of view in the cultural area, which further enhances the shrimp culture, as they see each other less and thus get less stress. A further improvement of the stocking density is achieved by attaching culture additives, which can be attached like a net cage in the culture tank directly at the inlet of the mixing chamber. In it post larvae of the shrimp can be pre-stretched. With a culture period of, for example, three months, four harvests per year are possible. If you operate two main culture containers with two batches, you get 8 crops per year and the filter has to compensate for strong fluctuations with each harvesting process. However, if you operate one of the containers with the generation that is almost ready for harvest, and the second with medium sized animals and post larvae hooked into the net enclosure, you can continue to fatten the medium batch after the harvest of the finished mast as the largest animals, the stretched ones But leave the post larvae in the harvested container and grow them into the medium sized batch. The cultural use is now relocated to the new medium-sized specimens and newly occupied with larvae. This results in twelve crops per year with a more uniform filter load due to the stocking concept.

The second example describes a smoltification plant without cultural inserts, in the freshwater cultivated with salmon become accustomed to an adaptation concept to the marine environment. Here less the temperature but rather the salinity is important. The system consists of the usual modules, preferably but with reduced effort in the area of temperature management. In individual cases, the heat exchange capacity of the Case can be used to better by low heat input To achieve growth rates. Important in this type of construction is also the Protection from predators, d. H. The plant is less for isolation as more needed to separate the habitats. This eliminates the need for insulating covers. It suffice nets or simple lids. The juvenile fish have to especially protected against parasites, eg. B. in front of salmon lice. So that the salinity adjusted is an inflow of saltwater and freshwater necessary. The former takes place through the surrounding environment, the others can be supplied with a separate line. The water with the highest risk of infection can if necessary with UV or ozone disinfection. By slow Adjustment of salinity and lower parasite load is reduces the mortality of smolts. Because of the circulation the culture water is recycled, the cost of fresh water supply be reduced. Also in this design, the waste utilization concept for Sediments are used.

The third example describes a limnic hatchery or Hatchery plant, which is similar in the basic plan of the shrimp plant, but requires a nesting concept with microorganisms of the bioreactor and pond plankton with a flow through a light trap. In combination with the mixing chamber, the plankter trapped in the forerunner are mixed with the organisms of the bioreactor, so that feeding into the culture container simultaneously feeds the brood. Thus, a continuous feeding is achieved in addition to a possible additional feeding. The danger of cannibalism in breeding can thus be reduced. Mesh grids in front of the inlets prevent the penetration of predators, covers or net curtains prevent the breeding robbery by birds such. B. Cormorants. At the actual inlet to the mixing chamber a light source with sieve is attached to catch the Plankter here. Lured organisms are sucked in via the influx, but the sieves can not pass too large organisms and stay in the surrounding water. Marin can also operate this plant form, z. In fjords or near-shore saltwater ponds. Also in this embodiment, the waste utilization concept can be applied. As a feed animal breeding the preferred culture in marine plants here is the cultivation of copepods of the group Harpacticoida, limnic is a culture of native or Japanese water fleas z. B. the genus Molina attached. The concept of meat and herbivore is preferably applied in closed waters, eg. As pond systems or smaller lakes without open drain because open systems can not be trivial regulated. Inserts to increase the stocking densities are not provided in the preferred system in Brütlingen, special feeders can be attached as in all versions.

The fourth example finally describes a for the desert aquaculture suitable shaded plant type. The system allows for a fish concept without heat damage, because the culture is quickly fished by the lifting mechanism and the water level of the water can not be lowered must become. The animals will continue to be supplied with fresh water. The plant corresponds to the former shrimp plant, the temperature concept however, in contrast to cooling over modified the energy exchanging outer shell. The heated water can be used elsewhere. This type of plant makes sense in widths with strong positive temperature peaks. Even on hot days, a mast is still possible. All other concepts described above may be used Find. Central industrial aquaculture is also possible.

The Figures are schematic representations and not to scale and only provide examples of possible embodiments dar. In the figure descriptions mentioned but in the associated Figures not shown are the preceding or to take the following figures.

1 shows a basic design of the in-pond aquaculture plant 01 in the circulation mode in plan view. In a frame system 02 from flooding floating tanks 03 and floatable buoyancy tanks 04 are the culture tanks 05 and the filter block 06 integrated. The left culture container 05 is here in the raised state, the buoyancy tank 04 are blown out. The right culture tank 05 is lowered, the buoyancy tank 04 are flooded. The filter block 06 and the culture containers 05 are arranged in parallel to keep the connections as short as possible. The subdivision of the filter block 06 is adapted to the conditions of the operating concept. The system of floating tanks 03 is largely by vertical, buoy-like floating tank 07 realized that are tapered down and take over there the main buoyancy. Thus, the use of standard, low-cost buoys is possible. In addition, shaft movements are compensated and the loads of the frame system 02 and the culture organisms reduced. In the back area 08 are the vertical floating tanks 07 with straps 09 associated with little or no buoyancy. In the front area 10 becomes the frame system 02 through horizontal, tubular floating tanks 11 reinforced with strong buoyancy to the culture vessel 05 to stabilize in the raised state.

