Device main claims.

The claimed aquaculture technique, i. the

Aquaculture facility and the associated

Cultivation procedures have several advantages

in terms of function, efficiency, environmental compatibility, sustainability and cost effectiveness.

The cost of feeding the reared aquatic creatures, especially fish, can be fed by feeding them into the aquaculture facility

Feed production and with the feed animals, in particular marine worms, are significantly reduced. The

Water consumption is also very low. It can be made a natural feeding circuit for the aquatic creatures. A use of other organic

Feed, in particular fishmeal, and of

Antibiotics can be omitted.

The food animals take on the one hand the particulate

Excrements of aquatic life forms or also

Other unresolved particles in the culture water and can thereby fulfill a filter function as feed animal filter. The feed animals can in turn with these particles as well as with algae, in particular microalgae from a

Algae reactor are fed. The aquaculture plant also has a filter for the dissolved in the culture water

Excretions of aquatic creatures. For this purpose, a plant filter is particularly suitable.

In a first aspect of the invention, an additional storage container for the culture water is arranged in the circulation of the culture water. The arrangement of this

additional reservoir allows an optimization of the rearing of aquatic life, food animals,

Plants and algae. The for the respective rearing

required amounts of culture water can be provided in sufficient size and separated from each other.

In addition, filter functions for the culture water or the filter circuit can be improved. particulate

Excretions of the aquatic organisms, especially fish, can be eaten by the animals and may possibly be deposited in their containers. dissolved

Excretions of the aquatic organisms, in particular fish, can be absorbed by the plants and may possibly be deposited in their containers. This multi-stage filtering process and the filter cycle with a feed animal filter and a plant filter can be optimized. In particular, the several

Filter functions or filter stages are separated from each other and independently controlled as needed.

The additional reservoir may have a buffer function for the culture water. The culture water supply to the various containers for the said rearing can be controlled as needed. The supply quantities to these containers and / or the cycles in the filter stages can be adjusted independently of each other. The additional reservoir allows in particular the formation of sub-circuits of the culture water. These can each be independently connected to the additional reservoir for the culture water and and can each be independently controlled. The cycle of

Culture water can be subdivided or supplemented by one or more sub-cycles.

The additional reservoir can be switched in the filter circuit between the feed animal filter and the plant filter. The two filters are not unmittebar coupled with each other. The coupling takes place indirectly via the additional reservoir. Here are the separately filtered subsets of the

Culture water together and mix.

Water pipe or the like comes. The fresh water is preferably only inorganic nutrients,

especially nutrient salts, electrolytes added. As a result, a pure nutrient solution can be formed. The fresh water can also be subjected to a particularly intensive filtering, in particular one

Reverse osmosis and / or ultra-filtration. the

Storage tank for the culture water can be preceded by one or more other storage tanks, with which the production and treatment of the culture water takes place. The water can be fresh or salt water.

According to a further independent aspect of the invention, a storage container for the nutrient solution is present. The invention aspect provides an aquaculture plant and a cultivation method for the rearing of aquatic organisms, especially fish, which has a

Algensuspension, and have a fluid connection with a container connecting the circuit for the culture water, wherein the aquaculture plant has an additional storage container for an optionally saline nutrient solution. An arranged in the culture water circuit additional reservoir for the culture water is advantageous, but not essential. The storage container for the nutrient solution is upstream, for example, the reservoir for the culture water. The nutrient solution consisting of fresh water is still not with excrements of the aquatic organisms

loaded. The reservoir for the nutrient solution can independently via a fluid connection with the

Plant container be connected.

As a result, a further sub-cycle and a self-inventive nutrient cycle for the plants can be formed.

Modular system can be provided. She can be in

Inland and far away from waters,

especially from the sea, set up and operated. The food production can be brought close to the consumers. In addition, the supply of non-local ethnic groups, such as refugees, with their usual food is made possible in the domestic. The effort for planning, installation and operation of the claimed, especially self-sufficient aquaculture plant can be minimized and simplified. The technical requirements for an operator of the aquaculture facility can also be reduced. The programmable controller relieves the operator. The aquaculture facility can be manufactured and marketed as a ready to use unit, eg in a franchise system.

In a further independent idea of the invention it is provided that the aquaculture plant a surrounding

Within the climate hall can be favorable climatic

Conditions for the rearing and possibly the offspring of animals and plants are created and kept constant. The preferred independent power supply and its own programmable controller are particularly advantageous for this purpose. The containers for the aforementioned rearing and the additional storage containers may be present individually or multiple times. The aforementioned different sub-circuits can each have their own

Have pump assembly.

The respective containers for the rearing of feed animals and plants can each be present several times. For the said container is recommended in each case a tower or cascade arrangement, the culture water the

various containers successively and flows through gravity in a cascade. The energy and pumping costs can be reduced. In addition, the containers can be stored space and cost saving on a shelf. This also facilitates the handling during the breeding care and the harvest as well as the maintenance.

In the culture container for the aquatic organisms and in the container for the rearing of feed animals preferably bottom-side substrate layers, in particular sand layers and / or gravel layers, are present. In the culture container, these substrate bottoms can accommodate a part of the feed animals, which can thereby live on in the usual environment and for the aquatic creatures, in particular ground fish or shrimp, form a longer-term and easily accessible food source. These containers can have an optimized fluid flow. This may have separate and / or optimized outlet openings for the culture water and / or the substrate. On the one hand, it enables a permanent and controlled flow of culture water. On the other hand, it allows a simple deduction of the substrate layer and the feed animals contained therein.

