| Abstract: | 114 of O. obscurus were measured. The results showed that the individual total length ranged from 8.4cm to 19.9cm , the individual weight ranged from 8.4g to 134.2g . The relationship between body length (L) and body weigh(W) could be described by the formula: W=0.0327L2.9513(R2=0.9603). Absolute egg-holding number was between 822 and 5 430 eggs per fish,and relative egg-holding number was between 66 and 219 eggs per gram fish body weight. The maturity coefficient was between 5.89 and 35.56. |