In the circulating mode of the in-pond aquaculture facility 01 is the bulkhead 13 in the partition 14 geö opened. The culture water passes through the culture tank 05 through a sieve 15 in an integrated sedimentation stage 16 to get where solid particles are physically-mechanically stripped. Here, depending on the expected degree of contamination, the flow rates and the particle size z. B. with a combination of inclined tubes sediment package or only with water calming without aids. In the case of heavy coarse-grained contamination with a slow flow velocity, no lamellae are required; less load with the smallest particles requires narrow tubes or flat lamellas. The flow mode of the in-pond aquaculture facility 01 comes about over the bulkhead 12 in the culture tank enters the ambient water through the fresh water. The bulkhead 13 in the partition 14 is closed in this operating mode.

2 shows a full equipment of the in-pond aquaculture facility 01 , here z. B. for shrimp farming. The pipes 17 serve for pumping out waste 52 , The pumped waste 52 , z. B. as sewage sludge 41 , are preferably further processed according to a utilization concept. The culture container 05 is divided into a flat zone 35 and a deep zone 18 , In the flat zone 35 can be fed lossless, in the deep zone 18 the bottom sediments become a sieve 15 directed. aerator 19 support the flow pattern and increase the oxygen concentration in the culture water. In the culture container 05 are optional net enclosure 20 and insert modules 21 attached to improve the stocking density. A system of suspensions 22 and locks 23 creates connections between the frame system 02 and the culture containers 05 and the filter block 06 , also in different positions of culture containers 05 , That from the sedimentation stage 16 Discharged culture water is used in the biological modules 38 biologically cleaned. An additional sedimentation stage 24 is possible depending on the load. Is a culture container 05 raised (left side of the 2 ), the connecting pipe must be 25 between filter block 06 and culture container 05 so far withdrawn that the culture container 05 can be easily raised. The pre-purified culture water then passes over the shortest possible connecting pipe 25 in the filter block 06 , To a culture container 05 To raise, the contained water must have closable outlets 26 be dismissed with adjusted sieve sizes. In addition, they need the culture container 05 framing floatable buoyancy tank 04 be blown out with compressed air or pumped out.

3 shows the work platform 27 the in-pond aquaculture facility 01 on the filter block 06 , The buoyancy tanks 04 at the culture containers 05 can with catwalks 28 be equipped for better accessibility. Not shown openings in the work platform 27 for reaching functional parts of the filter block 06 are required.

4 shows a fully equipped in-pond aquaculture facility 01 in longitudinal section. The pictured culture container 05 is laid flat here for floor dwellers. He is with a heat exchanger 29 , a cover 30 and cultural aids 31 equipped for aquatic organisms. The main components of the temperature control system are the heat introducing heat exchangers 29 which can be filled and emptied via valves not shown here, the chimney 32 and the louvers 33 , These are either manually operated or automated, here via a lifting cylinder 34 , Shown is the flow of the culture water (solid line) and the compressed air (broken line). Compressed air from the aerators 19 is with closed air dampers 33 through the chimney 32 given off, the energy recovered by condensation. With open air dampers 33 Energy is released via escaping water vapor. This can, together with a regulated heat input through the heat exchanger 29 the temperature control done. The flow of the culture water is through the compressed air from the aerators 19 with influences and results together with the inlet an optimal flow regime.

5 shows operating positions of the in-pond aquaculture facility 01 in longitudinal section. The flooded floats 04 keep the culture container 05 in the lower position. He is in the back area 08 with a stop 36 on ( 5A ). When blowing out the buoyancy bodies 04 becomes the culture container 05 by their buoyancy until stop the lock 37 on the cover 35 the vertical floating tank 03 pivoted to the upper position. The water passes through the outflow openings 26 out, the organisms are gathering in the front area 10 of the culture tank 05 and can be edited ( 5B ). For better control of the buoyancy, the floodable buoyancy body 04 be divided into individual chambers. 5C shows the course of the culture water in the raised position. The organisms are further supplied with culture water, the sediment of the integrated sedimentation stage 16 can be rinsed. Whether the resulting rinse water is collected or released into the surrounding water depends on the operating mode.

