Abstract

Histological studies in organs like gill, liver and muscle of Lethrinus harak and Terapon jarbua were made to assess tissue damage due to concentration of heavy metals and organic compound on the polluted site (Al-Kumrah) compared with the unpolluted site (Al-Shoaibah). The histopathological investigations showed that heavy metals and organic compounds due to the discharge of sewage affected the vital organs and caused clear and marked damage in the gills, liver and muscles in fishes, collected from Al-Kumrah site, and considered as a biomarker to the low quality of water in this region compared with Al-Shoaibah area. Thus, a conclusion of the present study is that histopathological biomarkers can be valuable indicators of impaired health of fish and can reflect the effects of exposure to untreated and treated sewage. Therefore, the continue to discharge untreated sewage into Al-Kumrah site should be limited and water resources should be treated to eliminated the pollutants as well as improving the water quality for improving fisheries in this area to maintain human health.
