Abstract Excerpt:
All seven species of anadromous Pacific salmon listed in the NPAFC Convention—chum salmon, Oncorhynchus keta; coho salmon, O. kisutch; pink salmon, O. gorbuscha; sockeye salmon, O. nerka; Chinook salmon, O. Tshawytscha; cherry (masu) salmon, O. masou; and steelhead trout, O. mykiss—are caught every year by coastal fisheries in northern Japan. Of these, chum and pink salmon are most commonly caught; for example, chum and pink salmon comprised more than 97% (93.5% and 3.7% by weight, respectively) of the total catch in 2019, followed by masu salmon (2.7%) (Ministry of Agriculture, Forestry and Fisheries, Japan 2021). However, chum and pink salmon catches have either declined or been variable in recent years. This study assessed the status of current stocks of Japanese chum and pink salmon and the environmental anomalies that may be affecting salmon stocks.
