DECREASING OF THE PINK SALMON (ONCORHYNCHUS GORBUSCHA) ABUNDANCE IN SAKHALIN-KURIL REGION AS CONSEQUENCE OF EXTREME ENVIRONMENTAL FACTORS IMPACT

Известия ТИНРО, 2018
The pink salmon abundance dynamics is considered for Sakhalin-Kuril region in 2007–2016. The year-classes of pink salmon originated from Iturup Island and four areas of eastern Sakhalin became weaker if they were affected by typhoons during their ...
