Keywords: Groundwater, carp fish culture, southern Iraq


Common carp fish Cyprinus carpio were cultured in areas dependent on groundwater and other surface water with a weight rate of 10 grams in five basins, one of which is controlled and the others are groundwater. The fish growth was compared with a basin filled with surface water in al-Mutaiha area in southern Iraq. The chemical elements and environmental factors of water in ponds, including chloride, magnesium, calcium, potassium, sodium, sulfate, carbonate, salinity and pH, were measured. The growth parameters were calculated as the increase in weight and the qualitative and relative growth of cultured fish. The highest increase in weight of groundwater was 144 g, surface 164 g and specific growth (4.1% day) for surface water (3.1% day) for groundwater. It was found that there were no significant differences (P> 0.05) between fish growth (weight increase and qualitative and relative growth) cultured on groundwater and other cultivated on surface water.
