Data Collection The coordinates of the two sampling sites, Don Chaing Ban and Don Sawan, were recorded using GPS and validated with the geo-referencing method to display the collecting localities on the map. Figure 2 presents the general overview of the two sampling sites. Gill nets, measuring about 2,000 meters in length and 2 meters in depth in different mesh sizes, were used for collecting freshwater fish from March to April 2011. Results and Discussion At least 23 species of freshwater fish were collected and identified (Table 1), where species richness had higher records in the littoral zone than the limnetic zone. Seven species of freshwater fish were gathered at every collection period, namely: Puntius brevis, Hampala dispar, Oxyeleotis marmoratus, Tetraodon leiurus, Henicorhynchus siamensis, Osteochilus hasselti and Notopterus notopterus. Four species were identified as both rare and indigenous (Mystus nemurus, Trichogaster trichopterus, Channa striata and Macrognathus siamensis) (Table 1). Figure 2.
