Golden apple snail (GAS) Pomacea canaliculata (Lamarck), an invasive species, was first introduced in southern and eastern Asia around 1980. It came from Argentina and Taiwan, meant for local consumption and for export as a gourmet item. In its introduced range, it became the top pest of aquatic crops such as rice and taro. Reducing GAS densities during the off-season (nonrice-growing months) should significantly reduce crop damage during rice planting months, but the lack of information on off-season GAS survival hinders the development of an effective management strategy. Hence, we estimated the percent survival of various GAS sizes for 3 mo after storage in nylon net bags (680 cm long × 450 cm wide) at the PhilRice screenhouse.
