摘要:

【Objective】The present experiment was conducted to study the effect of temperature on growth, development, reproduction and feeding behaviour of Pomacea canaliculata in order to find out a suitable temperature for its population reproduction, and specially to investigate its growth and development mechanism to deal with disastrous conditions caused by it. 【Method】The survival and growth rate, egg production and food intake of P. canaliculata were investigated by raising them under various temperature conditions at different developmental stages. 【Result】The young and adult P. canaliculata attained highest survival rate (over 90%) at 15-20℃, the body weight increment rate of young P. canaliculata, egg production quantity and rate of egg hatching reached the highest at 30℃. The average maximum food intake level of young and adult P. canaliculata was found highest at 30 and 35℃, respectively. The threshold temperature for development of eggs was 14.19℃, and the effective accumulated temperature was 137.41℃·d. 【Conclusion】The results revealed that 30℃ was the best temperature for the growth, development and reproduction of P. canaliculata.
