摘要
本文报导了对青蛤生长的观察和研究，作者描述了青蛤壳长与壳高的关系；壳长和体重的关系；体重（Ｗ·ｇ）和壳长（Ｌ·ｃｍ）的关系式为Ｗ＝０．２８１６×Ｌ￣（３．０６２）；青蛤生长７—１１月快，１—３月几乎不生长；青蛤生长与潮位关系是低潮位快，高潮位慢。此外还研究了水流、底质、放养密度和个体大小等因子对青蛤生长的影响。
Primary research on the growth of larval and adult clam Cyclina sinensis was carried out in recent years.(1) The relationship between clam weight (W) in gm and shell lenght (L) in cm can be expressed by the equation:W=0.2816L￣(3.062).(2) From July to November the clam grew faster,but there was a growth dormancy from January to March. (3) Growth rates of clams in different zones were different clam grew faster in low tidal zone than those in high tidal zone. We also investigated the effects of water current,substrates,stocking density and clam size on growth rate.
