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)。
The contents of trace elements such as selenium, iron, manganese, copper, chromium, cadmium and lead in the liver, back muscle and egg of brood stockfish were analyzed. The results showed that the contents of selenium and iron in liver of broiler flounder were significantly higher than those of broodstock (P <0.05), copper content was significantly lower than that of broodstock (P <0.05), and no significant difference was observed among other elements (P> 0.05). The content of selenium and manganese in the deaf muscle of wild brown flounder was significantly higher than that of the brood stock (P <0.05), and the contents of other elements remained the same (P> 0.05) The contents of selenium, iron and manganese in eggs were significantly higher than that of broodstock (P <0.05), and the content of selenium was about 1.7 times that of broodstock, the content of iron was 2.0 times that of broodstock, and the content of manganese was culture Broodstock 2.8 times. The content of cadmium in broodstock cultured broodstock was 78% higher than that in wild broodstock (P <0.05). The contents of copper, cadmium and lead in two kinds of brood roe did not show significant difference (P> 0.05).
