Última Ecological studies on fish farms of el-fayoum depression (egypt) OceanDocs Konsowa, A.H.. This study was carried out at the fish farms of El-Fayioum province during 2003 farming season. They extend along the eastern bank of Lake Qarun. These farms derive its water and drainage wastes into Diar El-Berka Drain. pH values at the chosen farms ranged between 7.43 and 8.91 and its values are certainly optimum for fish culture. Salinity levels at fish farms adjacent to Lake Qarun (Goda 2, 9.5‰) are generally much higher than the other fishing ponds due to seepage from the lake water. The major nutrient concentrations (N & P) at the main feeder were much higher than the corresponding values at fish farms. Nitrogen concentrations that represented by NO2-N, NO3-N and NH4-N indicated the dominance of NH4-N over NO2-N and NO3-N at the selected fish...
