Large lake fixed net

Abstract

Provided is a large lake surface set net. A maze net is connected with the lower portion of a guide net shaped like a Chinese character 'ba', three beard nets shaped like an inverted Chinese character 'ba' are arranged below the maze net, and a circular beard net is arranged at the outlet of the last beard net shaped like the inverted Chinese character 'ba'; the outlet of the circular beard net is communicated with a fish collecting box body, and a movable partition net A is arranged between the circular beard net and the fish collecting box body; a silver carp sorting box body is connected with the lower portion of the fish collecting box body, and a movable partition net B is arranged between the fish collecting box body and the silver carp sorting box body. The large lake surface set net solves the problems that when net fishing is achieved by lots of labor, labor intensity is high, fishing efficiency is low and fresh and alive fish can not be fished all year round, belongs to a driven type fishing tool, saves lots of labor, and is large in fishing scale, high in fish catch, fresh in catch and good in quality. Fish is fished and sold all year round and appears on the market in a balanced mode.

Description

technical field [0001] The invention relates to a fishing device for fish farming, in particular to a large-scale lake surface fixed stretching net. Background technique [0002] At present, active fishing gear such as purse seines, trawls, and ground nets are generally used for large-scale lake aquaculture fishing, or combined fishing methods such as catch, fence, stab, and stretch. The above-mentioned fishing methods require a lot of manpower and material resources, and the labor intensity is high. Low, the fishing time is long and mostly concentrated in autumn and winter, and it will also cause certain damage to the catch, which is not conducive to long-distance transportation. However, existing passive fishing gears such as laying nets, inserting nets, and building nets have a small amount of catch, low quality catches, and problems such as continuous catches. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned similar technologies, th...

[0002] At present, active fishing gear such as purse seines, trawls, and ground nets are generally used for large-scale lake aquaculture fishing, or combined fishing methods such as catch, fence, stab, and stretch. The above-mentioned fishing methods require a lot of manpower and material resources, and the labor intensity is high. Low, the fishing time is long and mostly concentrated in autumn and winter, and it will also cause certain damage to the catch, which is not conducive to long-distance transportation

However, the existing passive fishing gear such as laying nets, inserting nets, and building nets has problems such as small catches, low quality catches, and inability to catch continuously.
