| Abstract: | Life history parameters of 55 fish species were gathered from litterature and this study,which include maximum weight, age, body weight and size at first-maturity, relative productivity and diameter of mature eggs, etc. Principal component analysis was used to analyze the ecological measures in 55 fish species. Based on the multiple values,r-K continuum in 55 fish species was drawn out.Correlation coefficient between age and body size at first maturity was the largest among ecological parameters. Life history patterns of fishes in Sichuan were mostly that of rselection. only those of sturgen and paddlefish were not competible with life patterns of other species. |
