CRITICAL REMARKS TO PUBLICATIONS ON REPRODUCTION OF PACIFIC SALMONS IN THE RIVERS OF NORTHERN SAKHALIN ISLAND

Results of long-term studies of pink salmon reproduction (spawners run to the rivers, fry downstream migration and adults returns, their survival during the freshwater and marine periods) are widely presented for southern Sakhalin and southern Kuril Islands but were not published until nowadays for northern Sakhalin because of many uncertainties in the data. New series of scientific articles published by A.A. Zhivoglyadov with co-authors pretends to fill this gap, but they content a lot of errors and inaccuracies, so both presented data and conclusions should be considered very carefully.
