| 用人工饲料:CAR、ARA、ARA2、DHA、CD和活饵:蓝藻粉(Spirulina)、中肋骨条藻(Skeletonemacostatum)、扁藻(Tetraselmischui)和卤虫(Artemia)分别在取自实验室供水系统和自然海区的海水中喂养印度对虾(Penaeusindicus)幼体。结果表明,投喂鲜活饵的印度对虾幼体,在取自实验室供水系统的海水中,平均成活率是55%,在取自自然海区的海水中,平均成活率是71.67%,从PZ1期变态到PL1期所需的时间都是9d;投喂人工饲料的印度对虾幼体,在取自实验室供水系统的海水中,实验至第2天后全部死亡,在取自自然海区的海水中,能够从PZ1期变态到PL1期,所需的时间是13d,平均成活率5.67%~39.00%,说明海水影响投喂人工饲料的印度对虾幼体的存活,藻类活饵有助于对虾幼体在不同类型海水中存活和生长。 |

| Abstract: |
| P.indicus larvae rearing trial was conducted by using artificial foods:CAR,ARA,ARA2,DHA,CD and live foods:Spirulina powder, Skeletonema costatum,Tetraselmis chuii in the seawater from lab water supply system and the sea.The larvae on live foods could acquire a survival of 55% in seawater from lab water supply system and a survival of 71.67% in seawater from the sea,and larvae metamorphosis from PZ1 to PL1 covered 9 days.When fed with artificial foods,the larvae reared in seawater from lab water supply system died in the second day,however,the larvae in seawater from the sea could survive from PZ1 to PL1 at a duration of 13 days with an average survival from 5.67% to 39.00%.The results showed that seawater had some impacts on the survival of P indicus fed on artificial foods,and microalgae were helpful to the larvae for their coping with different sorts of rearing seawater. |
