Follow-up scallop fishing net

Abstract

The invention discloses a follow-up scallop fishing net. The follow-up scallop fishing net comprises a net head, the net head is connected with a rigid net rack through a plurality of connecting chains distributed at equal intervals, a netting is arranged on the rigid net rack, a plurality of floaters distributed at equal intervals are further arranged on the top end face of the netting, a detachable sleigh plate is arranged at the bottom of the rigid net rack, the net head comprises a rigid net head frame, a detachable sleigh plate is also arranged at the bottom of the rigid net head frame, a water pressure plate is hinged to the front end of the rigid net head frame, two arc-shaped plates are further symmetrically arranged on the two sides of the rigid net head frame, and a plurality of angle adjusting holes distributed at equal intervals are formed in the arc-shaped plates; and the free end of the water pressure plate is provided with bolts which can be connected and fixed in the angle adjusting holes in a penetrating mode, a disturbance frame is further hinged to the rigid net head frame, a plurality of disturbance mechanisms are distributed on the disturbance frame at equal intervals, each disturbance mechanism comprises two supporting rods directly connected with the disturbance frame, and a rubber plate is arranged at the bottom ends of the supporting rods.

Description

technical field [0001] The invention relates to the fishing field of bottom-sowed scallops, in particular to a follow-up scallop fishing net. Background technique [0002] At present, in my country's North Yellow Sea area, the scallop aquaculture industry has developed rapidly and has become a key aquaculture industry in my country. Its production far exceeds that of other regions, with high scallop production and a wide farming area. In recent years, the scallop industry has been hit hard again, and its main product, the Ezo scallop, has died in large numbers, resulting in a loss of billions of yuan. Among them, the pros and cons of fishing technology directly affect the yield of scallops. Fishing nets have become an important tool for scallop farming. Whether their structure, material and performance are reasonable or not are directly related to the return rate, breakage rate, and Sediment content and trawling fuel consumption rate and the degree of damage to the seabed ...

AI Technical Summary

Problems solved by technology

When fishing with traditional nets, there are problems of scraping, crushing and injuring shellfish. The close contact between the bottom net of the nets and the seabed has caused "scraping and sweeping" damage to the seabed ecological environment. Scallop nets Fishing close to the ground causes sediment and other impurities to enter the net, which makes the scallops have a large amount of sediment and subsequent treatment is very difficult

At the same time, when fishing, the sliding friction between the bottom net and the seabed is very large, resulting in high drag resistance, serious damage to the seabed environment, and low fishing efficiency.
