Description
A BREEDING FACILITY FOR MARINE ANIMALS, PARTICULARLY FISH.
The present invention relates to a breeding facility for marine animals, particularly fish, comprising a tank with a preferably circular cross- section designed to be filled with water up to a certain level. The facility may be land-based or may consist of a sealed tank or bag that is submerged in water.
The majority of breeding facilities for consumer fish found today are so-called fish farm ponds, enclosures which are placed in the sea. These pond enclosures consist of a net bag, and water is renewed with the aid of the natural current in the water. There are consequently some strict limitations with regard to placement of such fish farms since, first of all, there must be sufficient¬ ly strong current — without its being too strong, there must not be too much sea, and it must not be too shallow or too confined. Fish farms of this type put a very heavy strain on the sea envir¬ onment. The fish farms polute to quite a high degree because of excrements from the fish and feed remains that float out into the surrounding water through the walls of the net bag. Fish in captivity are readily susceptible to various diseases and para¬ sites, and large quantities of medicaments are therefore used in connection with the fish farming industry. These medicaments are often administered in the feed, and will spread into the sur¬ rounding water where the medicaments are consumed by wild fish, sea fowl and animals — for example, otters — that hunt the fish in the ponds or outside these enclosures. It is quite conceiv¬ able that resistant groups of bacteria could arise, which could result in irreparable damage to the environment and which might also be transmitted to humans. The fish in the open ponds are moreover vulnerable to contagion from wild fish, and to para¬ sites. Heavy alga growth, high incidence of jellyfish and the like can cause catastrophic death rate of fish in the farming ponds.
The purpose of the present invention is primarily to eliminate
the above mentioned disadvantages and to optimize fish farming with regard to both land-based systems and water based facili¬ ties. This is achieved according to the invention by a fish farm facility of the type mentioned introductorily, which is charac¬ terized by the combination of the following features: a) that it is connected to a circulation pump with an inlet near the bottom of the tank and an outlet near the surface of the water in the tank, b) that it is connected to a supply pipe or pipes for fresh water and a discharge pipe to provide for a renewal of the water over time, c) that the inlet from the pump is directed tangentially or approximately at a tangent within the tank to provide a constant, circulating current in the water, d) that in the bottom there is provided a well for collection of excrements and feed remains and other impurities, and e) that to the well is connected a suction pipe for the removal of the impurities.
Additonal features and advantages will be disclosed in the depen¬ dent claims.
Several advantages are achieved by means of the facility in accordance with the invention. First, one gains control of the environment, both in the fish farm itself and — in the case of a water-based system — in the surrounding milieu. The constant whirlpool in the container or tank will collect solid particles centrally at the bottom and will trap them in the well, from which the impurities can be transported out through the suction pipe.
By circulating the water through an air lift pump one can achieve purification of the water. The air lift pump, of course, func¬ tions by blowing in large quantities of air that rise up through
a vertical pipe as bubbles. The fish take in oxygen from the water by means of their gills and discharge CO-, together with urinary products, particularly in the form of ammonia. When water containing CO-, and ammonia is sucked into the air lift pump, the CO-, gas will be taken up by the rising air bubbles. The same thing will happen to some extent with regard to ammonia and other substances. , The most important thing, however, is that the water is ridded of CO-,. This air that flows in at the sur¬ face of the tank is air-enriched so that one constantly obtains a new supply of oxygen-enriched water. The water in the fish farm is thus circulated the entire time and is freed of CO-, and en¬ riched with air. Smaller amounts of new water are being supplied the whole time, essentially in order to hold the ammonia content in the water at an acceptable level. Because there are used only small amounts of fresh water, it would be expedient to maintain a higher temperature in the system, at least in certain periods of the year. In this connection a heat pump can be used, inasmuch as the heat in the discharged water and/or the heat in the surround¬ ing water can be utilized, in the case of a water-based system.