The claimed aquaculture plant also has the advantage of a particularly simple constructive and

cost-effective construction and operation. Here is the Arrangement of containers in stacks of advantage. The same applies to the preferred vertical structure of

Aquaculture plant and housing on a shelf.

When the aquaculture plant is operated with salt water, a flooding facility can simulate a sea-like environment with low and high tide for the animals and / or the plants. As a result, e.g. the environmental conditions for saltwater tolerant plants or halophytes are optimized. Alternatively or additionally, a continuous flow mode is possible. This particular has to be scalable

Plant production and an independent

Nutrient cycle with connection to the reservoir for a nutrient solution benefits.

Changing water levels with an intermittent

Filling and emptying the containers for food animals and / or plants and simulating ebb and flow have further advantages. The standing for a time water level leads to a calming and a longer residence time of the culture water, which is the inclusion of the particulate

Excretions and the algae by the feed animals

facilitates and favors. At low tide, the containers and in particular the local substrate can dry. The particulate excretions and algae may settle on or in the substrate, which is also beneficial for uptake by the feed animals. In addition, the changing water levels or water heights may result in additional filtering and rinsing effects in the substrate region, which are advantageous for the filter function.

Similar effects and advantages also exist with a plant filter.

The aquaculture plant (1) has a culture tank (6), in particular fish tank, with culture water (5) or

Process water for uptake of aquatic organisms (2). The culture water (5) may be salt water or fresh water. In the exemplary embodiment shown, salt water is preferred.

As illustrated in FIGS. 1 to 3, the aquaculture installation (1) can have, in addition to the culture tank (6), a container (22) for feed animals (3) and a container (23) for plants (4) and an algae reactor (9). The containers (6, 22, 23) and possibly the algae reactor (9) can each be present individually or multiply. The aquaculture plant (1) may further comprise a controller (44).

In a multiple arrangement of the container (22) for the rearing of food animals (3) is recommended a tower or

Cascade arrangement of the containers. The containers (23) for growing plants (4) may also have such a tower or cascade arrangement. The containers (22) and the containers (23) are in each case one above the other

arranged. You can do it in a stack directly above each other and with mutual contact and

Support be arranged. The subsequently explained FIGS. 9 to 17 show such an arrangement. Alternatively, the containers (22,23) in a tower or shelf directly above each other and at a mutual distance

be arranged. A cascade arrangement also includes a terrace arrangement in which the containers (22, 23) are respectively arranged one above the other and with a lateral spacing. The culture water (5) flows through the various

Container (22,23) in a cascade successively and by gravity The energy and pumping costs can be reduced. In addition, the container (22,23) can save space and cost on a shelf. This also facilitates the handling during the breeding care and the harvest as well as the maintenance.

The containers (6, 22, 23) and the algae reactor (9) can be hydraulically connected to one another via a respective fluid connection (12) in a water circuit (13) for the culture water or process water (5). FIGS. 1 to 3 show, by way of example, an arrangement of the containers (6, 22, 23) and of the algae reactor (9), as well as hydraulic circuit diagrams. The water cycle (13) of the culture water (5) can be self-contained. He may also have one or more sub-circuits (13a, 13 ', 13 ")

respectively .

Aquaculture plant (1). The arrangement of the containers (6,22,23) and the algae reactor (9) and the water cycle (13) for the culture water (5) can according to the

WO 2016/012489 Al be trained. FIG. 3 shows a second, modified variant of the aquaculture plant (1).

Both variants also show several more

Modifications of the aquaculture plant (1). Of the

Modifications described below may include one or more in any number and combination in the

Aquaculture plant (1) be present. The modifications each have an independent inventive meaning.

The modifications can each be combined with both variants of aquaculture plant (1) or in

Combination with another, possibly conventional Aquaculture plant (1) with the said arrangement of

Containers (6,22,23) and an algae reactor (9) and a water circuit (13) for the culture water (5) are used. In the first variant of Figure 1, the modifications are shown schematically. The second variant of Figure 3 shows a possible integration of the modifications in an aquaculture plant (1).

One modification concerns a progeny (2 ') of

aquatic organisms and / or offspring (3 ') of food animals. Another modification involves an arrangement of at least one additional one

Reservoirs (54,53) for culture water (5) or a nutrient solution (5 ') · A modification relates to an independent feeding circuit (15') for food animals (3). Another modification aims at a self-contained nutrient cycle (15 ") for plants

Training the aquaculture facility (1) is also a modification. One modification relates to the formation of the aquaculture plant (1) as a prefabricated and preferably modular construction and functional unit. As another

Modification is to be regarded as a climate hall (55) surrounding the aquaculture plant (1). Yet another modification is a scalable production of algae,

Food animals (3) and plants. Another modification relates to the natural rearing of marine worms in the aquaculture plant (1) for the production of hemoglobin.

The culture container (6) may have any suitable shape and may be made of a suitable material, e.g. Plastic or metal, wood or concrete. The culture container (6) may be open at the top. At the bottom of the

Culture container (6) may be a substrate layer (28), eg sand, a mixture of coarse-grained pearlite with sand, another sand-containing mixture or the like. are located. The inflow and outflow (33, 29) for the culture water (5) are at fluid connections (12), eg closed lines in Shape of pipes or hoses, connected. Alternatively, partially open lines or channels are possible.

In FIGS. 3, 6, 7 and 8, an example is shown

Embodiment of the culture container (6) and will be described below.

