利用生物活饵料对中华绒螯蟹(Eirocheir sinensis H.Milne-Edwards)大棚育苗的研究

在全埋式无地沟无法吸污的育苗条件下,利用鲜活生物活饵料进行中华绒螯蟹(Eriocheur Sinensis)俗称河蟹的大棚育苗,配套生物饵料培养池50,000m2, 育苗水体1,680m3,平均每m3育苗水体培育出河蟹大眼幼体0.289kg。共育河蟹大眼幼体486kg,其中试验池为1,520m3水体;单位水体出苗量为0.314kg,对照池为160m3水体;单位水体出苗量为0.190kg。试验池比对照池每m3水体出苗量增产39.5%。

A Comparative Study of Genetic Variation between Chinese Mitten Crab Eriocheir Sinensis and Hepu Mitten Crab E.Hepuensis

Horizontal starch gel electrophoresis was used to investigate the biochemical genetic structure of Chinese mitten crab Eriocheir sinensis and Hepu mitten crab E.hepuensis. Sixteen putative enzyme-coding loci were examined for forty-nine Chinese mitten crabs and thirty-eight Hepu mitten crabs. Nine loci, AAT-1 *, AAT-2 *, G3PDH *, GPI *, IDHP-1 *, IDHP-2 *, MDH-1 *, MDH-2 * and PGM *, are polymorphic in Chinese mitten crab, and seven, AAT-1 *, AAT-2 *, GPI *, IDHP-1 *, MDH-1 *, MDH-2 * and PGM *, are polymorphic in Hepu mitten crab. The proportion of polymorphic loci and the expected heterozygosity are 0.562 5 and 0.080 3 for Chinese mitten crab, and 0.437 5 and 0.075 4 for Hepu mitten crab. The Nei’s genetic distance between two species is 0.002 4.
