摘要
试验结果表明,4-5月和9-10月,水温22~27℃时,为硬壳蛤快速生长期;11月至翌年2月,水温8~15℃时,生长缓慢;5-6月硬壳蛤处于繁殖期间,生长也较为缓慢。硬壳蛤壳长和壳高的相关关系为y=1.8479x+0.5923;壳长和体质量的相关关系为y=0.0002x3.1174。
The growth of clam Mercenaria mercenaria were studied in different phases.The results showed that the clam grew rapidly from April to May and September to October at water temperature of 22~27 ℃;while the clams grew slowly from November to next February when the temperature was kept at 8～15 ℃.The clams grew slowly from May to June for propagation.The correlated equation between shell length and shell height was expressed as y=1.8479x+0.5923;the correlated equation between shell length and wet body weight y=...
