Abstract：The influences of greenhouse and large-size, middle-size, and small-size on propagation performance of red swamp crayfish Procambarus clarkii were investigated using the method of control and comparative test for eight months. The results showed that the mean water temperature of was more 3.44 ℃ in the plastic greenhouse than outdoor during the coldest season in winter every year (from late December to mid-January), and the temperature was above 5 ℃ in the pond water in the greenhouse. The difference was not significant in the average culture density of the postlarvae between inside and outside the plastic greenhouse (P＞0.05), the crayfish size was 1.46 times in inside than that in outside the plastic greenhouse. The middle-size broodstock was significantly larger than the small broodstock (P<0.01). The average culture density of postlarvae was significantly higher in middle-size broodstock than that in large-size broodstock (P<0.01). Small size crayfish had significantly increase in the recovery rate of parents after spawning. By observation, in January in the winter, the seedling rate of crayfish with eggs reached 80%. This findings indicate that the greenhouse facilities increase in the water temperature in winter, promoting the growth of crayfish seedlings, improving the size of crayfish. With the suitable broodstock body weight of 25—35 g, the findings can provide reference for selection of broodstock and early propagation of red swamp crayfish.
