Definitions

  • Fish farm The present invention is related to a land based or closed sea based fish farm. 5 Fish farming of today is often accomplished in closed units such as in containers or tanks on shore or in tanks in water.
  • the different fish species may be grouped into two main types in connection with fish farming, fish demanding volume and 10 fish demanding area to lay on or rest.
  • volume demanding fishes such as salmon
  • open systems such as sea beds
  • Other fishes demanding volume such as fresh water trout
  • land based systems such as a cages
  • Area demanding species to a very high extent rest on the sea bed or bottom and does not efficiently utilize a large volume, even if accessible.
  • the size of the accessible farming area is however essential.
  • Area demanding fishes are for example ocean catfish and flatfish species as halibut, hirame, turbot, o sole and plaice.
  • the above mentioned disadvantages are overcome with the fish farm according to the present invention. Additionally even other advantages are achieved.
  • the present invention represents s a solution to these major problems by combining the advantages of the two existing systems as well as introducing new features making internal transportation easy in combination with a good self-cleaning system.
  • the rational and compact solution of the present invention reduces operational cost and minimizes the 0 investment involved.
  • the fish farm according to the present invention provides a possibility to farm area demanding fish species on a relatively small ground surface and at relatively low cost, resulting in a substantial increased s production. Simultaneously investments as well as operation cost are reduced.
  • the plant may be used for farming a number of different fish species.
  • Water supply to the plant may be based on pumping or if available, in the case of farming in fresh water, water may o be supplied by gravity from rivers and/or lakes.
  • the fish farm according to the present invention is constructed preferably in concrete on site or as prefabricated concrete elements.
  • the farm design is evenly well suited for the use of other materials such as steel, and also a 5 combination of steel and concrete.
  • the drawing discloses in figure 1 a cross section of a fish farm according to the present invention and figure 2 discloses a smaller ground view of the fish farm disclosed in figure 1.
  • the basic fish farm comprises two outer walls 1 arranged parallel to and at a distance from one inner wall 2 all of which being secured to a concrete base 16, thereby establishing two elongated tanks being closed at both ends by end walls (not shown). Due to the stability of the walls a roof may 5 cover the entire building, resting on the walls.
  • the base 16 or floor may be horizontal or slightly inclined inwardly to the middle of each tank.
  • Each longitudinal tank is divided into cells by flow deviators 3, preferably in such a way that one deviator 3 is arranged at each corner of a square.
  • the deviators 3 constrict the corners of the square, each deviator 3 extending along the height of the walls.
  • the deviators 3 provide space for feeding, regulation of the water level 6, instrumentation etc.
  • the deviators 3 may be plane walls extending from the base 16 to the top of the walls and facing the center of the cell. Furthermore the deviators 3 may have a step like surface or even be concave.
  • each cell In the centre of each cell a vertical outlet pipe 5 is extending, being provided with perforations guiding the water through a pipe 7 below the cell to a collector 8, to which corresponding pipes 7 from all cells is connected.
  • Water is supplied to the tank through one or possibly more supply pipes 4 in each cell, having equally directed perforations along the height, thereby maintaining a directed water flow along the walls and the deviators 3 creating a spiral ending up in the outlet pipe 5.
  • the supply pipes 4 direct the water flow in alternating directions in adjacent cells, the water thereby flowing in the same direction between two cells where typically no wall is located but where partition walls 13 may be inserted, in the form of a grid of any kind or even a closed wall.
  • the partition walls 13 may .be inserted or removed between the opposite deviators 3 according to the needs present, thereby closing some of the cells completely or only partially with partition walls 13 in the shape of grids. Closed partition walls 13 also provide a possibility to establish infection bars when sealingly closed.
  • Further outer walls 17 may be erected parallel with and at a distance from the outer walls 1, thereby establishing a transportation channel 11. In case a further farm building is constructed parallel to the first, the distance between the opposed outer walls establish a channel 11.
