Actual and potential effects of introduced marine organisms in Norwegian waters, including Svalbard Research report 2001-1 Directorate for Nature Management Comments: In the 1970s, Russia transferred substantial numbers of Pacific salmon (Oncorhyncus keta and O. gorbuscha) ova to the Kola Peninsula, situated close to the county of Finnmark in northern Norway, and juvenile fish were liberated into the sea. In the late 1970s and 1980s, Norwegian fishermen frequently caught Pacific salmon in commercial nets and adults were observed spawning in some rivers in Finnmark. The Norwegian catches decreased until it was reported in 1990 that no such salmon were found in Norwegian coastal waters or rivers. |
