人工饲料和活饵喂养的印度对虾(Penaeus indicus)幼体的存活与生长

用人工饲料：ＣＡＲ、ＡＲＡ、ＡＲＡ、ＡＲＡ２、ＤＨＡ、ＣＤ和活饵；蓝藻粉（Ｓｐｉｒｕｌｉｎａ）、中肋骨条藻（Ｓｋｅｌｅｔｏｍｅｍａｃｏｓｔａｔｕｍ）、扁藻（Ｔｅｔｒａｓｅｌｍｉｓｃｈｕｉｉ）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（Ｐｅｎａｅｕｓｉｄｕｃｕｓ）幼体。结果表明，投喂鲜活铒的印度对虾幼体，在取自实室供水系统的海水中，平均成活率是５５％，在取自自然海

The Survival and Growth of Penaeus indicus Larvae Fed on Artificial and Live Foods

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.
