Abstract Excerpt:
In the eastern region on the Okhotsk side of Hokkaido, the Kitami Salmon Enhancement Program Association produces and releases a total of approximately 180 million chum salmon fry every year. In the last 10 years, 6,893–19,144 thousand, with a mean of 12,224 thousand, chum salmon returned to this region; this quantity is equivalent to 33–48% of total return of chum salmon in Hokkaido and 28–42% in Japan. The number of chum salmon returning to the Kitami region peaked from 2003–2013 but has declined significantly since 2014. In Hokkaido, non-profit private salmon enhancement program associations established in nine regions produce and release juvenile chum salmon (Miyakoshi et al. 2013). The operating expenses of the enhancement programs are collected from fishery production; however, the recent decline in salmon catches has made the operation of the salmon enhancement associations even more difficult.
