长湖沙塘鳢个体繁殖力的研究

Individual Fertility of Odontobutis obscurus in Changhu Lake

研究了长湖沙塘鳢(Odontobutisobscurus)体重、卵巢重和繁殖力的关系。结果显示,卵巢重、绝对繁殖力和相对繁殖力与体重间关系显著,随着体重的增加,卵巢重呈直线增加,绝对繁殖力呈对数曲线增加,相对繁殖力呈对数曲线减小。单位体重的卵巢重与体重关系不显著。

The body weight, ovary weight and fertility of Odontobutis obscurus were determined and analyzed. The results showed that ovary weight, absolute and relative fertility are related to body weight significantly. With increasing body weight, ovary weight increases in a linear style, and absolute fertility increases in curve line and relative fertility decreases in curve line. Ovary weight per body is not related to body weight significantly.
