对832尾黄鳝性腺周年变化的研究表明,黄鳝卵细胞在繁殖季节的发育不一致,属分批产卵类型,其产卵期为5~8月.黄鳝的个体绝对繁殖力与体长呈幂函数相关,回归方程为{N}(绝对繁应力)=0.3018{L(体长)}.其繁应力与成熟度呈显著正相关,但与肥满度关系不密切。
Studies on the annual changes of gonads of 832 Eel show that the development of egg cells of Eel is inconsistent in the breeding season and belongs to the batch type of spawning with the spawning period from May to August. The absolute fecundity of the eel was related to the body length as a power function. The regression equation was {N} (absolute stress) = 0.3018 {L (body length)}. There is a significant positive correlation between the stress and maturity, but it is not closely related to the fatness.
