The golden apple snail-Pomacea canaliculata was an alien species and introduced into Korea as table use in 1983. This species is possible pest in direct seeded rice paddy in Korea. We investigated the effects of this exotic snail on the macrophytes and the water quality in water canal. Also, the basic life cycle of this species and the overwintering ecology in Chungnam and Jeonbuk province were elucidated. A survey of natural water canal in Korea showed that high densities of the snail were associated with absences of macrophytes-Hydrilla verticillata, Ceratophyllum demersum, Spirodela polyrhiza and Lemna perpusilla. Experiments in water tank also demonstrated that the golden apple snail can cause the loss of macrophytes, and increase the EC(Electric conductivity), COD(Chemical oxygen demand), T-N(Total nitrogen) and T-P(Total phosphorus) in water. |
