Novel trawl net capable of reducing incidental catches

Abstract

The invention discloses a novel trawl net capable of reducing incidental catches, and belongs to the technical field of aquatic product catching. The novel trawl net comprises a netting, a fish attractor, a fish net bag and a shrimp net bag; the end of the left side of the netting is connected with a framework, the fish net bag is connected to the right side of the netting, the shrimp net bag is connected to the lower portion of the fish net bag, the fish net bag is internally provided with at least two sieve plates, and an escaping window is formed in the end of the right side of the fish netbag. By means of the novel trawl net, the incidental catches can be effectively sieved, and discharged to the outside of the netting, and the temporary raising density of the catches is lowered whilecatching of the incidental catches is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of aquatic fishing, and in particular relates to a novel trawl net for reducing by-catch. Background technique [0002] Trawling is an important operation method in my country's fishery production. The trawling operation area is large and the catch is large. Therefore, the marine organisms caught in the sea area where the trawling net passes are collected in the net regardless of the type and size. The process of sorting and storing fish catches requires a lot of labor and hours, which will increase operating costs, slow down the rhythm of catch circulation and market, and affect profits. [0003] At present, various countries in the world have carried out fruitful selective research on the characteristics of their own trawl fisheries and the main catch objects, and achieved relatively satisfactory results. However, many practical problems have been reflected in the process of promotion and application, which...

Problems solved by technology

[0002] Trawling is an important operation method in my country's fishery production. The trawling operation area is large and the catch is large. Therefore, the marine organisms caught in the sea area where the trawling net passes are collected in the net regardless of the type and size. Sorting and storing the catches requires a lot of labor and hours, which will increase the operating cost, slow down the circulation of catches and affect the income.

[0003] At present, countries around the world have carried out fruitful selective research on the characteristics of their trawl fisheries and the main catch objects, and achieved relatively satisfactory results. However, many practical problems have been reflected in the process of promotion and application, which need to be further improved and improved.
