The invention relates to a method of rearing - it has now surprisingly been found that 'one d Keeping carp and other useful fish 'Carp and other useful fish in' water tanks in water tanks with cleaning and tempering even with a much higher weight ratio fish tion of the -water in the cycle.-The invention will attract water and unusually quickly in the following on the basis of the rearing and keeping of 5 'can bring growth, if you do that in the cycle Karpfen explained, however, is also underfished for other useful waters of activated sludge clarification applicable. 'pulls.

The rearing and keeping of carp was therefore the subject of the invention is a method -to date in natural or artificially pent-up areas for rearing and keeping carp and others water, which on the basis of collected experience io useful fish in water tanks under cleaning and They are fertilized and planted, and the water is regularly tempered in the cycle, which means that the water is kept cool be fished. In addition, the indicates that the circulated water Supplement to the natural food artificial food in a known way freed from suspended matter and through termmittel supplied Since it is cleaned in such a fish - organic-biological activated sludge clarification attitude is practically hardly possible, with individual is.

According to the teaching according to the invention, carp can be required, which are heated in each case, whereby the heat is lost and other useful fish are not only lost with the running water - higher weight ratio fish to water from From the German utility model 1852 645 is about 1: 100 and even more than that, a fish farm can be built with a large number of times without any difficulty, but also surprisingly high weight increases in fish are achieved in series, one after the other, with water flowing through them 40 which not only overcomes all previous aquarium experiments -Fish tanks are known, each of which is met by a win, but also considerably above the growth plate in a "fish tank and a pure water speed of pond carp. This is how containers can be subdivided. With this arrangement, weights of carp flow after one year of life This can be reached from the fish tank through a - which are about twice as high as the filter layer in the pure water tank, and from this - 45 the average weights of 3-year-old pond carp, sem over a trickle plate into the following fish- The carp raised according to the invention are covered and will After flowing out of the last one, it has a better taste quality because, on the other hand, the pure water tank is conveyed back to the first fish tank by a pump and a set for the yellowish, soft and high-fat meat filter tank. the pond carp have white and firm meat. However -the -between the individual 50 The so reared carp are at the end of the fish tank and clean water tanks and in the filter year in which they emerged from the spawn, tank contained! Filter materials can often be exchanged - up to a weight of around 1 kg. In addition, the water cycle is grown and can be spawned at the beginning of the next year through the "successive fish tanks". Thus, in the -like -the “water level in the individual fish basins, an annual turnover in aquariums is hindered by the clogging of the filter layers, in contrast to the three-pomeranian pond management

boneless or boneless fish breeds extraordinary relieved .: Besides' can with essential with less effort and in a much shorter time in a small space large quantities of high quality Edible fish are produced for human consumption.

In the following, the advantages of the invention are further illustrated by means of examples.

example 1

. In an experiment, 47 half-year-old carp weighing between 8 and 10 g each were put into the Water tank of a device according to the invention used. This increased within 12 months The average weight of the fish was 805 g, while the pre-grown ones reached a weight of 1755 g. One Another group of similar carp, however, which were kept in ponds, arrive on At the end of her second summer an average weight of 300 to 400 g. In the case of the in, Aquarium * o The carp kept grows during the respective winter months.

Example 2

A group of 300 1 year old carp from ag They came from a poorly run business and were survivors of an infectious ascites epidemic were, in July with an average weight of 28.2 g in the water container of an invention Plant used. The average weight increased through November 29 of the same year towards 200 g. Pre-growths in this group weighed 1165 and 1130 g at the end of the year.

35

In a further experiment a group of three two-summer carp with an average weight was used of 140 g used in a water tank of the system according to the invention. After exactly After one year of keeping the weight of the fish was 2815, 2285 and 2210 g. The weight of the fish had thus increases twentyfold within one year.

45

In a water tank of the invention Plant was used in July newly hatched carp fry, which usually end up in the pond in summer reached a piece weight between 30 and 50 g. In December, the same year it was The fry of carp have already grown to an average weight of 500 g each.

The vorstehend.gemachten information on the weight ratio of fish to water are based on the total weight of the circulating water, ie ge velvets amount of water in all water containers ■ plant iowie the plain, activated sludge, Sam'mel- and Aufheizbecken including all ^v VerbiridunglsIeltMgen . ^; If you 'only' look at the water content of the 'respective' fish tank 'yourself', - the weight ratio of fish to water can be down to 1:10. yes even up to about 1: 3. For example, eight carp with a total weight of 6985 g were kept in a water tank with a water content of 401. The weight ratio of fish to water is of course influenced by the ratio of the amount of water held in all fish tanks to the total amount of water in the system of different ages, each time the adult animals are removed and the container that has become free is reoccupied. Although, for economic reasons, efforts will normally be made to work with as high a weight ratio of fish to water as possible, the teaching according to the invention can also be carried out with a lower fish population.

An exemplary embodiment of the invention is shown in the drawing

In the. The fish are reared in water containers Λ. From the water tanks A lead drain lines to the primary settlement tanks K and of these surplus lines to the activated sludge basin S. The pre-treated water then flows into another clarifier K "3 and the purified water into a collection Z, in which a submersible pump M is provided the electric pump M suppresses the purified water through a pressure line into a heating vessel H, which is connected to the water tanks A by a connecting line with distribution pipes V
