摘要：Golden apple snail was a harmful invasive gastropod in Asian wetlands. In order to clarify the effect of Pomacea canaliculata on macrophytes in paddy fields, feeding preference and nutrients utilization of snail were studied. Feeding preference of snail was Alternanthera philoxenoides > Monochoria vaginalis > Oryza sativa L. Snail showed a higher approximate digestion coefficient on Oryza sativa L. than that on Monochoria vaginalis . Nitrogen utilization coefficient of snail on Alternanthera philoxenoides was significantly higher than that on Oryza sativa L. Snail exhibited a higher calcium utilization coefficient on Alternanthera philoxenoides and Monochoria vaginalis than that on Oryza sativa L. Oryza sativa L. was not preferred among three plants under the same available and exposure condition.
