摘    要:不同交配、越冬方式对河蟹育苗产量有着显著的影响,三年的生产实践表明:秋季室外土池交配的抱卵率、抱卵量明显高于水泥交配;秋季交配优于春季交配;室外土池自然越冬抱卵卵蟹的胚胎发育优于室外塑料大棚保温越冬的抱卵蟹。适宜的秋,春交配有利于河蟹多苗育苗,延长生长期,增加产量。

关 键 词:交配方式  越冬方式  河蟹  育苗

Abstract:Induced spawning and wintering for crab are directly related to the successful artificial breeding of mitten crab. According to the production experiments conducted by author from 1995 to 1997, over 90% of berrying rate and over 85 % of surviva1 rate of berried crab were obtained by inducing spawning in summer and wintering in outdoor soil pond. but 86% and 8l% in indoor concrete pond and wintering in plastic sheet shelf:over 85% of metamorphosis rate from Z1 to Z2 for former, but 45% for later. Suitable way of inducing spawning and Wintering of mitten crab can prolong the breeding period and increase productivity
Keywords:Induced spawning  Wintering of berried crab  Breeding of mitten crab
