摘　　要：研究了真泥鳅(Misgurnus anguillicaudatus)和大鳞副泥鳅(Paramisgurnus dabryanus)体长与怀卵量的关系。结果表明,两种泥鳅的平均绝对怀卵量都随体长的增加有明显的增加趋势,体长在10 cm以下时,两种泥鳅的平均绝对怀卵量没有显著差异;体长在10～25 cm时两种泥鳅的平均绝对怀卵量均存在显著差异;同一体长段真泥鳅的怀卵量高于大鳞副泥鳅。The relationship between the body length and fecundity in Paromisgumus dabryanus and Misgurnus anguillicaudatu was studied. The results showed that the average absolute fecundity increased as the body length increasing in both loaches. There are no significant difference of the average absolute fecundity with the body length less than 10 cm; and significant difference of average absolute fecundity was found in both loaches with body length of 10-25 cm. In addition, the fecundity of M. anguillicaudatu was more than P. dabryanus with the same body length.
