- Abstract
- Samplings have been monthly collected in Tongyeong and Sacheon of Gyeongsangnam-do, using traps. A total of 748 individuals were sampled from February 2007 to January 2008. We analyzed monthly changes in maturity stages and sex ratio. Mean biomass (total wet weight) of the female specimens ranged from 129.8 to 3,381.4 g and that of the male specimens ranged from 128.6 and 2,378.4 g. The spawning periods were May to June and September. The fecundity ranged from 5,715 eggs at 252.0 g to 240,990 eggs at 3,381.4 g of total wet weight. The relationship between total wet weight (TW) and fecundity (F) was F = 26.539 TW1.1548 (r2 = 0.8199) and fecundity increased with total wet weight. Sex ratio was not significantly different from the 1:1 (p > 0.05).
