Abstract

• In the present study, a total of 10782931 individuals, 40 species belonging to 30 genera, 17 families and eight orders from Pauk Inn (site I) and 780133 individuals, 33 species under 26 genera, 16 families and eight orders from Padonmilay Inn (site II) were recorded during October 2018 to September 2019. The total production fish weight was recorded over 283581 kg/yr from Site I and over 15802 kg/ yr. from site II. The water sample was collected from both study sites for analyzing some water parameters during planting and harvesting period of Melon spp. and other crops were examined by the laboratory of water supply and sanitation department of Mandalay. Some parameters of water temperature, pH and total alkalinity from both sites were fall within the EPA limit and the rest of the water parameters were unsuitable limit for fish fauna in the study area. This study was aimed to focus the limnology and sustainable utilization of floodplain for fisheries development.
