Marine pollution is one of the main concerns of countries surrounding the Persian Gulf, which receives a great deal of contaminations. In this study, the histological alterations of kidney in Achanthopagrus latus collected from Musa creek were used to evaluate the effects of pollution on the aquatic organisms. In the present study, 50 A. latus were collected from five sampling stations in Musa creek including 1. Petrochemical, 2. Jaafari, 3. Majidieh, 4. Ghazaleh, and 5. Zangi. The kidneys of the fishes were separated and fixed in Bouin‘s solution for 12 h. The samples were then studied based on the routine histological methods. The histopathological changes in the kidneys of A. latus included glomerular dilatation, reduction of urinary space, melanomacrophages aggregations, occlusion of tubular lumen, tubular degeneration and necrosis. Histopathological Alteration Index (HAI) was determined based on the frequency of pathological changes in kidney of the fishes. The highest level of HAI for kidney of A. latus was observed at the Petrochemical station. The lowest level of HAI was related to Zangi station. The results of present study showed that the histopathological alternations of kidney in Achantopagrus latus are caused by the Musa creek contamination and there is close relation between the amount of these alterations and the environmental pollution.
