Preliminary comparative study was conducted on autumn propagation per- formances of Paramisgumus dabryanus and Misgurnus anguillicaudatus. The count- able and measurable properties, fatness, mature coefficient, relative fecundity, as well 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 Paramisgumus dabryanus (P〉0.05), while significant difference existed between male and female Misgurnus anguillicauda- tus (0.01〈P〈0.05); the mature coefficients of Paramisgurnus dabryanus and Misgurnus anguillicaudatus were of 6.56% and 11.36%, respectively; the relative fecundities of Paramisgurnus dabryanus and Misgurnus anguillicaudatus were of 115.70 eggs/g and 147.69 eggs/g, respectively; the fertilized rates of Paramisgurnus dabryanus and Mis- gurnus anguillicaudatus were of 90.62% and 97.52%, respectively; and the hatching rates of Paramisgumus dabryanus and Misgurnus anguillicaudatus were of 92.45% and 97.16%, respectively. It was concluded that Misgumus anguillicaudatus was bet- ter than Paramisgurnus dabryanus in breeding performance in autumn. 展开更多
