Definitions

  • the invention relates to a plant for the breeding of fish in recirculating flowing water, and comprising a fish basin which extends from an inlet basin and ends in an outlet basin, and where the surface of the water at the inlet basin lies higher than at the outlet basin.
  • Hitherto-known plants normally consist of open basins in which the fish are kept, and where the water is recirculated after having been cleaned and treated.
  • the plant according to the invention with a fish basin which consists of a pipe through which the water can flow has the advantage that it has shown to improve the environment for the fish in a decisive manner. This is because the fish regard the pipe and the water flow as a natural watercourse, and tests have shown that their development and thus their growth far exceed that which it has hitherto been possible to achieve in traditional open basins.
  • the amount of fish per unit of water volume can be increased without causing the fish any inconvenience, merely providing that the quality of the water is in order.
  • fig. 1 shows a plant seen from above
  • fig. 2 shows the plant seen in perspective from the one end
  • fig. 3 shows the plant seen in the direction III-III in fig. 1, and
  • fig. 4 shows a side view of the plant in the ground.
  • the plant comprises a U-shaped pipe which, as shown, can consist of two similar pipe sections 1 connected at the end with a bend 2. As will be seen in figs. 2-4, the pipe extends in a declining manner, in that the one end is placed higher than the other end.
  • Each pipe end is connected to a vessel or basin, one of which is connected to the highest-lying pipe end and functions as water inlet basin 4, while the other functions as water outlet basin 3.
  • the diameter and the length of the pipe depends on the capacity of the plant.
  • the pipes 1, 2 and the basins 3, 4 are preferably made of dark-coloured synthetic material which can be reinforced with glass fiber.
  • the pipe 1 In order to be able to carry out an inspection of the plant, it can be provided with one or more inspection pipes 5 through which it is possible to see into the pipe 1, 2. Growth lights or UV lamps can possibly be mounted in one or more of these pipes.
  • the inlet and the outlet basins 3, 4 are square vessels with an inclining bottom 6 which opens out in a pipe stub.
  • removable covers 11 can be mounted over the basins 3, 4 and the pipes 5.
  • the fish 22 in the water 21 are thus protected against being frightened and stressed, in that they will thus reside in the water completely without the ingress of light.
  • evaportation is hereby reduced to a minimum, and infection of the water and herewith the fish is prevented.
  • a pipe 12 which can be connected to a not-shown cleaning plant, such as a sedimentation or cyclone separation plant, for the separation of the precipitational organic refuse products from the fish in the form of faeces and feedstuff remains.
  • a not-shown cleaning plant such as a sedimentation or cyclone separation plant
  • a valve 13 can regulate the discharge 14 from the pipe 12.
  • a pump 15 which pumps the water through a UV-0 3 reactor 16.
  • This comprises an 0 3 generator 17 which is supplied with oxygen or air 8, and this enriched water is supplied in counter- flow to the inlet to a UV generator 19 which both sterilizes and cleans the water, especially of ammonia and urea.
  • the treated water is then led through a pipe 20 possibly via a pump 15 to a bottom stub in the inlet vessel 4, whereby the closed circuit in the plant for recirculating water is established.
  • one or more flow-generating and oxidizing pipes can be mounted between the basins 3, 4.
  • This pipe 7 extends from the side of the outlet basin 3 downwards to a depth of up to eight meters.
  • the end of the pipe is provided with a bend, and there is also mounted an inlet pipe for air 10 which is applied to the water by means of an air pump 9.
  • fig. 4 is shown how a plant according to the invention can be placed under the earth 23. This has the advantage that the temperature in the plant can be held relatively constant, and also that the plant can be established under a greenhouse or the like where the separated organic waste can be used as a valuable fertilizer and earth improvement agent.
  • the plant can have a very high degree of recirculation, which contributes greatly towards the plant's low consumption of water and energy.

Abstract

Afin d'obtenir le meilleur environnement possible pour des poissons élevés dans une installation à eau recyclée, le bassin de l'invention a la configuration d'une conduite (1, 2) reliant deux bassins (3, 4). Le fait de pomper de l'eau d'un bassin (3) vers l'autre bassin (4) au moyen d'une pompe à air (9) et d'une conduite de raccordement (7, 8) permet de faire s'écouler l'eau (21) dans les conduites (1, 2) et de procéder à une oxydation de l'eau. Cet agencement permet aux poissons (22) de demeurer paisiblement dans le bassin, et en même temps de percevoir l'écoulement comme un cours d'eau naturel, ce qui donne lieu à un niveau de santé et un taux de croissance élevés. L'invention permet d'atteindre un rendement et une qualité élevés avec une très faible consommation en eau et en énergie.
