　　以缢蛏(Sinonovacula constricta)(A)、菲律宾蛤(Venerupis Philippinaram)仔(B)及自制配合饲料(C)作为饵料，分别研究了上述3种饵料对二龄管角螺(Hemifusus tuba Gmelin)生长、肝脏消化酶活性以及软体部营养成分的影响。结果表明：(1)鲜活饵料的投喂更有利于管角螺的生长和营养物质的累积，配合饲料的摄食效果较差，还需进一步的优化和完善；其特定生长率大小为：缢蛏组＞菲律宾蛤仔组＞配合饲料组，组间差异显著(P＜0.05)；(2)不同饵料的投喂对其肝脏消化酶活性的影响差异显著，在整个实验区间的胰蛋白酶活力的大小为：缢蛏组＞菲律宾蛤仔组＞配合饲料组，组间差异显著(P＜0.05)；配合饲料组的淀粉酶活力和脂肪酶活力先降后升，鲜活饵料组则较稳定；45 d 后配合饲料组的淀粉酶活力和脂肪酶活力皆显著高于鲜活饵料组的(P＜0.05)；表明管角螺在饥饿时，消化酶可能存在补偿性分泌，优先利用糖原和脂肪作为能源物质；(3)不同饵料对管角螺软体部的灰分和水分没有显著影响(P＞0.05)，鲜活饵料组的粗蛋白和粗脂肪含量皆显著高于配合饲料组(P＜0.05)。

Effects of three different diets, including Sinonovacula constricta(A), Meretrixie linnaeus(B) and for-mulated diet(C) on the growth,digestive enzymes activities and nutritional composition in sceral mass of two-year-old Hemifusus tuba Gmelin were studied. The results showed that:(1) the live feed was more conducive to H. tuba Gmelin growth and accumulation of nutritional, and the C feeding effects was more poorer and need further optimization and perfection;the SGR was significantly different among the experiment groups (P<0.05), group A>group B>group C;(2) the digestive enzymes activities in liver of H. tuba Gmelin were significantly different by feeding different diets. The specific activities of trypsin were significantly different among the experiment groups (P<0.05), group A>group B>group C;the specific activities of amylase and lipase were first decreased and then increased, but the live feed groups were much more stable; the specific activities of amylase and lipase were sig-nificantly higher than live feed groups (P<0.05), suggesting there might be compensatory secretion of digestive enzymes, and glucose and fat were utilized preferentially when H.tuba Gmelin was hungered; (3) no significant difference in moisture content and crude ash in visceral mass among the experiment groups (P>0.05), the crude protein and the crude fat content of live feed groups were significantly higher than that of the group C (P<0.05).
