山美水库的鱼类资源调查结果表明:山美水库所有鱼类组成包括10科37种,其中鲤科22种,占59.46%;鮠科4种,占10.8%;鳢科和鳗鲡科各2种;鳅科、丽鱼科、鮨科、鲶科、青鳉科、银鱼科等各1种。鳙鱼的生长特性调查表明:鳙体重与体长的关系为W=0.0269×L2.9132,体长与鳞径关系为L=0.0129×R+3.5323,Von Bertalanffy生长方程为Lt=107.2167×[1-e-0.1349(t+0.1561)]及Wt=22095.9566×[1-e-0.1349(t+0.1561)]3。生长拐点出现在7.99龄,生长系数k=0.1349,t0=-0.1561。山美水库鳙的渐进体长可达107.22cm,渐进体重可达22.1kg。
The results of the survey of fish resources in the Shamei Reservoir show that all the fish species in Shamei Reservoir include 37 species in 10 families, of which 22 species are Cyprinidae, accounting for 59.46% of the total; Cyprinidae is 4 species, accounting for 10.8% of the total; Species; Turtle Branch, Cichlidae, Trichosanthes, catfish Branch, Green Barracuda Branch, Silverfish, etc. 1 species. The results showed that the relationship between body weight and body length was W = 0.0269 × L2.9132, the relationship between body length and scale diameter was L = 0.0129 × R + 3.5323, and the growth equation of Von Bertalanffy was Lt = 107.2167 × [1 -e-0.1349 (t + 0.1561)] and Wt = 22095.9566 × [1-e-0.1349 (t + 0.1561)] 3. The inflection point of growth appears at 7.99 years old, the growth coefficient k = 0.1349, t0 = -0.1561. Mountain US reservoir 渐 gradual body length up to 107.22cm, progressive body weight up to 22.1kg.
