Abstract

The invention discloses a fishing net special for acete chinensis. The fishing net comprises a net bag and net wings arranged on the two sides of the net bag, wherein net wings are connected to the two sides of the end of the net bag in a matched mode, the two net wings are symmetrically arranged, the end of any net wing is connected with at least one pull rope, and the end of each pull rope is connected with a fixed anchor; adjusting pieces are arranged on the edges of the two sides of the net wings and are of flexible structures, a first cavity and a second cavity are formed in each adjusting piece, each first cavity is filled with first gas, each second cavity is filled with second gas, the pressure of first gas is different from that of second gas, and the adjusting pieces are bent towards one side with low gas pressure; and at least one escape opening is formed in the outer side of the net bag and can be opened and closed.

Description

technical field [0001] The invention relates to a fishing net, in particular to a special fishing net for hairy shrimp. Background technique [0002] Hairy shrimp is a large zooplankton in the plankton group. It is widely distributed in the Indian Ocean, the Pacific Ocean and the Atlantic Ocean. It is also distributed along the coast of China. Hairy shrimp has important economic value and is an important fishery target. It is often used to produce shrimp skin and shrimp. Sauce and other products, in recent years, due to the impact of global climate change, there is an explosive trend of hairy shrimp appearing in some offshore areas. The explosive appearance of hairy shrimp will pose a huge threat to the safety of water areas. In order to avoid the occurrence of disasters, it is necessary to fish the explosive hairy shrimp. However, due to the extremely small size of the hairy shrimp, the technical parameters of the nets for fishing the hairy shrimp have very high requiremen...
