摘　　要：分析了野生与人工养殖褐牙鲆亲鱼肝脏、背肌及卵中硒、铁、锰、铜、铬、镉和铅等微量元素的含量。结果表明,野生褐牙鲆亲鱼肝脏中硒、铁含量均显著高于养殖亲鱼(P<0.05),铜含量则显著低于养殖亲鱼(P<0.05),其他各元素间均未见显著差异(P>0.05);野生褐牙鲆亲鱼背肌中除硒和锰的含量显著高于养殖亲鱼外(P<0.05),其他各元素含量均基本保持恒定(P>0.05);野生褐牙鲆亲鱼卵中硒、铁和锰的含量均显著高于养殖亲鱼(P<0.05),其中硒的含量约为养殖亲鱼的1.7倍,铁的含量约为养殖亲鱼的2.0倍,而锰含量则为养殖亲鱼的2.8倍。养殖褐牙鲆亲鱼卵中镉含量与野生亲鱼相比高出78%(P<0.05)。两种亲鱼卵中铜、镉、铅3种重金属含量均未见显著差异(P>0.05)。A comparison analysis of trace elements in muscle, liver and eggs of wild and cultured Paralichthys olivaceus broodstock was conducted. The results showed that contents of Se and Fe were significantly higher, while Cu was significantly lower in liver of wild fish than cultured fish （P0.05）,and no difference was found for other elements （P0.05）; Contents of both Se and Mn in dorsal muscle of wild fish were statistically higher than those of cultured fish （P0.05）, while no change was found for other elements （P0.05）; Se, Fe and Mn content in eggs of wild fish was about 1.7, 2.0 and 2.8 times higher than those of cultured fish, respectively （P0.05）.Cr content in eggs of cultured fish was 1.78 times higher than those of wild fish, however, no differences were found for Cu, Cd and Pb contents in eggs of wild and cultured P. olivaceus broodstock.
