EVALUATION OF PACIFIC SALMON SPAWNING ESCAPEMENT PARAMETERS FOR THE RIVER BASINS OF NORTH-EAST KAMCHATKA
The article is the second part in a seria, devoted to figure out parameters of Pacific salmon escapement for spawning to the rivers of Kamchatka regiоn. In the first article we provided analysis for the rivers within the Petropavlovsk-Commander fisheries subzone in the south-east part of Kamchatka peninsula (Feldman et al., 2016). In this article we suggest parameters for Pacific salmon spawning escapement for the rivers of Karaginsky and Olyutorsky Gulfs, embracing the north-east part of the peninsula (the Karaginskaya fishery subzone). Similar article will be provided concerning the rivers of the west coast of Kamchatka. It is important to know the escapement to manage fisheries resource and work out logistics of fishery management. In mentioned seria we for the first time evaluated landmarks for spawning escapement for most part of Pacific salmon stocks of Kamchatka region. Models of the type stock-recruitment (reproduction curves) are used in the method for setting the fisheries landmarks. The method is based on obtaining data about stock and recruitment from general model for each certain species of Pacific salmon in a certain part of Kamchatka region with later splitting them into individual models for specific populations.
