| 摘要: |
| 在广西海洋研究所竹林盐场海水增养殖试验基地进行锯缘青蟹(Scylla serrata)育苗中后期(Z3~M)添加投喂螺旋藻和用鱼油强化过的丰年虫两种饵料补充营养实验。实验结果表明,添加螺旋藻可以降低青蟹育苗中期溞状幼体Z3~Z5的死亡率和缩短育苗周期;用鱼油强化丰年虫后再投喂蟹苗,可以降低Z5~M的死亡率;两种补充方法结合使用,可以明显降低青蟹育苗后期死亡率,缩短育苗周期。 |

| Abstract: |
| To determine nutritional value of different addition feeding for zoea stage of Scylla serrata (Z3~M), the dietary added Spirulina platensis and feeding the zoea stage with fish oil enriched shrimp were used. The research indicated that Spirulina platensis fed the larva with shrimp could reduce mortality from the zoea 3 stage to the zoea 5 stage, and cut the time of the growth cycle; The fish oil enriched shrimp fed the larva can reduce mortality from the zoea 5 stage to megalops; fish oil enrichment of shrimp fed the mud crab with Spirulina platensis not only decreased mortality, but also shorten the raise seedling period. |
