Studies on the Stock of Hokkaido Herring

IV Appearance of young Herrings along the Coast of North-eastern Hondo correlated with the Production of the Plentiful Year-classes along the Western Coast of Hokkaido

Abstract

Young herrings were taken along the coast of Iwate-ken and Miyagi-ken by set nets exclusively in spring of the year (or, rarely, of the two successive years) following that when unusually plentiful year-classes were produced along the western coast of Hokkaido. In spring following that of the usual production of year-classes along the coast of the latter coast no catch of herring along the former is recorded.