Alternatively, the culture container (6) may be designed as an open tank with a bottom drain (29), e.g. in the form of a siphon, and with an inlet (33) in the form of a

submerged inlet pipe with several, in

be formed different tank heights outlet openings. WO 2016/012489 A1 shows an example of such an embodiment.

The feed animals (3) are placed in the culture tank (6) and in the local culture water (5). You can float or swim there and by the aquatic creatures

(2) to be eaten. The substrate layer (28) may also contain feed animals (3). Rooting fish (2) can rummage through the substrate layer (28) and eat the food animals (3) there. The preferred

food-technically unmodified, in particular

natural, food animals (3) can be fed alive.

As feed animals (3), e.g. marine worms are used. This includes, in particular bristle worms

(Polychaeta), lugworms (Arenicola marina),

Ringworm (Nereididae) and others. Alternatively or additionally, other types of food animals (3) are possible.

On a nutritional modification of the food animals

(3) by crushing, processing or

Further processing, in particular extrusion, too

Fish food or dry food can be dispensed with. The diet and diet of aquatic life (2) can be significantly improved. The existing in said marine worms Schleimantel affects, for example, particularly health-promoting. Bristleworms, for example, form one in their natural habitat

important ingredient in the diet of many

commercial fish and crustacean species. As such, they contribute to a particularly good digestibility and strengthening of the immune system.

The feeding animal production can be integrated into a water cycle (13) of the culture water (5) in the aquaculture plant (1). This can be beneficial for compatibility. The mutual exchange of

Metabolites (chemical messengers, amino acids, etc.) by the common culture water has a positive effect on the growth and the housing conditions of

aquatic creatures (2).

The container (22) with the feed animals (3) can on the one hand form a feed animal filter (7), in particular a worm filter, which filters particulate matter from the culture water (5). The feed animal filter (7) is with the

Culture container (6) in a filter circuit (14) of the

Culture water (5) connected. The container (22) with the feed animals (3) also has at the bottom (59)

Substrate layer of the aforementioned type, in particular a sand layer or a sand-containing layer on.

The particulate matter can be particulate excretions of aquatic organisms (2) in the culture vessel (6),

Food residues or other solids. They are taken up by the feed animals (3) and removed from the culture water (5). The feed animals (3) can also filter plankton and microorganisms from the culture water if necessary. Furthermore, a feeding of the feed animals (3) from the substrate layer (28) by means of their jaws is possible. In particular, the marine worms (3) can with these be fed particulate substances. On the other hand, in a substrate layer (28), in particular a

Sand layer, the feed animal filter (7) more

Purification processes of the culture water take place, e.g. Nitrogen removal, mineralization, nitrification, denitrification and Annamox.

The feed animal filter (7) and the culture container (6) are further connected in a feeding circuit (15). The

Feeding animals (3) serve as live food for feeding the aquatic organisms (2) and are transferred in a suitable manner into the culture container (6).

The algae reactor (9) may also be incorporated into the feeding circuit (15). In a modification, the algae reactor (9) and the container (22) can be fitted with the

Feeding animals (3) in an independent feeding circuit (15 ') be connected.

In both variants, the algae reactor (9) is preferably designed as a photobioreactor for the microalgae cultivation. In the algae reactor (9), algae, in particular microalgae, are grown in an algae suspension (40). The algae can be supplied with nutrients and light for photosynthesis. The algae production cycle may e.g. 1 to 2

Take weeks.

The algae suspension (40) may be used to feed animals (3) for their nutrition over that shown in FIGS. 1 and 2

Water cycle (13) are supplied. The algae suspension (40) can also enter the culture container (6). The feed animals (3) and the aquatic organisms (2) fed with them can be healthy and without pollutants by means of the algae in a natural and appropriate manner

be fed cheaply. If necessary, the aquatic life (2) and the feed animals (3) other and additional food can be supplied. In which independent feeding cycle (15 ') can be an access of algae, especially algae suspension (40), in the

Culture container (6) completely or at least

be prevented as far as possible.

The container (23) for the rearing of plants (4) can function as a filter (8), in particular a plant filter, for the excretions of the aquatic organisms (2) dissolved in the culture water (5). It can be assigned to the feed animal filter (7), in particular downstream. Part of the containers (23) may also primarily serve plant breeding and have less or no filtering function.

FIGS. 18 to 21 show a plant filter (8) in two variants.

It has in both variants one or more open at the top, trough-like container (23) with a fluid inlet (33) and a fluid outlet (29). The

Plants (4) are adapted to the respective culture water (5). In the illustrated embodiment, salt-tolerant plants or halophytes, in particular

Queller, for use.

The plants (4) are held in the variant of Figure 21 in a hydroponic (35) or hydroponic culture in the container (23). The plants (4) are rooted in an inorganic substrate, which is held in water-permeable plant pots. The plant roots can thereby from

Culture water (5) are flowed around. You can do the im

Culture water (5) absorb dissolved excreta as nutrients and purify the water.

The plants (4) can be useful and edible plants, eg, swelling. They are nourished by the precipitates dissolved in the culture water (5) and can be harvested in due course. At freshwater operation, others will suitable plants (4), eg vegetable or salad plants used.

The fluid outlet (29) of the plant container (23) can in a similar manner as in the culture container (6) and in

Feed animal container (22) may be formed. The training will be explained below.

The plant filter (8) or the container (s) (23) can have a flooding device (36) with which the water level can be changed relative to the plants (4). As a result, it is possible to alternately simulate ebb and flow for salt-tolerant plants, wherein the plants (4) are not or only partially bathed in the root area and at times completely by culture water (5).

