| Abstract: | The artificial propagation test was done under the different temperatures of 20℃, 23℃, 26 ℃, 29 ℃ and 32 ℃. The results showed that under the conditions of 26 ℃, the daily fecundity of Nothobranchius Guentheri was the largest, and the fertilization rate was the highest. 26℃ is the best temperature for Nothobranchius Guentheri reproduction. Ten mating patterns of broodstock were studied during the breeding, we found that when the mating patterns were 4 ♂ ＋ 1♀, 2 ♂ ＋ 1 ♀ and 1 ♂＋ 1 ♀ , the daily fecundity were higher, and the fertilization rate were also higher. 4 ♂ ＋ 1 ♀ , 2 ♂ ＋ 1 ♀ and 1 ♂ ＋ 1 ♀ were the best mating patterns for Nothobranchius Guentheri production; we also observed the spawning period of three batches of broodstock for 20 weeds under 25 ~26℃, it showed that duringl5 to 17 weeks, the daily fecundity of Nothobranchius Guentheri was the lar- gest, the daily fecundity was 20 to 30eggs/individual. |
