摘要

福壽螺於1979年自國外引入台灣後，因可食用部份有限，而遭養殖業者棄養而蔓延至全省各地，造成嚴重農業損失及生態環境衝擊。本文利用管柱及砂箱實驗來觀測福壽螺於水中活動趨勢與趨水性，並利用田區阻隔方式來探討其阻隔效率，並觀察福壽螺進入水田區之路徑。由試驗觀察得知福壽螺不適於長期生活於深水區，最喜生活於流速緩慢之田埂引水口及接近水面處，而且福壽螺之趨水性差，另利用田區周圍自然環境阻隔及避免以缺口方式作為進排水口可有效阻擋福壽螺進入田區。

The Pomacea canaliculata was introduced into Taiwan in 1979. Because the limitation of edible part that was abandoned raising by aquaculture leading to spreads to many regions in the inland. The situation caused serious agricultural losses and the ecological environment impact. This plan used the soil column and the sand-box experiments to observe the active tendency and the hydrotaxis of Pomacea canaliculata in water. In addition, this study used the block way in field to investigate the impediment efficiency of Pomacea canaliculata entering field and observed the pass way of their entering paddy field. The results showed that Pomacea canaliculata was not suitable living in the deep water with long time and their favorable seating place was living in the slow flowing zone, such as the water intake of a boundary ridge and the water surface. Moreover, the Pomacea canaliculata has poor hydrotaxis ability; therefore, using natural environment around the field to isolate them and in the entering and drainage port can not having gaps that should be effectively ways to prevent the Pomacea canaliculata entering the field area.