The container (s) (22) for rearing feed animals (3) or the feed animal filter (7) may likewise have such a flooding device (36). This allows a sea-like environment with low and high tide for the feeding animals (3), especially the marine worms,

be simulated. This allows the recording of the

Excretions and the algae by the feed animals (3) from the liquid are facilitated and optimized. The excretions and algae can also be found on the

Substrate substrate layer (28) and here from the

Feed animals (3) are eaten. In general, an e.g. through the low tide simulation or otherwise

prolonged residence time of the culture water (5) in the

Feed animal filter (7) and / or plant filter for

Optimizing the filter function contribute.

The flooding device (36) can change the relative water level in different ways. In the embodiment shown, for example, the plant pots of the hydroponics (35) are interconnected by a carrier and can in their altitude within the container (23) with a controllable actuator can be changed. In another embodiment, the water level (41) can be increased and decreased. In a third variant, a mutual adjustment is possible.

An increase and decrease in the water level (41) in the various stacked containers (22,23) or in the tower or cascade arrangement is possible in the following manner. Culture water (5) is continuously pumped into the container (22, 23) by the fluid inlet (33) until the water level (41) reaches the overflow point of the siphon (31). If this point is exceeded, forms in the drain pipe (30) by the suppression of a suction lever effect. This causes the culture water (6) from the container (22,23) is emptied faster than it can be refilled. Once the water level (41) has dropped to a critical point, the siphon (31) draws air and the siphon effect collapses. After that, the principle begins again.

The bottom-side substrate layers (28) or

Hydroculture layers have a slope of e.g. 8% up.

At its lowest point, the siphon (31) is at the end of the drain pipe (30) projecting into the container (22, 23). This allows the substantially complete emptying of the culture water (5) from the container (22,23) and the short-term draining of the soil substrate. This process is important for the oxygenation of the substrate and the optimal functioning of the feed animal filter (7) or plant filter (8).

Figures 1 and 2 illustrate a hydraulic circuit diagram of the first variant of the aquaculture plant (1) for the connection of culture container (6), feed filter (7),

Filter (8) and algae reactor (9). The culture water (5) is in the aquaculture plant (1) in a closed

Water cycle (13) out. If necessary, it can a water supply (10) fresh water to be supplied. At a water discharge (11) spent culture water (5) can be removed from the circuit (13). Furthermore, in the water cycle (13) a water treatment (20)

be arranged.

For the circulation of the culture water (5) in the water cycle (13), one or more pump sumps (16, 18) are provided with one or more associated pumps (17, 19). The sumps can be used as sump for the

Culture water (5) to be formed. A plurality of fluid connections (12) and a plurality of consumers or components (6, 7, 8, 9) of the aquaculture installation (1) can be connected to a sump (16, 18). The fluid connections (12)

between the different components of the

Aquaculture plant (1) are said by the

preferably closed lines formed.

According to Figures 1 and 2, the culture container (6)

on the outlet side via a fluid connection (12) with a first pump sump (16) connected on the input side.

On the output side, the pump sump (16) has several

Fluid connections (12). He is on the one hand via a return line (24) with the fluid inlet (33) of the

Culture container (6) connected. In the return line (24), the aforementioned water treatment (20) may be arranged. Furthermore, the pump sump (16) via a fluid connection (12) with the feed animal filter (7) connected upstream.

On the outlet side, the feed animal filter (7) is connected to a second pump sump (18). From this pump sump (18) of the filter (8), in particular plant filter, fed. The culture water (5) can flow back from the filter (8) via a return line (26) into the second pump sump (18). This can be done for example by gravity. Furthermore, the culture water (5) from the second pump sump (18) via a return line (25) on Feed animal filter (7) are conveyed past the first pump sump (16).

The algae reactor (9) is also over one

Fluid connection (12) to the second pump sump (18) connected to the inlet side. In this fluid connection (12) may be the aforementioned inlet and outlet (10,11). On the outlet side, the algae reactor (9) is connected to the

Feeding animal filter (7) connected.

Part of the fluid connections (12) may be active

Delivery lines are formed, in which pump pressure is pending. Other fluid connections (12), in particular the return lines (24, 25, 26) can be passive feed lines in which the culture water (5) flows by gravity.

Figure 2 shows the hydraulic circuit diagram of Figure 1 and in addition the spatial allocation of the components of the aquaculture plant (1). In this case, one or more discontinuous fluid connections (21) can be seen, through which the water flow can be shut off temporarily. Such a discontinuous fluid connection (21) is e.g. to the inlet and outlet side

Fluid connections (12) of the algae reactor (9) are arranged.

As Figure 2 illustrates, the culture water transport through the feed animal filter (7) and / or through the filter (8), in particular plant filter, by gravity and in a cascade-shaped filter arrangement. The pump (17) conveys the culture water (5) from the first

Pump sump (16) via a fluid connection to

Feed animal filter (7), in particular to the upper

Fluid inlet (33). From this fluid connection (12), the return line (24) branches off to the culture container (6) and its fluid inlet (33). From the culture container (6), the

Culture water via the fluid outlet (29) by gravity to the lower lying first pump sump (16) flow.

The second pump sump (18) is above the first

Pump sump (16) and arranged below the feed animal filter (7), wherein its pump (19) promotes the culture water (5) to the filter (8), in particular plant filter, and preferably to the upper fluid inlet (33). About the

Return line (26) flows the culture water (5)

on the outlet side of the filter (8) by gravity again to the second pump sump (18).

