Abstract

The invention discloses a method and system for determining a fish migration channel. The method includes determining the water environment parameter information of the target fish habitat according to the basic topographic data and hydrological data of the target fish habitat; Trace behavior characteristics and water environment parameter information to determine the movement trajectory of the target fish; use the cluster analysis method to cluster the movement trajectory to determine multiple potential migratory channels of the target fish; determine the weight of each potential migratory channel, use The weighted average method determines the final migration path of the target fish. The influencing factors considered by the method and system of the present invention are comprehensive and accurate, and the determined migration channel is obtained by quantitative calculation, so the accurate fish migration channel can be quickly obtained.

Description

technical field [0001] The invention discloses a method and a system for determining a fish migration channel, belonging to the technical field of environmental protection. Background technique [0002] Fish migration mainly includes reproductive migration, cable erbium migration and wintering migration. It is aimed at cold-water freshwater fish that live in the Yellow River all their lives. The reproductive migration is from the lower reaches and tributaries to the middle and upper reaches of the river to spawn; cable erbium migration. Occurs in fish groups that have ended their breeding season or are approaching sexual maturity. Fish take in and supplement the enormous energy consumed by reproductive migration and reproduction through sodium. A large amount of nutrients can be accumulated for growth, overwintering and gonad redevelopment; overwintering migration refers to when the temperature drops and affects the water temperature, fish often gather in groups in search of...
