Abstract:
|
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.
Key words: Herbivorous, macrophyte, Pomacea canaliculata, utilization coefficient, , ,
