摘要

In our study, stock identification of chum salmon was accomplished based on the scale structure criteria in the first year of growth according to techniques described by Davis et al. (1990) and Patton (1998). Fifteen variables were measured including: the number of sclerits for the first year of growth, the total radius of the first year growth zone, the total radius of the first year growth zone divided by two, the triplets of intersclerital distances from the first sclerit (six measures), and the retrospective triplets of intersclerital distances from the last winter sclerit of the first oceanic period of the growth (six measures).
