Abstract

The invention discloses a fish migration channel determination method and system. The method comprises the following steps: determining water environment parameter information of a target fish habitat according to basic topographic data and hydrological data of the target fish habitat; determining a motion track of the target fish in combination with the swimming ability of the target fish, the upstream behavior characteristics and the water environment parameter information; clustering the motion trails by using a clustering analysis method, and determining a plurality of potential migration channels of the target fish; and determining the weight of each potential migration channel, and determining a final migration channel of the target fish by using a weighted average method. According to the method and the system, the considered influence factors are comprehensive and accurate, and the determined migration channel is obtained through quantitative calculation, so that 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, erbium migration and overwintering migration. For cold-water freshwater fish that live in the Yellow River all their lives, their reproductive migration is from the downstream and tributaries to the middle and upper reaches of the river to spawn; erbium migration Occurs in fish schools that have ended their reproductive period or are close to sexual maturity. Fish absorb and replenish the huge energy consumed by reproductive migration and reproduction through erbium erbium, and erbium migration can also restore fish physical fitness, enhance physical fitness, and It can accumulate a large amount of nutrients for growth, overwintering and redevelopment of gonads; overwintering migration means that when the temperature drop...
