METHOD FOR CONSTRUCTING ECO-BRIDGE SYSTEM OF COMBINED MOVING WAY WITH FISH AND BENTHOS

摘要

Purpose: a fish pass system installation method has and is used for benthic one comprehensive ecological path and fish, is provided to simultaneously and independently transfer and migrates in light, seawater fish, demersal fishes and benthon. Construction: a fish pass system installation method has and is used for benthic one comprehensive ecological path and fish, as described below. A kind of fish pass system of one dual structure has a paths, and can migrate movement while light, seawater fish, demersal fishes and benthon. One concrete structure is formed to connect and assemble a sluice gate drainage unit and a sluice gate drainage unit. In conjunction with projection and an engagement groove, specifically composition is constituted respectively, in order to make that projection (160a, 160b) is combined to correspond to engagement groove (170a, 170b).