  • Working platforms 18 are extending in the longitudinal direction above the center wall 2 and flow deviators, adapted for inspection, maintenance and transportation, which platforms 18 giving access to gangways extending above the cells, carried by frame work, possibly connected with the outlet pipe 5.
  • Gates or closures 19 provide connection from each cell through the center wall 2 as well as to the outer channels 11, providing excellent possibilities for grading fish as well as transporting fish between individual cells.
  • a common water supply channel 15 is arranged above the center wall 2, for water supply to the inlet pipes 4. Valves s control in a known manner the water flow supply from the channel 15 to the inlet pipes 4 as well as downstreams through the water flow circuit.
  • the channel 15 may be connected to a purifying means, thereby recycling water from the channel 8.
  • Each cell furthermore contains a sludge pot 14 situated o in the centre of the cell in the base 16 around the outlet pipe
  • the length of the cell wall tanks typically may be from s 3 to 20 meters or more, the height of the walls and thereby the water depth may be up to 4 meters.
  • the fish farm preferably is equipped with a central pneumatic (or otherwise) automatic feeding system comprising external silos and farm integrated components as dosing o equipment, screw conveyors, ejectors, blower and others.
  • the feed is distributed either on the surface in each cell or in the water in each cell.
  • the fish farm may be monitored and controlled by computer processors to ensure optimum conditions 5 in each individual cell and tank.
  • Supply of oxygen may be performed by means of diffusors arranged at specific places in the water flow. Emergency supply of oxygen is achieved with pipes or hoses secured to the tank wall near the tank floor, being activated by signals from oxygen sensors at the outlet of each tank.
  • Plants provided with roof may comprise continuously adjustable light in such a way that light control and light manipulation is possible.
  • the water supply needed for the farm may be pumped up from the sea, whereby pumps and pump stations being integrated in the farm itself. Additional installations provide the possibility for recirculation of substantial water amount using part of the water flow from the water outlet 8, supply air to this water and recirculate the water by pumping.
  • the farm also may contain installations making use of heated water possible.
  • Fish grading may be performed by means of the partition walls 13 between cells and/or between the cells and the transpor ⁇ tation channel 11. Fish to be slaughtered may be taken out s through the same transportation channel 11 from which the fish is guided into a special gutting chamber.
  • Grading preferably is accomplished also by grid partition walls 13 between the cells or between the cells and the transportation channels. Such grading also may use conveyors in o the transportation channels.
  • Shelves 10 may be arranged in the cells, extending from the walls 1, the partition walls 13 and the flow deviators 3 inwardly towards the centre of the cell, leaving an opening 12 around the outlet pipe 5, the opening preferably extending to the s middle wall 2.
  • the shelves 10 can be nets or even solid sheets having open or perforated portions. The vertical distance between the shelves 10 shall supply the fish sufficient space. The shelf height will vary depending on the species farmed.
  • the shelves 10 may be shaped in such a way that an open slot is left along the circumference between the shelf and the walls.
  • Each shelf 10 preferably comprise a number of shelf sections.
  • the surfaces of the shelves (10) may consist of perforated net, may be combinated with solid materials and/or open areas, consisting alternatively of solid materials with open areas.
  • the shelves 10 may be constructed in stainless steel, seawater resistant aluminium or another material having corre ⁇ sponding qualities, possibly in reduced qualities if used in fresh water.
  • a framework carries the shelves 10, which framework also is carrying a working platform or platforms extending above each cell.
  • the framework preferably may be interconnected pipes, being used as distributor for feed, oxygen etc. Furthermore the framework may be used for carrying equipment such as propulsion devices and current generators.
  • the opening 12 may vary up to a sector of 180°.
  • the openings 12 may be arranged directly above each other or in another suitable manner.
  • the fish farm according to the present invention may be combined with known systems for fish farming, water supply and oxygenating such that one or more of these functions may be performed through the piping system, including the frame work.
