PCT No. PCT/SE85/00457 Sec. 371 Date Jul. 18, 1986 Sec. 102(e) Date Jul. 18, 1986 PCT Filed Nov. 14, 1985 PCT Pub. No. WO86/03097 PCT Pub. Date Jun. 5, 1986.A device for breeding fish and the like in open sea or lake in at least a netted bag (12), which at its upper part is supported by a pontoon (11), the depth position of which is variable. The purpose is to provide a breeding device which on one hand allows an upper cover also for very big bags, and on the other hand can be boarded also by bigger ships and independent of the wind conditions, and furthermore is designed thus that the taking up of fish can be carried out in simple way without bigger manual work. These tasks have been solved thereby that at the side of the pontoon (11) facing away from the netted bag (12) there is arranged a stand (18) which is tapering in the direction upwards for supporting a freely rotatable platform (23), to which a boarding gangway (24) is articulatedly connected, and that a sinker (16) having water as ballast is arranged at the lower end of the netted bag (12), which sinker and thereby the bottom (14) of the netted bag (12) is liftable to the water surface by blowing the tanks of the sinker. |
