测量了渤海湾隆线强蟹、日本关公蟹、三疣梭子蟹和日本蟳的头胸甲长( L1)、头胸甲宽( L2)、腹部长(L3)、腹部宽(L4)和体质量(m),采用相关分析、通径分析和逐步回归分析方法,分析了表型形态性状对体质量的作用效果。分析结果表明,隆线强蟹、日本关公蟹、三疣梭子蟹和日本蟳的各性状间均表现出极显著相关(P <0.01)。通径分析中,隆线强蟹和日本蟳均为头胸甲宽的直接作用最大(0.661、0.649),日本关公蟹和三疣梭子蟹为头胸甲长的直接作用最大(0.569、0.659)。应用逐步回归分析建立体质量与表型形态性状关系,隆线强蟹为ln m =-7.622+1.972ln L2+1.143ln L1-0.083 ln L4(r=0.940),日本关公蟹为ln m =-7.062+2.971ln L1(r=0.971),三疣梭子蟹为ln m =-8.058+2.238lnL1+0.660lnL2+0.129lnL4(r=0.986),日本蟳为lnm =-8.292+2.081lnL2+0.964lnL1(r=0.986),4种蟹类的回归效果均极显著( P<0.01)。
測量瞭渤海灣隆線彊蟹、日本關公蟹、三疣梭子蟹和日本蟳的頭胸甲長( L1)、頭胸甲寬( L2)、腹部長(L3)、腹部寬(L4)和體質量(m),採用相關分析、通徑分析和逐步迴歸分析方法,分析瞭錶型形態性狀對體質量的作用效果。分析結果錶明,隆線彊蟹、日本關公蟹、三疣梭子蟹和日本蟳的各性狀間均錶現齣極顯著相關(P <0.01)。通徑分析中,隆線彊蟹和日本蟳均為頭胸甲寬的直接作用最大(0.661、0.649),日本關公蟹和三疣梭子蟹為頭胸甲長的直接作用最大(0.569、0.659)。應用逐步迴歸分析建立體質量與錶型形態性狀關繫,隆線彊蟹為ln m =-7.622+1.972ln L2+1.143ln L1-0.083 ln L4(r=0.940),日本關公蟹為ln m =-7.062+2.971ln L1(r=0.971),三疣梭子蟹為ln m =-8.058+2.238lnL1+0.660lnL2+0.129lnL4(r=0.986),日本蟳為lnm =-8.292+2.081lnL2+0.964lnL1(r=0.986),4種蟹類的迴歸效果均極顯著( P<0.01)。

The present study describes the correlation among carapace length (L1 ) ,carapace width (L2 ) , abdomen length (L3 ) ,abdomen width (L4 ) and body weight (m) of 4 species of crab caught from June 2008 to May 2009 in Bohai Bay with the methods of path analysis and step regression .The results showed that the correlation between the morphometric traits of each species of crab was significant (P <0 .01) , and the lnL2 had the most direct effect on ln m in Eucrate crenata and Portunus trituberculatus ,the direct path coefficient is 0 .661 and 0 .649 ,respectively ,while in Dorippe japonica and Charybdis japonica ,the most direct effect on lnm was is LnL1 ,the direct path coefficient was 0 .569 and 0 .659 ,respectively .And the equation of E .crenata lnm= -7 .622 +1 .972lnL2 +1 .143lnL1 -0 .083lnL4 (r=0 .940) ,D .japonica lnm= -7 .062+ 2 .971lnL1 (r= 0 .971) , P . trituberculatus Lnm= -8 .058+ 2 .238lnL1 + 0 .660lnL2 +0 .129lnL4(r=0 .986) ,C .japonica lnm= -8 .292+2 .081lnL2 +0 .964lnL1 (r=0 .986)were established using the stepwise regression method .
