【摘要】：對2008年~2009年渤海灣漁業(yè)資源調(diào)查的22種主要漁獲體長(叉長、頭胸甲長、頭胸甲寬、胴體長)和體質(zhì)量數(shù)據(jù)進(jìn)行統(tǒng)計(jì),并對各生物種類體長與體質(zhì)量關(guān)系進(jìn)行冪函數(shù)回歸。結(jié)果顯示,22種主要漁獲包括分屬4目、7科的9種魚類,8種蝦蟹類隸屬十足目下的6個(gè)科,4種軟體類屬于2個(gè)目、2個(gè)科,以及1種蝦蛄;22個(gè)種類體長與體質(zhì)量關(guān)系回歸的指數(shù)b介于1.271~3.316,主要集中在2.979附近,其中10種是等速生長,另10種是負(fù)異速生長,還有2種是正異速生長;除4種蝦外,其余種類的體長與體質(zhì)量回歸式的相關(guān)系數(shù)R2均超過0.81,冪函數(shù)對體長與體質(zhì)量數(shù)據(jù)的擬合效果較好。
[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.
