Abstract: | Four-year summer observations have shown that G. takedai distribution in Salmonidae of Sakhalin is limited by the rivers entering the Aniva Bay. Maximum infection of pink salmon (Oncorhynchus gorbuscha) amounts to 70-100%, that of masu salmon (Oncorhynchus masou) to 9.0-45.6% and was recorded in September. Dynamics and possible ways of infection are discussed. |
