摘要
通过对江苏水产养殖鱼类的外来物种进行实地调查和资料信息采集,共统计整理出51个外来鱼种,总结了这些物种原产地、食性、耐受温度、生态类型等基本信息,并从繁殖特点、生活习性和入侵历史等方面选择评价指标,对部分外来鱼种的入侵风险做出初步评估,提出了防治外来鱼类入侵的若干建议。
In this paper, the exotic cultured fish species in Jiangsu province were investigated. There were 51 exotic fish species, and their basic information such as the origin, feed, tolerant temperature, ecotype and so on was summed up. Their invasive risk was primarily evaluated by several evaluation indexes chosen from the characters of reproduction, behavior and invasive history. Suggestions on the prevention and control of exotic fish invasion were put forward.
