摘　　要：采用4类营养型饲料(13种饲料原料和1种鲍用配合饲料)单一饲喂中间球海胆Strongylocentrotus interm edius稚胆(D=2.67±0.16 mm)110 d,测定其壳径和体重特定生长率、蛋白质消化率、总消化率及投饵系数。结果表明:4类营养型饲料的饲喂效果依次为鲍用配合饲料>青绿饲料>能量饲料>蛋白饲料;从稚胆壳径、体重特定生长率看,选择饲料原料时,青绿饲料中以紫菜、孔石莼为好,能量饲料中以麦麸为好,蛋白饲料中以虾粉为宜;稚胆对鲍用配合饲料的消化率最高,青绿饲料较高,蛋白饲料居中,能量饲料较低。饲喂14种饲料110 d,稚胆的成活率均在95%以上。Juvenile sea urchin Strongylocentrotus interrnedius （test diameter = 2.67 ± 0.16 mm） were fed 13 kinds of feedstuff and 1 formulated feed for 110 days to evaluate the effects of the different feedstuff on growth and digestibility. The test diameter, body weight, apparent protein digestibility, total apparent digestibility and feed conversion ratio were measured in the sea urchin. The results showed that the sea urchin fed the formulated feed had the best growth, followed by the energy feed, and the worst in the sea urchin fed the protein feed. For the vegetable feed, laver and sea lettuce Ulva lactuca were better, for energy feed, wheat bran better, and for protein feed, pea- nut powder better. Juvenile sea urchin had adapted for protein feed within 8 days. In 110 day feeding period, the juvenile sea urchin fed the 14 kinds feedstuff had survival rate of over 95%.
