摘　　要： 通过设置12个采样点,对固始县主要河流及水库鱼类资源开展调查,收集鱼标本48种,隶属于7目12科38属。其中鲤形目无论是在属的数量及物种的种类均为最多,分别占总种数的69.00%和66.00%,其次是鲈形目和鲇形目。按鱼类栖息环境划分,静水定居型和溪流定居型为主要类型。按水层垂直分布划分,中上层鱼类最多,占总种类数的41.67%。按食性类型划分,其中杂食性鱼类最多,占总种数的50.00%。本次调查的固始县鱼类可划分为4个区系,中国平原区系复合体29种,占总种类数的60.42%。对比以往资料发现固始县鱼类多样性及种群分布和数量上均呈现衰退趋势,应从多方面加强保护。 We collected the fish in Gushi County from 12 sampling sites which covered the main rivers and reservoirs. We collected 48 species of fish, which belonged to 7 orders, 12 families, 38 genera. Cypriniformes was the biggest group both from the number of genera and the species, accounting for 69% and 66% respectively. It followed by the Perciformes and Siluriformes. According to the differences of the habitat environment, hydrostatic settlement and ravine settlement were the main ones. According to the water-course vertical distribution, pelagic fishes were the maximum which hold 41.67% in all species. According to the differences of feeding habits, omnivore fish is the maximum, account for 50.00%. There were four fish faunas in Gushi county according to our survey, China Plain fish Fauna Complex have 29 species, accounted for 60.42%. Compared with the former fish record of Gushi county, the fish diversity, population size and distribution have declined in these decades. So we should take more measures to protect the limited fish resources.
