ASPECTS OF BIOLOGY OF THE CHINESE MITTEN CRAB(ERIOCHEIR SINENSIS)REARED IN A POND

  • 摘要: 开展中华绒螯蟹(Eriocheirsinensis)生物学研究,对指导养殖具有重要意义.1993年6月20日购于上海市崇明县的仔蟹放养于湖北省保安湖渔场的一个试验塘(2330m2),每天投喂小杂鱼和螺蚌肉.在试验期间,河蟹成活率为18.6%.协方差分析表明,性别对各月体重与壳长、体重与壳宽及壳宽与壳长回归方程的截距和斜率均无显着影响(p0.05);但是,两性数据混合后的不同月份间回归方程的截距却有显着差异(p0.01).在每次取样时,雄蟹与雌蟹的壳长、壳宽及体重均不存在显着差异(p0.05),这表明雄蟹与雌蟹可能具有相同的生长率.在各次取样时统计的性比(雄∶雌)均无异于理论值1∶1(X2检验,p0.10).在九月中旬发现大部分雌蟹开始青春期蜕壳,在11月下旬雌蟹性成熟比例为88%,性成熟雌蟹壳长变幅为26.2-49.8mm,均值为34.1mm.
    Abstract: Some biological aspects of pond cultured postlarval Eriocheir sinensis were studied from June to November,1993. The survival of the experimental population was 18.6% as the crabs grew from 7.3 to 32.8 mm in mean carapace length. The relationships between body weight and carapace length or carapace width were described. Female crabs had the same growth rate as male crabs. The growth curve of carapace size or body weight was fitted well by a logistic equation. Sex ratio at each sampling time did not differ significantly from theoretic value of 1∶1(Chi square test,p0.10). Puberty molt of most females was observed in mid September,and the size of females at sexual maturity ranged from 26.2 to 49.8mm in carapace length,while the immature females were 26.0\41.2mm in carapace length.
