Biological characteristics of Pacific salmon spawners of the Paramushir Island and Shumshu Island in 2021

Abstract

   The purpose of these studies is to obtaining up-to-date information on the dynamics of spawning migration and the quality indicators of Pacific salmon on the Paramushir and Shumshu Islands (Northern Kuril Islands).
   Methods used: the work was carried out in accordance with the methods generally accepted in fisheries research.
   Scientific originality: for the first time in the last decade, data were collected on the dynamics of anadromous migration and on the biological parameters of the Pacific salmon of the Northern Kuriles.
   Result: up-to-date information on the timing of spawning migration and quality indicators of pacific salmon of the Northern Kuril Islands in 2021 is presented. Information about the temporal structure of the spawning stream has been obtained.
   Practical significance: the results will be used in the preparation of materials substantiating the forecasted volumes of pacific salmon catches in subsequent years, as well as in regulating the fishing of pacific salmon in the Northern Kuril Islands.
