The Impact Mechanism of Inter-Basin Water Transfer on Fish Assemblages Was Revealed Using a Model of Terminal Reservoirs.

ABSTRACT: Understanding the impact mechanism of inter-basin water transfer projects (IBWTs) on fish assemblages is critical for conserving aquatic ecosystems and managing water transfer. However, direct evidence of the impact mechanism of IBWTs on fish assemblages is absent. Fish assemblages in newly built terminal reservoirs originate and assemble with diverted individuals through water transfer in IBWTs, providing a valuable model for mechanistic research. This study sampled fish quarterly using a combination net in three terminal reservoirs along the Eastern Route of the South-to-North Water Transfer Project (ER-SNWTP) from July 2021 to May 2022. We investigated assemblage composition and structure, calculated alpha and beta diversity indices, and analyzed the effects of environmental factors on
