| Abstract: | Based on the samples of Ovalipes punctatus collected from fisheries resource survey in the Zhoushan fishing ground from 2006 to 2007, we reported the biological characteristics of O. punctatus, analyzed their seasonal variations, and compared our results with previous studies. The carapace length of O. punctatus varied from 9 to 75mm, with an average value of 43.8mm; the carapace width varied from 10 to 98mm, with an average value of 54.9mm. The body weight ranged from 0.4 to 167.4g, with an average value of 40.4g. The male individuals were larger than females. Significant seasonal variations of carapace width were observed in both female and male O. punctatus. Small individuals dominated the O. punctatus population in spring; in summer, the composition proportions of carapace width were similar for female and male; and larger male individuals significantly increased in winter. The female and male ratio was about 1:1.03, which was greatly different with previous reports. The feeding intensities were mainly at level 1, occupying about 41.3%; and the average feeding intensity level was 1.87. Compared with previous research results, the O. punctatus became smaller, but grew faster. The results also indicated that the non-finishing practice in summer and the subsequent continuous fishing could affect individual growth and resource dynamics. |
