Abstract

The ecological status, fish resource potential and the socio-economic value of Selameko and Gomit reservoirs, south Gondar zone were studied between, 2014-2015, through identifying the physico-chemical characteristics, composition and abundance of plankton and fishery potential and socio-economic value of the reservoirs. Though spatial variations were not statistically significant, seasonal variation of NO2, Alkalinity, TDS, salinity and K25 were significant in Gomit. While seasonally, pH, DO and NO2 were statistically significant in Selameko reservoir. A total of 42 and 53 phytoplankton species belonging to seven taxonomic groups and 21 and 23 zooplankton species belongs to three taxonomic groups were identified from Selameko and Gomit reservoirs, respectively.
