摘要
食蚊鱼(Gambusia affinis)是苏州河一期治理后于2001年7月河里出现的第一种鱼。2010年7～8月在苏州河流域设置五个采样点,对食蚊鱼样品进行种群特征的数据统计和分析,检测鱼体、胚胎和样点水质的重金属离子含量。结果表明,目前河水重金属离子没有对食蚊鱼的生存造成影响,同时发现,苏州河食蚊鱼个体普遍偏小,种群正在形成发展中,合适的水文环境也是关系到食蚊鱼能否生存繁衍的一个重要因素。
The Gambusia affinis was the kind of first fish discovered in the Suzhou in July 2001. Based on collection of the Gamubusia at five sample localities in a part of River after the first of governance drainage area along the fiver, The population charactr/stics including sex ratio, body length and weight and reproduction ability were measured and analyzed and heavy metals in river water and fish body were anlyzed. The results showed that the heave metals in the river water did not affect to the Gambusia growth. The bodies of Gambusia in the fiver were smaller than that of the normal fish and the population of the Gambusia was developing. A suitable hydrology environments was vary important for development of the Gambusia population in the Suzhou River.
