对大鳞副泥鳅和青鳅秋季繁殖性能进行初步的比较研究。测定了可数可量性状、肥满度、成熟系数、相对怀卵量、受精率和孵化率，得出了生长方程。结果表明，肥满度在两种鳅之间差异不显著（P>0.05），但发现大鳞副泥鳅雌雄差异不显著（P>0.05），而青鳅雌雄差异显著（0.01<P<0.05）；性成熟系数分别为：大鳞副泥鳅6.56%、青鳅11.36%；相对怀卵量分别为：115.70粒/g、147.69粒/g；受精率分别为：90.62%和97.52%；而孵化率为92.45%和97.16%；结果显示：在秋季繁殖季节，青鳅在繁殖性能方面比大鳞副泥鳅要好。

Preliminary comparative study was conducted on autumn propagation per-formances of Paramisgurnus dabryanus and Misgurnus anguil icaudatus. The count-able and measurable properties, fatness, mature coefficient, relative fecundity, as wel as the fertilized and the hatching rates were measured. The results showed that there was no significant difference between the fatness of the two species (P>0.05) and between the fatness of male and female Paramisgurnus dabryanus (P>0.05), while significant difference existed between male and female Misgurnus anguil icauda-tus (0.01<P<0.05); the mature coefficients of Paramisgurnus dabryanus and Misgurnus anguil icaudatus were of 6.56% and 11.36%, respectively; the relative fecundities of Paramisgurnus dabryanus and Misgurnus anguil icaudatus were of 115.70 eggs/g and 147.69 eggs/g, respectively; the fertilized rates of Paramisgurnus dabryanus and Mis-gurnus anguil icaudatus were of 90.62% and 97.52%, respectively; and the hatching rates of Paramisgurnus dabryanus and Misgurnus anguil icaudatus were of 92.45%and 97.16%, respectively. It was concluded that Misgurnus anguil icaudatus was bet-ter than Paramisgurnus dabryanus in breeding performance in autumn.
