【摘要】 分别测定了新疆红雁热电养鱼场罗非鱼、淡水白鲳及鲤鱼的鳃、肝、肾、肌肉等部位中铁、铜、锌、铅、镉、铬、镍、砷等重金属蓄积量。结果表明,藻类沉积的重金属是鱼体重金属蓄积的主要来源;重金属主要蓄积于三种鱼的鳃、肝、肾等器官组织,肌肉重金属蓄积量明显低于鳃、肝、肾部位的蓄积量;热带鱼种与鲤鱼重金属解毒机制差异明显,冬季鲤鱼内源性重金属解毒能力明显劣于热带鱼种罗非鱼和淡水白鲳,重金属向肌肉转运加快,是鲤鱼肌肉重金属蓄积量有所增加的原因。更多还原

【Abstract】 Cyprinus carpio, Colossoma brachypomum and Tilapia nilotica were collected from fishpond of Hong Yan Company in Urumqi. Contents of heavy metal were measured for gill-liver, kidney and muscle of the fish studied. It was found that the accumulation of heavy metal in fish came from depositional heavy metal in algae of the fishpond. Plenty of heavy metal was accumulated in gill, liver, kidney of the fish, while the heavy metal contents in muscle were far less than the contents in other three organs of the fish. Detoxification was different between tropical species and Cyprinus carpio. In winter the detoxification of Cyprinus Carpio was less efficient than that of Tilapia nilotica and Colossoma brachypomum. The heavy metals were accumulated and transported to the muscle of Cyprinus carpio associating with the increasing pollution of the metals in the fish..更多还原
