Abstract
In order to evaluate three species of diatoms as the live food sources for rearing larvae of sea urchin, Strongylocentrotus intermedius, six different feed experiments were conducted for 35 days. We measured sizes, survival rates on elapsed day after hatching and required days of each larval stages of sea urchin in the different feeding experiments. Sizes of the larvae of sea urchin cultured with Isochrysis + Chaetoceros, Isochrysis, Chaetoceros and Pavlova were
북쪽말똥성게 유생기의 먹이효과를 알기 위하여 Chaetoceros calritrans, Pavlova lutheri 및 Isochrysis galbana의 3개 단독구와 이를 혼합 공급한(Chaetoceros + Pavlova, Pavlova + Isochrysis + Isochrysis + Chaetoceros) 3개 시험구 등 총 6개의 시험구에 대한 성장도, 생존율 및 발육 단계별 소요일수를 조사한 결과는 다음과 같다. 먹이 종류에 따른 유생의 성장은 8완기까지 Isochrysis+Chaetoceros의 혼합구, Isochrysis의 단독구 및 Chaetoceros의 단독구가 각각
