将壳长6．60±0．03mm的西施舌稚贝随机分为3组，每组投喂不同饵料，分别为藻类（XZ组）、配合饲料（XL组）和藻类与配合饲料的混合饵料（XH组），各设3个平行，20d后测定各组稚贝生长指标、消化酶活性以研究不同饵料对稚贝生长、消化功能的影响。结果：西施舌成活率在88．2％-96．6％。稚贝壳长增量各组间差异显著（P〈0．05），壳长平均增量XH组〉XZ组〉XL组。不同饵料组对西施舌体重影响不显著（P〉0．05）。不同饵料对西施舌稚贝蛋白酶、淀粉酶、纤维素酶和脂肪酶活性都有显著影响（P〈0．05）。蛋白酶和淀粉酶比活力XH组〉XL组〉XZ组；纤维素酶比活力XZ组〉XH组〉XL组；脂肪酶比活力xL组〉XH组〉XZ组。

A 20 days feeding trial was conducted to evaluate effect of different diets on growth performance and digestive en- zyme activities of juvenile Coelomactra antiquate. The juveniles 6. 60±0. 03mm were fed with Algae （Group_XZ） , formu- lated diet （ Group_ XL） ,and Group _XH was fed with Algae and formulated diet. The results showed： The survival rate of the juvenile C. antiquata was between 88.2% and 96. 6% in the treatments. The increment of shell length were found to be significantly different （ P 〈 0. 05 ） among the three groups, and Group _XH 〉 Group_XZ 〉 Group_ XL. The increment of weight were found to be not significantly different （ P 〉 0. 05 ） among the three groups, proteinase activities,amylase activi- ties,eelluase activities,lipase activities was were found to be significantly different （ P 〈 0. 05 ） among the three groups. The tendency of proteinase activities and amylase activities was Group _XH 〉 Group_ XL 〉 Group XZ; The tendency of celluase activities was Group XZ 〉 Group _XH 〉 Group_ XL ; The tendency of lipase activities was Group_ XL 〉 Group _XH 〉 Group_XZ.
