摘要
2015年8-9月,我们对信阳市潢川县鱼类资源开展调查。针对潢川县主要河流、水库水系分布特点,共设置8个采样点,以潢川县境内淮河、潢河、白露河、紫泥河和水库为调查重点,并结合当地农贸市场收集鱼类样本。本次调查共收集鱼标本41种,隶属于5目11科36属。其中鲤形目种类最多,占总种数的73.17%,其次是鲈形目和鲇形目,各占总种数的12.19%和9.76%,鲱形目和合鳃鱼目各1种,各占总种数的2.44%。调查结果显示:潢川县鱼类物种较丰富,群落较复杂,鱼类在摄食、繁殖及栖息习性等方面呈现多样化特征。根据鱼类区系复合体学说,潢川县鱼类资源主要以江河平原区系复合体和南方平原鱼类区系复合体种类为主。
