A kind of Pomacea canaliculata prevention and treatment device, installation one dyke of what enter water position, include a framework and an at least baffling device. Above-mentioned casing structure is at the frame with an end facing water and a backwater end, and a free air space is formed inside what said frame, and above-mentioned end facing water is configured to an inclined-plane, and above-mentioned inclined-plane is equipped with an at least channel and flows into above-mentioned free air space by above-mentioned framework outside for the water flow of above-mentioned dyke, the channel position of the above-mentioned baffling device setting above-mentioned framework of what, and it is configured to a filter element for passing through for above-mentioned water flow and Pomacea canaliculata being stopped to enter above-mentioned free air space. This creation Pomacea canaliculata prevention and treatment device can effectively obstruct Pomacea canaliculata and Pomacea canaliculata ovum enters farmland, and can prevent sundries cap product and influence flow rate of water flow on prevention and treatment device, separately can be applicable to the dyke of various different aperture modes, practicability is substantially improved.一種福壽螺防治裝置，安裝於一堤防的入水位置，包含有一框體以及至少一阻隔裝置。上述框體構造成具有一迎水端及一背水端的框架，並於上述框架內部形成一流通空間，而上述迎水端構造成一斜面，且上述斜面設有至少一通道供上述堤防的水流由上述框體外部流入上述流通空間，上述阻隔裝置設置於上述框體的通道位置，並構造成一供上述水流通過並阻擋福壽螺進入上述流通空間的過濾元件。本創作福壽螺防治裝置能夠有效阻隔福壽螺以及福壽螺卵進入農地，並可杜絕雜物卡積在防治裝置上而影響水流流速，另可應用在各種不同開孔方式的堤防，大幅提升實用性。
