摘　　要：根据2013年4月—2014年2月厚壳贻贝Ⅰ龄个体跟踪调查和2013年8—12月Ⅱ龄个体取样调查数据,利用Taylor公式、线性函数和Von Bertalanffy生长方程对中街山列岛海域厚壳贻贝生物学特征及生长规律进行了分析。结果表明:雌雄样本间壳长、壳高、壳宽、体重、贝壳重和软组织湿重差异不显著;壳长与壳高、壳宽之间有极显著的线性正相关关系,壳长与体重、贝壳重、软组织湿重之间有极显著幂函数关系;壳长生长方程为Lt=87.48(1-e-0.348(t+0.913)),体重生长方程为Wt=79.51(1-e-0.348(t+0.913))3;8—10月是厚壳贻贝生长旺季,8月下旬为性成熟拐点,建议厚壳贻贝春季苗的最佳收获期为10月中旬。Mytilus coruscus is an economic mollusc and good object for artificial propagation andculture, but there are very few reports about its biological characteristics so far. Based on the dataof tracking survey of one-year-old M. coruscus from April 2013 to February 2014 and of samplingsurvey of two-year-old M. coruscus during August to December 2013, Taylor formula, linear func-tion and Von Bertalanffy growth equation were used to analyze their biological characteristics andgrowth patterns in the waters of Zhongjieshan Islands. The result showed that there were no obvi-ous differences in shell length, shell height, shell width, body weight, shell weight and wetweight of soft tissues between male and female individuals. There were significant positive linearcorrelations between shell length and shell height and shell width. Moreover, there were signifi-cant power function relationships between shell length and body weight, shell weight, and wetweight of soft tissues. The growth equations of shell length and body weight were as follows ： Lt =87.48 （ 1 -e-0.348（t＋0.913） ） and Wt = 79.51 （ 1 -e-0.348（t＋0.913） ） 3 respectively. The period between Au-gust and October was considered to be the rapid growth season, and inflection point of sexual ma-turity of M. coruscus was in late August. It was proposed that mid-October was the best harvestseason for spring seeding.
