Abstract: Thirty-seven species in 10fish families were found in Shanmei Reservoir.They included 22species of Cyprinidae, accounting for 59.46% of the total, and 4species of Bagridae, accounting for 10.81% of the total.There were also respectively 2species of Channidae and Anguillidae, and one species of Cichlaidae, Siluridae, Serranidae, and Adrianichthyidae.Specifically, the growth characteristics of Aristichthys nobilis found in the reservoir were observed: (a) its body weight (W) could be related to the length (L) as W=0.0269×L2.9132; (b) its body length to the scale size (R) as L=0.0129×R+3.5323; (c) its Von Bertalanffy growth equations were Lt= 107.2167×1-e-0.1349 (t+0.1561) and Wt =22095.9566×1-e-0.1349 (t+0.1561) 3; (d) its growth inflection point occurred at 7.99-year-old; (e) its maximum body length, L∞, was 107.22cm; (f) its maximum body weight, W∞, reached 22.1kg;and, (g) the growth coefficients were k=0.1349and t0 =-0.1561.
