Golden Apple Snail(GAS) (Pomacea canaliculata), popularly known in the Philippines as “golden kuhol” is considered a serious invader in a paddy ecosystem. Rice farmers consider it as a notorious invasive species and a serious pest in several rice farms. In this study, we model the predation of rice plants and weeds by GAS. We formulate three ordinary differential equations to model the simplified dynamics of apple snails, rice plants and weeds in the presence of harvesting on snails. We then investigate the mathematical features of the model and analyze the stability of equilibria. Actual death and harvesting rates on GAS gathered from actual field experiments conducted on the enclosed rice paddies are used for the parameters in the numerical simulations to demonstrate the potential effect of snail harvesting.
