  Morphometric and meristic features, metal accumulation and chemical composition of Sarotherodon melanotheron and its intestinal parasites were investigated in August, 2013. The Standard length of Sarotherodon melanotheron range between 13.10-21.50 cm with Mean ± SD of 16.15 ± 1.97, (p<0.001) and Head length range from 1.50-2.70 with Mean ± SD of 2.15 ± 0.28, (p<0.001). Heavy metal concentrations were determined in water, sediment, intestinal parasites, gills and liver of Sarotherodon melanotheron were analysed using Atomic Absorption Spectrophotometry to determine concentration of Pb and Zn. Metals in the water, sediment and parasites were above WHO level. The concentration of Lead and Zinc were higher in the sediment (Pb-18.82 and Zn-21.52) than the water (Pb-2.66 and Zn-15.41). The liver accumulated highest con.. Read More»
