Abstract
[Objective] The aim was to study the life-history pattern of Pseudohemiculter dispar. [Method] Taking the ecological parameters of 15 speices of fishes whose life-history patterns were known as references, seven ecological parameters of asymptotic body-length (L∞) , asymptotic body-weight(W∝), growth coefficient(k) , natural mortality (M) , primary reproductive age(Tm) , maximum age ( Tmax ) and population fecundity(PF)were selected to judge the life-history pattern of P. dispar by using principle component analysis, cluster analysis and Beverton-Holt dynamic comprehensive model. [Result] In the lst-2nd principal components plot and lst-3rd principal components plot of 16 fish species , P. dispar was clustered into the same group with r-selected fish. In the results of cluster analysis, K-selected fish were clustered into one branch, and P. dispar and the known r-selecled fish furmed another branch. Beverton-Holt dynamic comprehensive model also showed that P. dispar showed a typical yield curve of r-selected fish. [Conclusion] P. dispar was identified as a kind of r-sele,cted fish.关键词
