梭子蟹全人工工厂化育苗技术

Technique of Artificial Industrial Seed Rearing of the Crab Portunes trituberculatus

２０００年笔者在日照市水产研究所利用１４５０ｍ３水体进行梭子蟹全人工工厂化育苗生产，共出Ⅱ～Ⅲ期幼蟹５１２．７万只，创造了出苗量为３５００只／ｍ３、总产值为１５０多万元的直接经济效益，同时对幼体培育的密度进行了初步试验，结果表明：从Ｚ１至Ｍ期幼体培育密度１０～１５万／ｍ３为宜，Ｍ期以后密度以 ０．８～１．５万／ｍ３为宜。

In the water body whose volume was 1 450 m3,5 127 thousand juvenile crab of II to K stage was acquired the per unit output was 3 500 md. /m3, the total production value was above 1 500 thousand yuan. The experiment proved that ,the suitable density from zoea stage to megalopa was 100-150 thousand in /m3, after then that was 8-15 thousand in /m3
