三种不同生物饵料对曼氏无针乌贼繁殖能力的影响

The Effect of Three Different Biological Baits on Fecundity of Sepiella maindroni

摘要: 本文采用南美白对虾、泥鳅、沙蚕三种不同的生物饵料营养强化曼氏无针乌贼亲本，以养殖水体理化因子变化、亲本成活率、卵质量为指标进行分析。结果表明：投喂三种不同生物饵料养殖水体水环境理化因子变化差异不显著(P > 0.05)；采用南美白对虾营养强化的亲本成活率为85%显著高于另外两组投喂组(P < 0.05)；南美白对虾组、泥鳅组、沙蚕组的个体平均产卵量分别为650 ± 33粒、530 ± 21粒、570 ± 8粒。说明，南美白对虾作为曼氏无针乌贼亲本营养强化饵料，效果更佳。

Abstract: In this study, Sepiella maindroni parents were nutritively enhanced by using three kinds of live foods which are Litopenaeus vannamei, loach, and nereis. The indexes of the changes of physical and chemical elements of water, survival ratio of parents and egg quality were analyzed. The results showed that the physical and chemical factors among the three different groups feeding with different live foods were not significant differences (P > 0.05). But the survival ratio of parents in the groups feeding with L. vannamei was significantly higher than the other two groups (P < 0.05). Meanwhile, the mean spawn quantities of L. vannamei, loach and nereis were 650 ± 33, 530 ± 21, and 570 ± 8, respectively. In short, L. vannamei has a better effect as a kind of live food of nutrient enhancement of S. maindroni parents.
