Abstract

The present work had been carried out in order to determine the freshwater gastropods in the three rivers of Esperanza, Agusan del Sur, Philippines namely Ojot River, Wawa River and Sabang-ojot River. Collection of gastropods was done from September 30-Ocober 3, 2015 through opportunistic method along 100-m transect line established in accessible area. Physico-chemical parameters of water were obtained using multi-parameter tester. Results of physico-chemical parameters suggest that three sites have freshwater characteristics. Five species of freshwater gastropods were collected and identified in the three sampling sites. Sabang-ojot River has the highest number of freshwater gastropods species recorded because of its muddy to clayish substrate and rich vegetation. L. caperata and P. canaliculata were the ubiquitous species. Assessment of freshwater gastropods in a longer period of time is highly recommended.
