Abstract

Lee's phenomen is apparent in the first ring radii on the scales readings of 1-4 years old the red sea bream Pagrus major caught from the Western Wakasa Bay. The compositions of the first ring radii on the scales of the fishing season in spring (April-June) and autumn (September-November), increased in the mean first ring radius from spring to autumn and decreased from autumn to spring in the following year, and the percentage occurrences of small first ring radius increased with their ages. Based upon the regional differences in the first ring radius on the scale of 1 year old fish in the Tsushima Warm Current area, is it partly caused by their movement and migration toward the northern or southern area.
