摘要:

本试验以泥蚶(Tegillarca granosa)浮游幼虫、文蛤(Meretrix meretrix)浮游幼虫和菲律宾蛤仔(Ruditapes philippinarum)稚贝为对象,研究了微藻粉分别以0、50%和100%的比例替代鲜活微藻饵料(分别记为100%鲜活微藻组、50%微藻粉组和100%微藻粉组)对滩涂贝类规模化育苗的影响。 结果发现: 在泥蚶浮游幼虫的培育过程中,自第12天起,100%微藻粉组的壳长显著(p<0.05)低于50%微藻粉组和100%鲜活微藻组,而后两组之间无显著差异。在文蛤浮游幼虫的培育过程中,3组的壳长始终无显著差异。在菲律宾蛤仔稚贝的培育过程中,100%鲜活微藻组和50%微藻粉组的存活率显著高于100%微藻粉组,而前两组间无显著性差异。综上,在这3种滩涂贝类的人工规模化培育中,微藻粉可以部分或全部替代鲜活微藻使用,其中,50%替代比例表现出更优的适用性。

Abstract:

In this study, the effects of microalgal powder substitution for live microalgae at a ratio of 0, 50% and 100% (denoted as the 100% live microalgae group, 50% microalgae powder group, and 100% microalgae powder group, respectively) on large-scale nursery of mudflat shellfish were investigated using planktonic larvae of Tegillarca granosa and Meretrix meretrix, and juveniles of Ruditapes philippinarum. The results showed that during the cultivation of Tegillarca granosa planktonic larvae, starting from day 12, the shell length in the 100% microalgae powder group was significantly (p<0.05) lower than that in the 50% microalgae powder group and the 100% live microalgae group, with no significant difference between the latter two groups. No significant differences in shell length were observed among the three groups during the rearing of Meretrix meretrix planktonic larvae. For Ruditapes philippinarum juveniles, the survival rate of both the 100% live microalgae group and the 50% microalgae powder group was significantly higher than that of the 100% microalgae powder group, with no significant difference between the former two groups. In conclusion, microalgae powder is a viable substitute for live microalgae in the artificial large-scale rearing of these three mudflat shellfish species, with the 50% substitution ratio demonstrating better applicability.
