Abstract:
The influence of temperature and food on growth and survival rate of larvae leech of Whitmania pigra was studied in the laboratory. The resulst showed that there were significant variance on growth and survival rates of the young leech under different temperature conditions (P<0.05). The growth rate of the young leech was the fastest at 27 ℃, the survival rate was the highest at 27 ℃, the survival rate was the lowest at 33 ℃. The results also indicated that the growth rate and survival rate were significant difference by feeding different food (P<0.05). The growth and survival rate of the young leech were optimum by feeding Rotifer and Cipangopaludina, the survival rate was the lowest and the growth rate was the slowest by feeding yolk.
