【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]:The body length (forked length, head chest armour width, carcass length) and body mass data of 22 main species of fishery resources in Bohai Bay from 2008 to 2009 were analyzed, and the power function regression was used to analyze the relationship between body length and body mass of each biological species. The results showed that 22 main species of fish, including 9 species of fish, 8 species of shrimp and crab belonging to 4 orders and 7 families, belong to 2 orders and 2 families, belonging to 6 families, 4 species of soft fish and 4 species of soft species belonging to Decapoda. The regression index b of the relationship between body length and body mass of 22 species was between 1.271 and 3.316, mainly concentrated in the vicinity of 2.979, in which 10 species grew at isokinetic rate, the other 10 species grew at a negative allometric rate, and 2 species grew at a positive rate, with the exception of 4 species of shrimps. The correlation coefficient R2 of the regression equation of body length and body mass of other species is more than 0.81.The power function has better fitting effect on body length and body mass data.
