Abstract

Results of in situ testing of BioSonics DT-X and Didson hydroacustic systems set on migrating path to spawning grounds of adult sockeye salmon in the Ozernaya River are presented. Two million 374 thousand fishes was recognized and counted for the whole working period of the systems, including one million 276 thousand individuals registered by BioSonics DT-X echo-sounder and 1 million 98 thousand – by Didson imaging sonar. The data on the assessment of Pacific salmon escapement in the Ozernaya River allow to make recommendations on the use of the BioSonics DT-X and Didson hydroacustic systems as a tool for assessment of Pacific salmon escapement in rivers of Kamchatka.
