| 摘 要： | 2006-2008年对西江珍稀鱼类自然保护区江段进行鱼类组成与生境调查,共采集鱼类81种,隶属于11且25科69属.其中洄游鱼类8种,外来种6种,土著淡水鱼类67种.以种类数及其多样性指数分析,表明西江保护区鱼类种类多样性较高.优势种是鲮鱼、赤眼鳟、广东鲂,主要经济鱼类为广东鲂、赤眼鳟、鲮鱼、黄尾鲴、花鰶,珍稀濒危物种有花鳗鲡.珠江长臀鮠、台细鳊及多种珠江水系特有鱼类.保护区鱼类生态类型多样,以定居性、杂食性和底栖鱼类为主.保护区江段水文动力条件独特,河床底质结构复杂,是西江鱼类栖息、产卵的理想场所,栖息地破坏、过度捕捞等是保护区鱼类生物多样性的主要胁迫因素.

| Abstract: | Survey aiming at the wild fish resources in Provincial Rare Fishes Natural Reserve of Xijiang River in Zhaoqing City. 81 fish species belonging to 11 orders, 25 families and 69 genera from 2006 to 2008, among them there are 8 river-sea migratory species, 6 exotic species and 67 native freshwater species. Analysis of the species numbers and diversity indices showed that fish diversity of the Reserve was high. Cirrhina moitorella, Squaliobarbus curriculus and Megalobrama hoffmanni were the preponderant specie... |
