To determine the best spawning temperature and weight of Whitmania pigra and the hatching temperature of its eggs.
Observe the state of W. pigra spawning and hatching were observed under different temperatures and weights conditions.
25 degrees C is the most appropriate temperature for W. pigra spawning and incubation, the best spawning weight of W. pigra was around 20 g. The temperature influenced the lost weight after spawning significantly and was proportion to the lost weight. The body weight showed no substantial influence to the lost weight after spawning. The egg weight of W. pigra which body weight was below 2.0 g was proportion to the hatching rate. The same relationship was not observed in W. pigra over 2.0 g.
确定宽体金线蛭的最佳产卵温度和体重及其卵的孵化温度。
观察宽体金线蛭在不同温度和体重条件下的产卵和孵化状态。
25℃是宽体金线蛭产卵和孵化的最适宜温度，宽体金线蛭的最佳产卵体重约为20克。温度对产卵后的失重有显著影响，且与失重成正比。体重对产卵后的失重没有实质性影响。体重低于2.0克的宽体金线蛭的卵重与孵化率成正比。体重超过2.0克的宽体金线蛭未观察到相同关系。
