Abstract: Hydroacoustic survey has been one of the great tools in fish resource evaluation. This paper introduces the scheme design of hydroacoustic investigation and the estimation method of fish resources. Basing on the acoustic survey in the Three Georges Reservoir from the winter 2009, the correct-use methods of EY60 echo detection system and the application of Sonar5 analysis software are emphasized. In addition, the deficiency and application prospect of acoustic technology in river fish resource survey are discussed. The purpose is to provide technical reference for correctly using acoustic equipment and analysis software.

Key words: hydroacoustics; fish resource; survey; EY60; Sonar5