On the other hand, the pump (19) can pump culture water (5) into the algae reactor (9) on the inlet side via a corresponding valve arrangement and discontinuous fluid connection (21). From here, the algal suspension (40) by

Gravity directly to the feed animal filter (7) or in the fluid connection (12) from the first pump sump (16) flow.

The water flows within the aquaculture plant (1) may vary in size, the distribution over the sump (s) (16, 18) associated with

corresponding control means, in particular valves, takes place. Between the culture vessel (6) and the first sump (16), e.g. 1,000 1 / h over the

Return line (24) recirculated. The container (22) or

Feed animal filter (7), because of the retention time, on the other hand, a reduced volume flow of e.g. Fed 300 1 / h and passed after passing through the second pump sump (18). The hereof the plant filter (8)

supplied volume flow can be reduced even more. He can e.g. 100 1 / h amount. The remaining 200 1 / h can on the return line (25) again the first

Pump sump (16) are supplied.

In the embodiment shown in FIG

Aquaculture plant (1) is an additional reservoir (54) for the culture water (5) in the circuit (13) for the Culture water arranged. It is arranged in addition to the pump sumps (16, 18) which are also present in this embodiment. The reservoir (54) may have a volume which clearly exceeds the amounts of water circulated in the circuit (13) every hour, in particular by a multiple.

The container (23) for growing plants (4) is connected independently with its own fluid connection (12) to the reservoir (54). In this way, a sub-circuit (13a) for the filtration of the culture water (5) and for separating said dissolved precipitates can be formed. The fluid connection (12) can have its own pump arrangement, in particular also its own pump sump. This is in the drawing of

For clarity's sake not shown.

The fluid connection (12) or the sub-circuit (13a) can be connected in a suitable manner to the optionally multiply arranged containers (23). In Figure 3 is a

Embodiment shown in which the containers (23)

next to each other and possibly at the same height are arranged. They are connected in parallel to the fluid connection (12) or the sub-circuit (13a). Alternatively, the aforementioned tower or cascade arrangement of containers (23) is possible. Here, the container (23) in the

Cascade arranged one below the other and e.g. for one

Water flow connected in series by gravity.

The individually or multiply existing container (22) for the rearing of feed animals (3) is on the outlet side via a fluid connection (12), in particular via the one

Pump sump (18), with a fluid inlet (33) of the

additional reservoir (54) connected. This

Fluid inlet (33) is arranged separately from the connection of the one or more containers (23) for growing plants (4) on the additional storage container (54). From the or the containers (22) or from the feed animal filter (7) can be characterized by the deposition of particulate

Excretions of the aquatic organisms (2) filtered culture water (5) independently and independently of the connection of the plant filter (8) are fed into the reservoir (54).

On the input side is the feed animal filter (7) or the one or more containers (22) for rearing feed animals (3) to the other and first pump sump (16)

connected.

A fluid drain (29) of the additional reservoir (54) is connected via a fluid connection (12) with a

Fluid outlet (29) of the culture container (6) connected.

In this way, a further sub-circuit (13b) for the culture water (5) is formed. The culture water (5) collected in the reservoir (54) and at least partially freed from the particulate and dissolved precipitates can be fed directly into the circuit (13) or the return line (24). This can be done by downhill or

Self-pressure or by a pump assembly, possibly with a pump sump done. Alternatively, the fluid outlet (29) of the culture tank (6) can be connected to a downstream common pump sump (16).

In the arrangement shown, the feed animal filter (7) and the plant filter (8) are separated from each other and independently connected to the additional reservoir (54). This will also become independent

Filtering circuits (14a, 14b) formed. The in the

respective sub-circuits (13a, 13b) or

Filtering circuits (14a, 14b) circulated flow rates or volumes of the culture water (5) may be of different sizes. The said filter processes or filter stages can take place simultaneously or with a time delay. They can be carried out continuously or intermittently. The additional reservoir (54) optimizes the entire filtering process. The circuit (13) for the culture water (5) can be supplied from the reservoir (54) permanently filtered and purified culture water (5).

On the outlet side, the feed animal filter (7) or the one or more containers (22) for the rearing of feed animals (3) are connected to the pump sump (18) and its pump arrangement (19). From here at least part of the supplied and with regard to the particulate

Excretions of filtered culture water (5) pumped into the additional reservoir (54).

The pump sumps (16,18) and their collection containers are arranged adjacent. You can one another

Have fluid connection. In particular, part of the pre-filtered culture water (5) from the pump sump (18) into the pump sump (16) can enter directly through the fluid connection. The sumps (16,18) can be housed in a common mixing tank with intermediate wall to separate the sump.

From the common pump sump (16), the culture water (5) is pumped to the culture container (6) and the feed animal filter (7). The flow rates can be equal or

be different in size. In one embodiment, two thirds of the total flow rate to

Culture container (6) and the remaining third to

Feed animal filter (7) promoted.

The additional storage container (54) represents a first, independently inventive modification. It can also be arranged in the first variant of the aquaculture installation (1) according to FIGS. 1 and 2. It can be arranged there at a suitable location, for example between the pump sumps (16, 18). The aquaculture plant (1) can according to another

additional aspect of the invention an additional

Have reservoir (53) for a nutrient solution (5 '). The nutrient solution (5 ') can be based on salt water or on fresh water. The additional

Reservoir (53) may be connected to the aforementioned additional reservoir (54) for the culture water (5)

be upstream and can this if necessary, a fresh nutrient solution (5 ') controlled feed. The

Nutrient solution (5 ') is made from fresh water and

preferably only from inorganic nutrients,

in particular nutrient salts, electrolytes and inorganic fertilizer and minerals and trace elements formed.

