Farming enclosure saving much work for fish farmers when net cages (4a, 4b) in a plant at sea are to be exchanged and cleaned. In connection with a farming enclosure for fish or marine animals, comprising a supporting structure that is provided at the water surface (2a) and to which a net (4) is secured for forming one or more net cages (4a, 4b) forming one or more dwelling zones under water for the fish, means (5, 6, 7) are provided according to the invention, which serve to exchange net (4) while the fish dwells in said net cages (4a, 4b). In an embodiment of the invention a net reel (5) is used at each end of the structure. Said net reels (5) serve for alternating reeling in and reeling off net (4) along the area of the dwelling zones (4a, 4b) of the fish, at the same time as the net (4) is rinsed in the area of the net reels (5). In this manner clean net (4) for the cages (4a, 4b) is always stored and the cages can be exchanged without the fish (2b) having to be moved. To prevent that the net is pulled up to the surface (2a) in the areas where it forms net cages (4a, 4b) the structure comprises guide means (6) mounted on adjustable slides (7). The structure comprises a portion (1, 2) extending down into the sea in the net area to suppress wave movement and prevent foreign bodies and ice cold water from penetrating into the net cages (4a, 4b). |
