«Unfaithful» Pink salmon. Random or regularity?

Izvestiya TINRO, 2023
The reasons of «failed» forecasts for catch of pink salmon at the mainland coast of the Tatar Strait are analyzed. The classical «stock–recruitment» models produce regular errors in the forecasts of runs of pacific salmon under changing conditions of reproduction. To reduce the prediction errors, these models should include parameters of meteorological

The pink salmon invasion: a Norwegian perspective

Journal of Fish Biology, 2018
In the period 1956–1979, more than 220 million of pink salmon Oncorhynchus gorbuscha (Walbaum 1792) eggs from the southern part of Sakhalin Island in the Pacific Ocean were transported to the northwestern part of Russia (Gordeeva et al., 2015). The hatched fry were stocked to several rivers draining to the White Sea and Barents Sea,which is part of the