The supply container (53) for the nutrient solution (5 ') can be connected on the input side to a further supply container (52) for fresh water or possibly directly to a connection (50) for the supply of fresh water, in particular well water or tap water. The connection (50) may be associated with a filter device (51), in which the fresh water is subjected to intensive filtering. This can e.g. reverse osmosis or ultrafiltration. In the possibly existing storage container (52), the filtered fresh water, in particular

Osmosis water, to be stored.

If a saline nutrient solution (5 ') or

saline culture water (5) is needed, the fresh water or osmosis water or the already

formed nutrient solution (5 ') salt in appropriate

Dosage controlled to be added. For this purpose, suitable mixing devices and mixing containers (not shown) may be present. The storage container (53) for the nutrient solution (5 ') may also be present in the first variant of the culture device (1) of FIGS. 1 and 2. He may also be located there between the pump sumps (16,18).

The additional storage container (53) for the possibly

saline nutrient solution (5 ') can be used with the

Plant filter (8) or the one or more containers (23) for growing plants (4) via its own switchable water cycle (13 ") .This water cycle (13") for the nutrient solution (5 ') can be from the water cycle ( 13) for the culture water (5) to be separated.

According to an independent aspect of the invention, the aquaculture plant (1) may have its own

The plants (4) of the plant filter (8) can thereby be fed independently of the filter circuit (14)

Nutrient cycle (15 ") can be formed by means of the switchable water circuit (13"). in the

Nutrient cycle (15 ") may have its own pump sump (70) or its own pump arrangement. The nutrient solution (5 ') circulated in the nutrient cycle (15") may be substantially larger than the circulated production volumes of culture water (5). Circulation (13a) or filter circuit (14a) with connection of the plant filter (8) to the reservoir (54) for the culture water (5). In the containers (23) for

Rearing plants (4) can increase the nutrient content

reduced and to one for the culture water (5)

bearable level be lowered.

According to another independent aspect of the invention, the aquaculture plant (1) can have its own

Feeding circuit (15 ') for the animals (3),

especially the marine worms. The Feed animals (3) are fed with algae, in particular an algae suspension (40), from the algae reactor (9). The algae reactor (9) and the container (s) (22) for rearing feed animals (3) are connected to one another via their own switchable water circulation system (13 ') for the algae suspension (40).

The algae reactor (9) has a controllable fluid outlet (29), which is connected to its own pump sump (69) and to a pump arrangement. In addition, a controllable or switchable removal point (71) for the withdrawal of the algal suspension (40) and for their other use may be present. Through the pump sump (69) and the pump assembly, the algal suspension (40) in the switchable water circulation (13 ') is circulated. The

Water cycle (13 ') for the algae suspension (40) can be separated from the water cycle (13) for the culture water (5) and the filter circuit (14).

The feeding of the animals (3) can be carried out during breaks in which the filtering process in the

Feed animal filter (7) is stopped or shifted. The nutritional process can be controlled, e.g. on a cloudiness measurement of the water circulation (13 ') circulated algae suspension (40). With progressive

Food intake of the animals (3) from the

Algae suspension (40) clarifies this. After completion of the feeding process of the feed animals (3) with algae, the filtering process of the feed animal filter (7) can be restarted.

In the aquaculture plant (1), the aforementioned

Container (6,22,23,52,53,54) each in one

Single arrangement or a multiple arrangement may be present. In the feed animal filter (7), a plurality of containers (23) for rearing feed animals (3) may be arranged in two or more groups. The groups may each comprise one or more containers (22). These may preferably be arranged in the said tower or cascade arrangement.

The groups of containers (22) are each independent of the circuit (13) for the culture water (5) and the

Circulation (13 ') for the algae suspension (50)

connected. This allows the groups independently and in particular alternately connected to the circuits (13,13 ') or via switchable valves or the like. With

Culture water (5) or the algae suspension (40)

be charged.

The algae reactor (9) can on the inlet side with a

Nutrient solution (5 ') are supplied. It can in particular be connected to the additional reservoir (53). Here, a promotion of the nutrient solution (5 ') can be achieved by a pump sump and a pump assembly or by gradient. The promotion can be switchable as in the other cases. In addition, a treatment of the nutrient solution (5 ') may take place, e.g.

through a UV filter.

In the water cycle (13) for the culture water (5), the aforementioned water treatment (20) may be arranged. This can e.g. assigned to the culture container (6) or

be upstream. The water treatment (20) may e.g. a UV filter and / or an oxygen enrichment and / or a degassing and / or a skimmer

respectively. The arrangement indicated in FIGS. 1 and 2 may also be present in the aquaculture installation (1) of FIG. She is not shown there. In the water cycle (13) for the culture water (5) and / or the nutrient solution (5 ') may further at least one

Be arranged measuring device (43). This can be one

Single or multiple arrangement. A measuring device (43) is e.g. arranged at the pump sumps (16,18) and the local mixing container. The measuring device (43) can detect turbidity and / or pH and / or ingredients in the water. Such ingredients may e.g. Oxygen, carbon dioxide, common salt,

Nitrogen oxides, ammonia, phosphate, metals or

to be like that. A measuring device (43) can also be arranged on a culture container (6) or on a storage container (53, 54) for the culture water (5) or the nutrient solution (5 '). The one or more

Measuring device (s) (43) are connected to the controller (44). Based on the measurement results, the

Aquaculture plant (1) controlled and possibly regulated.