The fish farm in accordance with the invention would in addition be very suitable as a land-based facilit}', which is quite advan¬ tageous from the point of view of several other conditions. Th objections to a land-based system have been that pumping of flow ing water from a nearby water source has been very demanding i terms of energy. With the system according to the invention, th water circulates through the air lift pump without requiring an energy to lift the water, and fresh water is added in only smal amounts, which thus requires little energy. The system is totall controlled with regard to any strain on the outside environment, and also with regard to the influence of the outside environmen on the fish within the facility.
Where a sea-based system is concerned, the small amount of wate
that is necessary in order to replenish the water in the tank could be taken from remote places; if, for example, the surface water is polluted or too cold or too warm, the water can be taken from deeper lying layers. Due to the fact that we are talking about small amounts of water, the pumping costs would be rela¬ tively modest.
The system has been the object of particular interest in areas where warm ground water is found. In a fish farm according to the invention, located in an area where there is access to warm ground water, consumer fish of very valuable types that have a high price on the market can be farmed. Here one thinks primar¬ ily of sturgeon, which brings 2 to 3 times as high a price as salmon on an international market. The sturgeon requires a water temperature of about 25 C, and this can very easily be obtained with the aid of warm ground water in Southern European countries where there is rich access to warm ground water at a relatively modest depth below the ground level.
In accordance with a further development of the invention, carp pools may be attached to the system. The pipe from the well that is placed at the bottom leads to the carp pool, and the same per¬ tains to water from the outlet from the tank-. These pipes will carry large quantities of nutrients to the water in the carp pools. The carp in a carp pool are not given feed, but live ex¬ clusively on the vegetation that grows in the carp pool. In order to achieve sufficient growth, large quantities of nutrients must be added. In accordance with the invention these nutrients can be supplied at no cost from the fish farm.
The invention will now be explained more fully in the following, with reference to the drawing that schematically shows an embodi¬ ment form for a fish farm according to the invention.
Figure 1 shows the fish farm seen in perspective with some of the wall cut away, and
Figure 2 shows the fish farm seen from directly above.
The fish farm according to the invention consists of a tank 1 with a circular wall 2 and a bottom 3. To the tank 1 is con¬ nected an air lif pump 4 with an intake 5 at the bottom of the tank 1. The outlet 6 from the air lift pump passes through the wall of the tank in the proximity of the surface 7 of the water fill in the tank. The inlet pipe 8 is directed tangentially within the tank so that a whirlpool current is formed in the water in the tank, as shown with arrows 9. The water level in the tank is regulated by an overflow pipe 10. Air to the air lif pump is supplied through an air conduit 11 and water supply for renewal of the water in the tank is brought in through the pipes 12.
In the bottom of the tank is provided a well 13 haying a filter 14. To the well 13 is connected a suction pipe 15.
By means of the air lift pump, continuous circulation of the water in the tank 1 is obtained. At the same time, the water is oxygenated by means of the air bubbles in the air lift pump, and the water is cleaned by virtue of the CO- in the water being taken up in the air bubbles floating up and passing out into the open air. Through the supply pipes the water is renewed over time. The water that is added may be heated to maintain a con¬ stant temperature in the water in the tank. The polluted water that runs out from the tank through the overflow pipe 10 can go either to carp pools or to a purifying plant. The pipe 15 that sucks out solid impurities from the well 13 can go to the build¬ up of fertilizer or to carp pools for their fertilization. Th whirling current collects pollutants', such as feed remains and
excrements from the fish, centrally in the tank, and these will descend and be gathered into the well 13.
As will be understood, one would be able to obtain full control with a fish farming facility according to the invention. There is used a sealed tank or bag, so that no contaminants are brought into the surrounding environment. Excrements and feed remains that descend into the well are pumped to a plant that takes care of these substances as fertilizers. The overflow water, which is only very slightly polluted, can be conducted to a conventional purifying plant for waste water. As regards those periods when the fish have been given medication, the tank can be drained completely after the medicating and replenished with fresh water. The water that is contaminated by medicines can be purified in a special facility.
