摘要
山东内陆水域分属黄（河）、淮（河）、海（河）三大水系,通过多年调查,现知山东淡水鱼类有115种和亚种,分别隶属于12目20科73属,其中鲤科有69种和亚种,占总种数60％。无野鲮亚科和裂腹鱼亚科鱼类,鲃亚科仅有1种。鲤科中以江河平原区类群为主的特点十分突出,在淡水鱼类区划中属江河平原区的一部分。山东位于黄河下游属河海亚区,其鲤科鱼类与长江下游的江苏省（属江淮亚区）很相似,与辽河（属辽河亚区）鱼类比较,组成也较接近,可见亚区的划分主要是依据各区域鲤科外的属种组成,说明鲤科鱼类在江河平原区中组成的特殊性和分布的广泛性。
Shandong inland waters belong to three main river systems, i. e. Yellow River, Huai River and Mai River. As known at present on the basis of previous and present surveus 115 species and subspecies occur in Shandong and they belong to 73 genera, 20 families and 12 orders. Among them, 69 species and subspecies belong to the Family Cyprinidae or accounting for 60% of the total. Among the total 12 subfamilies of Cyprinidae, 10 subfamilies occur in, and the subfamilies Labeoninae and Schizothoracinae are absent in Shandong. Among the 10 subfamilies, 9 subfamilies are the East Asia elements and 1 subfamilies (with only 1 relict species) is the South Asia elements. The fish fauna of Shandong belongs to the East China (Plain) Region. Shandong is located in lower reaches of Yellow River (belonging to Wwangho-Haiho Subregion). The fishes of Cyprinidae are similar with that of Jiangsu which is located in the lower reaches of Yangtze River (belonging to Kiang Huai Subregion). Compared to that of Liao River (belonging to Liao River Subregion), excepts for a few cold water fishes, the fishes of Cyprinidae are also similar. The subregions are divided according to the elements of genera and species except for the Cyprinidae fishes.
