| 摘 要： | 对2008年-2009年渤海湾渔业资源调查的22种主要渔获体长（叉长、头胸甲长、头胸甲宽、胴体长）和体质量数据进行统计，并对各生物种类体长与体质量关系进行幂函数回归。结果显示，22种主要渔获包括分属4目、7科的9种鱼类，8种虾蟹类隶属十足目下的6个科，4种软体类属于2个目、2个科，以及1种虾蛄；22个种类体长与体质量关系回归的指数b介于1.271~3.316，主要集中在2.979附近，其中10种是等速生长，另10种是负异速生长，还有2种是正异速生长；除4种虾外，其余种类的体长与体质量回归式的相关系数R2均超过0.81，幂函数对体长与体质量数据的拟合效果较好。

| Abstract: | We describes the relationships between length（fork length, carapace length, carapace width and carcass length） and weight for 22 species of fishing resources caught during 2008~2009 in Bohai Bay and conducted a regression analysis of power function. A total of 4 478 individuals belong to 8 order and 16 families. The value of the exponent b in the length-weight relationship ranged from 1.271 to 3.316 and was mainly about 2.979. The t-test indicates that 10 species of isometric growth pattern, 10 species were in negative algometry and 2 species were in positive allometry. The R2 of length-weight of all species except 4 were larger than 0.81. The present length-weight key for 22 species of fishing resources is a valuable tool for fishery managers. |
