Abstract
The invention discloses a fish trapping suspension net cage for different water flow layers. The fish trapping suspension net cage comprises a net cage body, a mounting shaft is fixedly connected to the middle positions of the inner walls of the two sides of an inner cavity of the net cage body, and a convolution vortex mechanism is fixedly connected to the middle position of the outer surface ofthe mounting shaft; partition nets are fixedly connected to the top and the bottom of the inner cavity of the net cage body and located at the two sides of the convolution vortex mechanism, bait mechanisms are fixedly connected to the top and the bottom of the inner cavity of the net cage body and at the sides, away from the convolution vortex mechanism, of the partition nets, and loading pocketsare fixedly connected to the outer walls of the two sides of the net cage; and an adjusting rope is movably connected to the outer surface of the convolution vortex mechanism, a floating positioning mechanism is fixedly connected to the middle of the top of the net cage body, and a wave regulating and controlling mechanism is movably connected to the end, away from the convolution vortex mechanism, of the adjusting rope. The invention relates to the technical field of fish trapping. By adjusting the floating volume of the net cage, positioning of the net cage at the water layers of different depths can be achieved, different types of fishes can be trapped conveniently, the application range is widened, and cost consumption is reduced.
Description
technical field [0001] The invention relates to the technical field of fish trapping, in particular to a suspended net cage for trapping fish in different water flow layers. Background technique [0002] Fishing nets are an indispensable fishing tool for fishery production. Coastal fishermen first used simple nets to fish on the seashore. Shallow sea fishing nets such as lift nets and stick nets appeared in the Ming Dynasty. After the Qing Dynasty, distant sea fishing nets appeared. Fishermen mostly fish with small-scale fishing gear. The main fishing gear used in fishery production are lifting nets, inflatable lifting nets, stick nets, push nets, arch pocket nets, ground nets, insertion nets, snatch nets, sticky nets, pull nets, flow nets, etc. Net, trawling, netting, spinning net, stretching net, fishing hook, clam-picking pole, fishing net, foil, river seine, rowing net, scooping net, calling net, hanging net, slipping foil net, crab pot, crab bucket Among them, pull net...
