Definitions

  • the present invention relates to an arrangement in an en ⁇ closure having flexible side walls, for fish breeding, and .5 being of the kind as stated in the introductory part of the following independent claim 1.
  • the actual enclosure consisting of a bag shaped fishing net material that is stretched and fastened to a floating frame in the water.
  • Said frame forms a catwalk or a work-place, or the actual frame may be constructed as buoyancy members supporting such a catwalk or work-place
  • a landing net is commonly used for catching one or a number of fishes at a time, depending on their size.
  • the structure of enclosures for breeding fish thus, has dis ⁇ advantages, both in connection with catching the fish, and in 30 connection with pollution of the environment, and it is also difficult as regards maintenance, both as to cleaning the walls of the enclosure, and as to repair work when damaged.
  • Figure 1 shows the enclosure in a normal breeding state with a submersed- bottom
  • Figure la shows an alternative embodi- ment of the same
  • Figure 2 shows said enclosure with its bottom lifted for catching fish, or checking and/or repairing the bottom and/ or side walls of the enclosure, respectively, and a possible device for removing deposits.
  • FIG. 1 shows an enclosure 1 Itaving flexible side walls 2 made from a material that may, e.g. be a perfor ⁇ ated plastic sheet or a net having meshes, with the resulting openings in a plastic sheet or in a net are, preferably dimensioned to keep " undesirable parasites that may harm the fish out of the enclosure.
  • the upper side wall portion 2a of side walls 2 is secured to buoyancy members 3, e.g. in the shape of an upper floating frame 3a carrying/forming a catwalk/work place 4 which extends all along the upper side wall portion 2a of the enclosure around the entire top of enclosure 1.
  • buoyancy members 3 e.g. in the shape of an upper floating frame 3a carrying/forming a catwalk/work place 4 which extends all along the upper side wall portion 2a of the enclosure around the entire top of enclosure 1.
  • On said face 4 at least one fence 4a is provided on the edge qf said face toward the opening of said enclosure, and said ' fence may, if desired, be provided with a net to prevent the fish from leaping out of the enclosure.
  • the lower side wall portion 2b of enclosure 1 is secured to a liftable and lowerable frame 5 for lifting bottom la of en ⁇ closure 1 from its submersed position in the sea to an upper position in the water, inter alia to facilitate catching of breeding fish, and maintenance of the sheet/net material of said enclosure.
  • Lower liftable and lowerable frame 5 is connected with upper floating frame 3a via guide means 6 for cetering said frames 3a and 5 when lower frame 5 is lifted to its upper porition.
  • Said guide means 6 comprise guide stay members 6a which in the shown embodiment are secured to lowermost frame 5, and run through guide sleeves or the like in upper floating frame 3a.
  • Enclosure 1 and frames 3a and 5 are preferably rectangular, as shown in the drawing, and guide stay means 6a, and guide sleeves 6b are, preferably, placed in the corners of said frames.
  • Lower frame 5 comprises at least one, and preferably a number of water compartments. By pumping air into one or several water compartments it is possible to lift frame 5, and thus, the bottom la of said enclosure to a desired harvesting posit ⁇ ion, depending on the number of fishes in said enclosure, if desired up to upper frame 3a.
  • Bottom la of said enclosure preferably and as shown in the drawing, consists of a rigid plate which is inclined from the side walls 2 and frame 5 of enclosure 1 to its central portion la' being provided with a device 7 for removal of precipitates in the shape of faeces and excess feed. Due to the inclination of bottom plate la towards its central portion la 1 precip ⁇ itates will tend to collect in said central bottom portion la 1 , which may be provided with an opening, not shewn, which is connected with a suction hose (not shown) for precipitates that are preferably pumped to a purifying plant ashore, or to the purifying plant on a platform in connection with a group of enclosures 1.
  • the purified water can, thus, run out into the sea, whereas the separated more or less solid mass of precipitates is taken ashore for further treatment and for conversion into soil improving matter.
  • lower frame 5 may be provided with rinsing nozzles 8 directed towards the central portion of bottom la along the bottom surface. Precipitates will, thus, be washed towards central portion la of the bottom with its removal means 7.
  • rinsing nozzles 9 which are directed downward along the inside of side walls 2 of the enclosure 1 for washing down organisms or impurities that adhere to the_ insides of said side walls 2.
  • Said removal means 7, as shown in Figure 1, comprises a suction head 7a with a hose 7b extending along said bottom sur- face la to one of said guide stay means 6a, and extending up through said means to a not shown suction pump and conveyance to a purification plant.
  • Suction head 7a may, obviously, be connected with a hose 7b extending freely up to the top of said enclosure and to a suction pump and a purification plant.
  • Supply of fresh water in addition to the natural exchange of water through the- side walls of said enclosure, and if desired, supply of water having a desired temperature in relation to the surrounding water may be achieved in a manner known per se and will not be disclosed in more detail here.
  • said guide means 6 between said lower liftable and lowerable frame 5 and upper floating frame 3a consists of anchoring wires 10 having anchoring weights 11 at their lower end, or anchors, with said anchoring wires secured to the corners of said rectangular upper floating frame 3a.
  • Said anchoring wires extend through guides 12 in the corners to said liftable and lowerable frame 5, so that said frame 5 will be guided and kept in place by anchoring wires 10 wh.en it is lifted and lowered, respectively.
  • anchor ⁇ ing wires are attached to a frame 13 beneath said liftable and lowerable frame 5 in such a manner that said guide port ⁇ ions 10a of anchoring wire 10 extend in parallel from upper floating frame 3a to said frame 13 which may have the shape of a cross consisting of H-profiles that are welded together. From frame 13 to which anchoring wire 10 is secured said wires extend down to anchoring block 11 on the bottom of_- the sea.
  • guide means 6 with guide stay members 6a as shown in the first disclosed embodiment of Figure 1 is simplified.

Abstract

Enceinte (1) de pisciculture dont la partie supérieure (2a) de la paroi est fixée sur un cadre (3a) supérieur de portance ou de flottaison. La partie inférieure de la paroi latérale (2b) de l'enceinte (1) est fixée sur un cadre (5) pouvant être levé et abaissé afin de remonter le fond (1a) de ladite enceinte (1) depuis sa position immergée dans l'eau jusqu'à sa position supérieure dans l'eau, afin de faciliter la prise des poissons de culture, et l'entretien du matériau de feuille/filet de ladite enceinte. Des moyens de guidage (6) permettant de centrer les cadres comprennent des moyens de retenue de guidage fixés au cadre inférieur (5) et passant par des manchons de guidage (6b) dans ledit cadre supérieur de flottaison (3a). Le fond (1a) de ladite enceinte comporte une plaque rigide pourvue d'une partie centrale (1a') disposée plus bas que les parties périphériques, ceci afin de concentrer les sédiments qui seront évacués par un dispositif (7) vers une installation d'épuration.
