It is essential to formulate artificial diets for Cyclina sinensis to satisfy the requirements of industrial aquaculture. We evaluated the effects of different dietary sources on the growth, survival, nutritional components, digestive performance and nonspecific immunity of C. sinensis. The diets of the three experimental groups were as follows: natural bait (control group, CG), fermented Enteromorpha prolifea (EP) compound diet (Diet #1), and fermented Pyropia yezoensis (PY) compound diet (Diet #2). Feeding these diets did not affect the individuals' final weight, specific growth rate and survival rate. The total amino acid and total monounsaturated fatty acid of individuals fed with Diet #1 were significantly higher than those provided with the other diets (p < 0.05). There were no significant differences in the activities of α-amylase, lipase, trypsin, total superoxide dismutase, lysozyme and acid phosphatase in the clam fed with different diets. In conclusion, the two fermented seaweed compound diets prepared herein can replace natural bait and meet the growth and developmental needs of C. sinensis. The fermented EP compound diet can improve the nutritional quality of the clam. This study lays a preliminary foundation for developing new artificial diets for clams and elucidates the further utilization of low-value seaweed resources.

不同饲料来源对蛤蜊（Cyclina sinensis）生长、存活、生化成分和生理代谢的影响

为满足工业化水产养殖的需要，必须制定中华鲟人工日粮。我们评估了不同膳食来源对中华鳖的生长、存活、营养成分、消化性能和非特异性免疫的影响。三个实验组的日粮如下：天然诱饵（对照组，CG）、发酵浒苔（EP）复合日粮（日粮#1）、发酵条斑鱼（PY）复合饮食（饮食＃2）。喂养这些饮食不会影响个体的最终体重、比生长率和存活率。饲喂饮食#1 的个体的总氨基酸和总单不饱和脂肪酸显着高于饲喂其他饮食的个体（p  < 0.05）。饲喂不同日粮的蛤蜊的α-淀粉酶、脂肪酶、胰蛋白酶、总超氧化物歧化酶、溶菌酶和酸性磷酸酶的活性没有显着差异。综上所述，本文制备的两种海藻发酵复合日粮可替代天然饵料，满足中华鲟生长发育的需要。. 发酵EP复合饲料可以提高蛤蜊的营养品质。本研究为开发新的蛤蜊人工饲料奠定了初步基础，阐明了低价值海藻资源的进一步利用。
