Abstract
To know the variation in the growth of the sea urchin, Pseudocentrotus depressus according to their localities, three different populations including the culture populations, the released populations, and the wild populations were investigated using the cluster analysis. For this purpose, pigment banding pattern on the genital plate was used as an age character. The population composed of the same year class was born between September 25th and October 5th every year. The population of 9 to 10 months old had no
분흥성게의 양식군, 방류군, 야생군에 대하여 생식판에 나타나는 색소대를 연륜으로 하여, cluster 분석에 의한 지역별 성장 양상을 파악하고, 군집상호의 성장특성을 비교검토 하였다. 1. 단일연급군으로 구성된 양식군은 매년 9월 25일에서 10월 5일 사이에 출생한 개체들로서, 약 9-10개월후의 표본군에서는
