摘要

To manage salmon internationally, stock identification is indispensable to determine ocean distributions and abundance. In Japan, tag release, scale pattern, parasites, genetic variation, and otolith mark are mainly used to estimate the geographical origin of salmon in the ocean. In collaboration with the North Pacific Rim countries, intensive salmon tagging experiments have been conducted on the high seas since 1956. Recovery information indicated ocean migration routes of major stocks of maturing sockeye, chum, pink, and coho salmon (Ogura 1994). However, the tagging information was insufficient to clarify the distribution and abundance of major salmon stocks throughout the entire ocean life including juvenile and overwintering periods.
