摘要
2016年10-11月,对南阳市淅川县鱼类资源开展调查,共收集鱼标本57种,隶属于7目14科45属。其中鲤形目种类最多,占总种数的68.42%;其次是鲈形目和鲇形目,分别占总种数的14.04%和8.77%;鲑形目2种,占总数的3.51%;鳉形目、颌针鱼目和合鳃目各1种,各占总种数的1.75%。淅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,淅川县鱼类资源主要以江河平原区系复合体和南方平原区系复合体为主。
An investigation on fish resources in Xichuan County of Nanyang was carried out from October to November in 2016. Fifty-seven species were collected, belonging to 45 genus, 14 families and 7 orders. Cyprini- formes was the dominant species in this area, which accounted for 68.42% of the total, Perciformes and Siluri- formes accounted for 14.04% and 8.77% respectively.