6 shows a flow model of the filter block 06 the in-pond aquaculture facility 01 in cross section. The filter block shown here 06 as it can be used in shrimp farming, has two biological modules 38 and an intermediate sedimentation 39 on. The soils are for better concentration of sewage sludge with slopes 40 Mistake. The sewage sludge 41 can be via suction pipes 42 be removed. The heat exchanger 29 transfers heat into the filter block 06 , a system of covers 30 , Louvers 33 and chimneys 32 regulates the energy balance. Shown here is the flow path in the filter block 06 , pulled through the water flow, dashed the compressed air, spotted the condensate. That through the piping 43 incoming culture water is removed from the aerators with the help of compressed air 19 set in rotation, not shown here with bacteria-covered filter substrates of the first biological working module 38 carries out the biochemical reactions, remaining sediments settle as sewage sludge 41 or get into the intermediate sedimentation 39 where they can settle and be pumped out. The culture water continues to flow through the second biological module 38 into the mixing chamber 44 where it is preferably lifted by means of compressed air and into the culture tank 05 is transferred. The flow can be via valves 45 or bulkheads are controlled with sieves, but it just simply holes with diameters smaller than the filter substrates are sufficient. Controllable valves 45 increase the range of application of the in-pond aquaculture plant 01 and improve the temperature control. In order to avoid seizing the filter substrates is in each case a pair of aerators 19 attached to change the direction of rotation. Also the biological working modules 38 preferably have here not shown suction pipes for sediment. The integrated sedimentation stage 16 can be designed as a simple decanter or as a lamellar filter. If there is insufficient heat available, the covers remain 35 closed and the exhaust air escapes through the chimneys 32 where, as well as in possible exhaust condensers 46 that condenses water vapor and recovers energy. With excess heat capacity become the louvers 33 lifted as automatically as possible and high-energy steam escapes. This lowers the system temperature. If this is not enough, the in-pond aquaculture facility 01 be switched to the ambient water in the flow mode and continue to give off energy until reaching the optimum working temperature. The situation of the culture containers behaves similarly 05 , The calculation of the parameters of the filter block 06 This can also be done through common surface, bacterial and nitrogen loading relationships, but the strategy of low energy flows with longer residence times and slower flow rates should be taken into account as this will provide sedimentation optimization and less dissolved nutrients in the biologically operating modules 38 have to be reduced.

7 shows a large in-pond aquaculture facility 01 on an industrial scale. There are two culture containers each 05 around a filter block 06 arranged. Whether it's the Abfischbereiche 47 or, as shown here, the sedimentation areas 48 the culture container 05 at the central pier 49 centralized depends on the needs of the operator.

8th shows a model of a waste heat concept for an in-pond aquaculture plant 01 , The waste heat of an industrial plant 50 is via heat exchangers 29 to the culture container 05 the in-pond aquaculture facility 01 and delivered to the ambient water via convection. The heated culture and ambient water release water vapor (dotted lines) via their surfaces and heat of evaporation is dissipated. The in-pond aquaculture facility 01 itself is over louvers 33 and the control of ambient water supply and Kulturwasserabfuhr controllable. If necessary, the surrounding water can be adapted and preconfigured to the respective climate via earthworks or open spaces. This must be calculated using standard DIN formulations for wetlands.

9 shows a schematic operating concept of several in-pond aquaculture plants 01 , An additional optimized model is the concept of a consortium. Several waste heat producing industrial plants 50 They cool their plants by means of ambient water and in-pond aquaculture plants contained therein 01 , They are centrally managed by a service provider 51 who can also be a producer himself, operated, maintained and fished. Also, processing and marketing could be done by this service provider 51 be executed. This allows all in-pond aquaculture systems 01 concentrate on their core business, save cooling performance and participate in the marketing of organisms. Whether it is food or ornamental organisms is a matter of plant adaptation. All waste 52 are collected and z. B. in a biogas plant 53 utilizes which member can be in the consortium, as well as a partner who can handle this waste 52 can be refined by culture of feed organisms.

10 shows a substance utilization concept for an in-pond aquaculture plant 01 in the predominantly carnivore 54 be cultivated. Since these utilize only about 30% of the nitrogen and phosphates, nutrients remain as particles 55 and in dissolved form 56 back. The nutrient particles 55 are collected and either for recovery in a biogas plant 53 or to a service provider 51 transported the sewage sludge 41 uses for the culture of food animals, z. B. for tallitridism. These utilize some of the sewage sludge 41 and can be eaten again by carnivores. For safety against disease and parasite reimport feeding these organisms to species that do not belong to the Group belong which as suppliers of sewage sludge 41 or you prepare the feed animal or refine it in the production of artificial feed. The dissolved nutrients 56 be in the biological module 38 Oxidized by the bacterial culture to harmless nitrates and can be released into the ambient water, where they are absorbed by plants or algae, which in turn are eaten by higher culture organisms. Thus, the feed added at the beginning is utilized in three stages instead of one and gives a higher efficiency.

There all processes are closely related to each other, for the ongoing operation energy because of the very low pump height and feed reserves for the recovery of resources used effectively.

The 11 shows an in-pond aquaculture plant 01 with a buoyancy tank 04 designed heat exchanger 29 , To facilitate the lifting of the culture container 05 in the upper position through the buoyancy tanks 04 need the heat exchangers 29 be pumped out. It is therefore obvious, the volume of the heat exchanger 29 to support the buoyancy tanks 04 or replace them. The heat exchangers 29 can do this directly with the other buoyancy tanks 04 get connected.
