- Abstract
Thus, using acoustic conditioning can achieve the purpose of attracting dispersed individual fish into a group through sound signals, to effectively control fish behavior, and enable the catching of fish with fishing gear. They documented that in the mainstream of the Three Gorges Reservoir and its tributary, despite differences in their morphometric characteristics and fish species, the two types of acoustic surveys (parallel and zigzag transects) yielded fully comparable results, i.e., fish density and size distribution estimates were statistically the same. Understanding fish migration patterns and habitat use is essential for fisheries management, as fish movement data provide knowledge of space-use patterns in geographic and/or environmental spaces and link home ranges and habitat selection. Consequently, knowledge of the temporal and spatial movement and habitat use of target fish species during key life history stages is critical for fish population/community management, aquatic ecosystem conservation, and health improvement.