The measuring device (43) can be present in both variants of the aquaculture system (1).

The algae reactor (9) can be designed in any suitable manner. This can e.g. be an education according to WO 2016/012489 Al. Alternatively, the algae reactor (9) may also have a closed container.

Figures 3 to 4 show another embodiment. It is e.g. designed as a so-called open Pond. The

Algae reactor (9) has a water tank, in particular with a nutrient solution (5 '), filled and ventilated and open at the top reactor vessel (27). The

Reactor vessel (27) has a ring-like shape in plan view and is filled with an algal suspension (40). The algal suspension (40) preferably contains microalgae. The algae reactor (9) also has a circulation device (37) for circulating the algae suspension (40) in FIG

annular reactor vessel (27) to form a quiet circulation flow in the flow direction (38). The circulation device (37) is designed, for example, as a paddle wheel with a controllable electric drive motor. The circulation device (37) can be located at a narrow point of the reactor vessel (27). The reactor vessel (37) may also comprise one or more circulating flow conduits (39)

Having algae suspension (40). The algae reactor (9) can be used singly or multiply in the aquaculture plant (1)

to be available.

Figures 6 to 8 show an initially mentioned

Embodiment of the culture container (6). This can e.g. trough-shaped and an elongated,

in particular cuboid shape. The culture container (6) has a fluid inlet (33) at one end and a fluid outlet (29) at the opposite end. The fluid outlet (29) can be an upper fluid outlet

(64) for surface water and a lower fluid withdrawal

(65) for groundwater. Fats, oils and other rather unfavorable constituents in the culture water (5) collect at the water surface or at the water level (41) and can be separated from the upper fluid outlet (64)

Groundwater are deducted. In the area of the groundwater, there may be a calm flow from the inlet (33) to the outlet (29).

On the discharge side and possibly on the inlet side, a trough-like overflow (63) for the surface water can be present. The overflow (63) can be adjustable.

He can e.g. a height-adjustable overflow wall

respectively. The upper fluid outlet (64) opens at the overflow

(63).

On the inlet side can also be an upper fluid outlet

(64), which opens at the overflow (63). At the inlet side of the fluid outlet (64) alternatively an upper Be fluid inlet. This one can be closer to the ground

complete arranged inlet (33).

The fluid withdrawals (64, 65) can each be arranged several times. They can also be adjustable. The lower fluid outlet (65) can be formed in any desired manner and possibly switched or controlled.

At the lower fluid outlet (65), for example, a _V orifice arranged (66) on the end wall of the culture container (6), which is a distance from the bottom of the

Culture container (6) has. Behind the wall-shaped panel (66), a cavity (67) is formed. This is located between the container end wall and the rear panel. The upright cavity (67) is connected in the upper area with the lower fluid withdrawal (65). The e.g. in the

Container end wall recessed cavity (67) may have an upwardly tapered constriction (68). He can e.g. have the upright triangular shape shown in Figure 7. At the upper narrowing area is the fluid outlet (65). The constriction (68) can through the

Side walls of the groove-like and the cavity (67)

forming recess in the container end wall are formed. By this arrangement, a negative pressure can be generated in the region of the lower fluid withdrawal (65). The bottom water located in the lower tank area can thereby continuously and evenly from the

Culture container (6) are deducted.

In the culture container (6) can according to figure (8) a

Be arranged measuring device (43). With this, e.g. The turbidity of the culture water (5) can be detected. In

Depending on the turbidity, the circulation of the culture water (5) and the filter processes can be controlled or regulated. Furthermore, an outlet (61) for emptying the culture container (6) can be arranged on the container bottom. At the bottom of the culture tank (6) is the initially mentioned substrate (28) with the feed animals (3). In the culture water (5) are also the aforementioned

contain inorganic nutrients.

Figures 9 to 17 show a structural design and arrangement of containers (22) for the rearing of

Feeding animals (3). In a similar manner, containers (23) for the cultivation of plants (4)

be educated. The illustrated construction and arrangement of the container (22,23) also has its own

inventive meaning. You can also do it with others

known aquaculture plants (1), in particular according to WO 2016/012489 Al, are used.

The containers (22,23) can be arranged one above the other in a tower or cascade arrangement. Im shown

Embodiment, a plurality of individual containers (22,23) in a stack directly to each other with mutual

Touch and support arranged. In a

Cascade arrangement, multiple containers (22,23)

one above the other and with lateral offset, e.g. in the manner of a stepped terrace arrangement.

Alternatively, a plurality of containers (22, 23) may be stacked at a mutual distance, e.g. tower-like arranged in a shelf or rack.

In the embodiment shown, the individual ones

Container (22,23) has a suitable cross-sectional shape, which may be circular, oval or prismatic, for example. The circular formation shown has constructive and functional advantages in terms of stability, stackability and animal husbandry (3). The individual containers (22) each have a circumferential upright side wall (56) within which a bottom (59) is arranged in a raised position and preferably at a distance from the container bottom side. The floor (59) is supported by support means (62) over the side wall (56). The support device (62) may be formed, for example, by cross members arranged below the base (59), which are fastened to the side wall (56) at both ends and may possibly protrude outwards through the latter.

The floor (59) has a slope (60). At the lowest point of the bottom (59), a closable outlet (61) is arranged on the container (22, 23). This can be located in the side wall (56) and can be operated from the outside. On the floor (59) is the mentioned

Substrate layer (28), in particular in the form of a

Sand layer, with it contained feeders (3) of the type mentioned. By the slope and the

Outlet (61), the substrate layer (28) and the feed animals (3) can be drained and removed.

