Abstract
A B S T R A C T
The invention concerns a device and a plant for breeding fish, shellfish etc.
One or several tanks of a non rigid material are lowered into the water. Each tank (1) has at least one inlet (2) and at least one outlet (3) for water. The inlet and the outlet are so arranged that the water level in the tank is somewhat above the surrounding level, thus obtaining that the walls of the tank are tightened out by the higher static pressure.

A DEVI OE FOR BR~EDING FISH, SHELI,FISH ETC.
The in~ention concerns a device Eor breeding fish, shellfish etc.in tanks lowered into water.
The most common type of fish breeding today means that the fish is contained in nets lowered into the sea, a lake or a water current. Fresh water is then continuously fed which is a condi-tion for the breeding, unless special purification plants are used.
The disadvantages with such systems are several.
Purifications and food waste may be collected at the bottom under the net, poison the surroundings and sometimes even the fish. In addition there is often a big waste of food and the nets must quite often be cleaned erom alga. Finally the breec1-in~ ls dependent on ~h~ temperature Oe the surroundincl water as well as on the contents oE oxygen and natural nouris~ment.
These conditions are of course depending on the season which means that the growth sometimes is very low.
Fish breeding in closed tanks provided with purifica-tion plants has up to now turned out to be too expensive to be utilized in a large scale, primarily because the breeding must take place on land.
The invention provides in a system of tanks for breeding fish and the like for use in a liquid environment, apparatus comprising in ~ombination:
a first cylindrical fish tank of a non-rigid material having a first inlet and a ~irst outlet, said first inlet and outlet being below the surrounding li~uid line and dimensioned so that the liquid in said first tank is at a level higher than the liquid environment surrounding said first tank, and said 5~
- la -first inlet is directed tangentially to said first tank and said first outlet is directed tangentially from said first tank, whereby a rotating liquid flow is created in said firs-t tank;
first means extending from -the bottom of said first tank for collecting sludge and gas, said first means including a first conically shaped hopper having a first cover in-clined toward the cen-ter of the hopper and defining a first central hole, a first screening member located adjacent said first central hole for preventing gas from entering said tank and for permitting collection and evacuation of the gas at the upper interior periphery between said first hopper and cover walls, a ~irst protet:lon ~cr~en posit:loned ovcr ~aid ~:lxst central hole to prevent dead :E.ish and the li.ke :Erom fallin~
into said hopper, and a first sludge outlet extending from -the narrow portion of said conical hopper;
a feed line coupled to said first .inlet; and a sludge line coupled to said first sludge outlet to transport the sludge to a collecting tank.
Preferred embodiments of the inven-tion are described below with re-ference to the enclosed drawings, wherein:
Figure 1 shows a tank according to the invention seen from the side, while Figure 2 shows a plant for fishbreeding with several tanks seen from above.
In the drawings 1 stands for a tank having an inlet and an outlet 2 and 3 resp. 4 stands for a sludge collector with means 5 and 6 for collecting of gas, 7 a protection ~LZ559~
cover and 8 an outlet. 9 stands for a common feeding line and 10 a collecting tank for sludge.
A preferably cylinder formed tank 1 made of canvas, soft plastic or some other non rigid material is lowered into the water, for instance the sea, which tank contains fish or other water animals. The tank has an inlet 2 and an outlet 3 so dimensioned, that the water level in the tank always is above that of the surrounding water, thus obtaining that the tank walls are tightened out by the higher static pressure.
According to a preferred embodiment for fish breeding the inlet is tangentially arranged, thus causing a circular flow in the tank. This arrangement has two advantages.
The fishes are forced to swim against the current around i.n the tank which stimulates the Eeeding and minimizes the waste. In addition ~ollutions are collectd in the center of the tank and are there easy to remove.
The tank water is taken from a point in the sea where the water temperature is suitable and/or where the oxygen content and the amount of natural nourishment are big.
The transport may be carried out by an equipment described in the Swedish patent No 8202429-0, (L-E Nyman 6-1).
In the center of the tank hottom there is a device for collection of sludge designed like a hopper having relatively steep sides. The pollutions on the tank bottom will then be collected in the hopper and concentrate in its bottom. The hopper is provided with a cover 5 inclined towards the center having a central hole which in its turn is screened by a body 6 at a distance below the cover.
In this way gas generated in the sludge is prevented from coming up into the tank 1 and poisen the fish. The gas is instead collected at the perlphery in the upper part of the hopper and may be evacuated. In order to prevent bigger bodies, such as dead fishes, from falling into the hopper, it is preferably provided with a net or a protection sheet 7.
~ZS5~
The lower part of the hopper 4 is connected to an outlet pipe 9 through which the sludge is removed towards a collectin~ tank 10. This may be carried out by attaching the pipe to a pump or by temporarily increasing the pressure in the tank 1 in comparison with the pressure in the tank 10. The latter tank may be common for several breeding tanks and is arranged to treat the sludge in a suitable way. The system is closed and no pollutions will be let out to the surroundings.
In order to secure feeding of water from outside in case the normal feeding should break down, the upper part of the tank 1 may be provided with barred security openings.
~nder normal conditions the openings are closed from i.nside by covers pressed against the\,valls by the static pressure.
In case of a stop, th~ pressur~s ar~ equalized, the openings are uncovered and water flows into the tank to keep the fishes alive until the error is corrected.
The device according to the invention and the plant that may be built by help of the device have a long range of advantages compared with previous known solutions. Some of the most important are the following:
The tank is manufactured ln a relatively inexpensive material and can, thanks to the big water exchange, be treated to minimize the growth of alga. The closed tank also means that disease in one tank is not spread to other tanks in the same plant.
The water rotation in the tank means that the fishes swim and eat maximally, thus minimizing the waste. The rotation also mears that the pollutions are collected in the center for easy removing.
Fresh water may be taken from a point where the temperature is suitable, where the oxygen content or the amount of natural nourishment are good.
The device and the plant may be placed anywhere. It does not pollute the surroundings and is not influenced by - .
lZSS9~
pollutions in the latter. In addition ice may be avoided by feeding warmer water during wintertime.
Collecting, sorting and disinfecting of the fish may be simplified by pumping out the water in the tank, the walls then being folded and the bottom being brought upwards towards the surrounding water surface.
'`
In the separately arranged sludge collecting tank an ~-' effective treatment may be carried out which does not have any effect on the environment. The system can also be provided with an integrated complete purification system.
