摘要
对114尾沙塘鳢进行了测定,全长范围为8.4～19.9cm,体重范围为8.8g～134.2g,其体长和体重呈指数函数增长关系,相关关系式为:W=0.0327L2.9513。绝对怀卵量在822～5430粒之间,相对怀卵量为66～219粒/g。成熟系数5.89～35.56。
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=0.0327L^29513 （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.