The side wall (56) of the upper containers (22,23) in the stack has a lower height than the side wall (56) of the lower container (22,23). The side wall (56) of the upper container (22,23) has foot parts (57), which in

Circumferential direction at a distance and with the formation of

Openings (58) in the side wall (56) are arranged distributed. The foot parts (57) are based on a

corresponding annular upper side of the side wall (56) of the next container (22,23) and are guided here. The openings (58) allow ventilation and lighting in the container stack.

In the containers (22,23) is at a suitable location, in particular centrally, in each case a fluid outlet (29)

arranged. He has an upright drain pipe (30) which passes through the inclined bottom (59). At the

The top of the drain pipe (30) is e.g. a siphon (31) spaced above the floor (59) having the function described above. Below the bottom (59), the fluid drain (29) has a transversely directed, e.g.

tubular fluid passage (34), at the lower end the drain pipe (30) is connected. The

Fluid transfer (34) forms the fluid inlet (33) for the next lower container (22,23) and opens at a distance above the bottom (59).

The fluid transfer (34) may be at one or more suitable locations, e.g. at the ends of their tubular shape, have outlet openings (32). In the lower container (22,23), the fluid passage (34) through the

Side wall (56) led to the outside and to a

Be connected fluid connection (12). Depending on

Distribution of the outlet openings (32) on the

Fluid transfer (34) on the upper containers or (22,23), a sprinkler function or a

Surge transfer made. The fluid transfer line (34) may have any other shape, e.g. in a star or ring arrangement.

With the arrangement shown can by the

Fluid transfer (34) in said cascade the

Culture water (5) or possibly, a nutrient solution (5 ') from a container (22,23) are introduced directly into the next lower container in the stack.

Alternatively, another training is for others

Cascade arrangements possible. The illustrated embodiment of drain (29) and inlet (33) with the siphon (31) is also for level control, in particular for the simulation of low and high tide, an advantage.

Figures 18 to 20 show the aforementioned alternative

Forming a container (23) for growing plants (74). This can in low tide / flood mode or in the

Continuous mode can be operated. The container (23) shown has at the bottom a water-permeable, perforated dimpled sheet (72) for receiving a substrate layer (74) with the plants (4) (not shown). The container (23) may have any suitable cross-sectional shape, eg the rectangular shape shown. The container (23) may have laterally on the substrate layer (74) adjacent and laterally water-permeable drainage channels (73) for the fluid inlet (33) and the fluid outlet (29). The inner sidewall of the separately arranged

Drainage channels (73) each form the lateral boundary for the substrate layer (74). The

Water permeability may be at the bottom of the

Drainage channels (73) exist. For the fluid outlet (29), an opening may be present on the channel bottom.

In the dimpled sheet (72) provided with mountains and valleys, the substrate layer (74) is picked up and supported. The perforations may be present on the top walls or the oblique side walls of the dimpled sheet (72). The substrate layer (74) may be of any type

suitable material, e.g. Earth or sand or larger particles of a hydroponic culture. The watering of the substrate layer (74) can take place via the dimpled sheet (72) from below. If necessary, the water level can also be changed in the aforementioned manner, as well as low tide and high tide can be simulated. Alternatively or additionally, sprinkling of the plants (4) is also possible. This is possible and advantageous in particular in connection with the nutrient cycle (15 ").

In the aquaculture plant (1), the above-described fluid connections (12) and the various

Water circuits (13, 13 ', 13 ") valves, valves or other controllable switching elements, with which the

Flow can be blocked or released.

Remote controllable switching elements may also be connected to the controller (44). Furthermore, other flow-regulating devices, such as throttles or the like. to be available. The above-described aquaculture plant (1) is used in the various variants for the rearing and fattening of aquatic organisms (2) and food animals (3),

especially marine worms. For this purpose, suitable pups are inserted into the container (6,22) and

raised or fattened. In the case of a longer breeding period, young animals of different age groups can be kept separately in different containers (6,22). After the harvest will be a new one

Poultry stock introduced into each emptied container (6,22).

In an independent invention aspect is a

Offspring (2 ') intended for aquatic life and / or a progeny (3') for food animals. In the

Offspring (2 ', 3') can reproduce and reproduce aquatic organisms (2) and / or food animals (3) with suitable parent animals. The offspring (2 ', 3') can each into the aquaculture plant (1) in both

Variants be integrated. The offspring (2 ', 3') can be converted into the containers (6,22) of the aquaculture plant (1) for further rearing and fattening when a suitable degree of ripeness is reached.

As FIG. 3 illustrates, the aquaculture installation (1) has a device (47) for captive breeding (2 ') of aquatic organisms and / or a device (47) for captive breeding (3') of food animals, in particular marine worms. The respective device (47) can be integrated into the existing circuit (13) of the culture water (5). Furthermore, an integration of the device (47) for

Offspring (3 ') of feed animals in an existing feeding circuit (15') possible. Alternatively, your own water and feeding circuits may be present. The device (47) provides fertile favorable

Ambient conditions for the offspring (2 ', 3') ago.

In this case, natural and e.g.

Seasonal environmental conditions are simulated. Marine worms, especially lugworms, multiply primarily under natural environmental conditions that prevail in the fall, especially in October, a year. For some species, e.g. Full moon may be useful or necessary as stimulation for reproduction. With the

Device (47) can be simulated such environmental conditions. This also allows the
