Background
Coilia ectenes commonly known as hairtail, mao Daoyu, hairtail, etc., belong to the genus Engraulis of the order Clycideales, engraulis. Coilia ectenes are migratory fishes which are usually living in the middle and upper water areas in the offshore, enter the river from the offshore in spring and summer each year, and reproduce in areas with slow water flow such as river branches or lakes. Because of higher economic value and stable fishing flood formation, coilia ectenes have long been one of the most important fishing types in the water areas downstream of the Yangtze river and the Yangtze river, coilia ectenes often inhabit estuaries and offshore shallow seas for ingestion, and mature coilia ectenes clusters trace into rivers in batches for spawning in the breeding season. The natural resources of coilia ectenes tend to be exhausted due to factors such as transitional fishing, environmental pollution, hydraulic engineering construction and the like, and are now rated as 'endangered' by the world natural protection agency (IUCN).
Coilia ectenes are paid attention to due to the characteristics of cultural species, but basic theoretical research on coilia ectenes is very little, the research strength and depth of coilia ectenes are increased, and a sampling method is very critical. In the past, the polyethylene net is used for capturing the polyethylene net in the whole pond, so that not only is the manpower and material resources consumed, but also the fish seeds are easily subjected to long-time stress anoxic choking, fish net scratch and the like. The invention discloses an intelligent fishing device, which is characterized in that a plurality of trapping factors are emitted by a trapper to trap fish, so that the fishing speed is increased, the working efficiency is improved, the device is transported in water, the survival rate of the fish is increased, the fish can escape for a sufficient time, the condition of excessive fishing is effectively prevented, sustainable development is realized, but a fish storage component contained in the device easily generates stress reaction to move around to strike against the side wall of the component to cause wall deformation or breakage when the fish is stored, thereby causing damage to the fish, and meanwhile, the leakage-proof component easily blocks the fish body when in operation to cause damage to scales, fins and the like of coilia ectenes.
