摘要
为了解黄颡鱼繁殖的生物学特性,对繁殖期雌、雄鱼形态学特性,雌鱼的怀卵量、繁殖力等进行了测定。结果表明:锦江河黄颡鱼在繁殖期的个体绝对怀卵量与体重、体长均呈直线相关,平均绝对繁殖力为2 757粒/尾,平均相对繁殖力为74.38粒/g。
Characteristics of Pelteobagrus fiulvidraco during reproductive period were determined, including morphologic characteristics,individual fecundity and fertility. The results show that the individual absolute fecundity is linearly and directly correlative to body length and body weight,the average individual absolute fecundity is 2 757 eggs, and the average individual relative fecundity is 74. 38 egg/g.
