Trawl survey of Pacific salmon on the R/V “Professor Kaganovsky” in the northwestern part of the Pacific Ocean (May-July 2018)
Abstract
Trawl survey was performed in the Pacific waters of the Kuril Islands and in open waters of the Pacific Ocean during the summer of 2018. The abundance and biomass of Pacific salmons in the period of their pre-anadromous migrations to the rivers of the Okhotsk Sea basin were surveyed in the upper epipelagic zone, and the main concentrations of the pink salmon producers were outlined. Data on spatial distribution, density, biological state of other mass fish species in the northwestern Pacific were obtained. Estimates of the abundance and biomass of migrating pink salmon on an area of more than 1 million km2 showed record results of 1.1 billion individuals and 913 thousand tons, respectively.
