摘要
对蒙古油[歺又鱼]（Hemiculter bleekeri warpachowskyi）的繁殖季节、繁殖习性、繁殖力、性比等繁殖生物学指标进行了研究。结果表明：蒙古油[歺又鱼]属敞水性产卵类型,粘性卵,为一次产卵类型。蒙古油[歺又鱼]初次性成熟年龄为1龄,繁殖季节为6月中旬至7月下旬,以7月中旬为产卵盛期。蒙古油[歺又鱼]个体绝对生殖力F为2021～15470粒,个体体长相对生殖力FL为230～1137粒/cm,个体体重相对生殖力FW为273～700粒/g;个体体长相对生殖力、个体体重相对生殖力分别和体长、体重成二次方程和三次方程关系。繁殖前期雌雄性比1∶0.83,繁殖期雌雄性比为1∶1.11。
The reproductive season, habitat, fecundity and sexual ratio of H. bleekeri warpachowskyi have been studied. The results show that H. bleekeri warpachowskyi is an open water spawner that does not spawn by batches and eggs spawed is emplastic. It is reaching the first sexual maturity in the second year. The reproductive season starts from late June to July and the flourishing season is early July. Individual absolute fecundity is 2021 ～ 15470 cells, the body length and weight relative fecundity is 230 ～ 1137 cells/cm and 273 ～ 700 cells/g respectively. The sexual ratio between the female and male is 1 ： 0.83 and 1 ： 1.11 before and in reproductive season respectively.
