Abstract

Aims Histopathological study is one of the most appropriate ways to evaluate the effects of contaminants in aquatic organisms. The aim of the present study was to evaluate the histopathological changes and histopathological alternation index (HAI) in Liver tissue of Pomadasys kaakan and Lutjanus johnii in the Oman Sea. Materials & Methods In this study, 18 number Pomadasys kaakan and Lutjanus johnii were captured from 3 stations including Ramin, Konarak, and Haft-Tir by gillnet in winter 2016. In order to study the type and severity of tissue lesions, fixation stages in Bowen’ s solution, tissue processing in tissue processing device, paraffin impression, tissue sections 4-5 microns thickness with microtome, stained with hematoxylin and eosin were done for Liver tissue of both fish species. Findings Tissue lesions observed in fish Livers included hepatocyte vacuolization, enlargement of sinusoid, adipose cell accumulation, blood congestion, nuclear pyknosis, hemorrhage, and necrosis. In addition, these tissue lesions were higher in Haft-Tir station and lower in Ramin station than in other stations. In Haft-Tir station, histopathological alternation index in Liver tissue of both fish species were higher than other two stations. Conclusion Due to the high traffic of the Haft-Tir dock and its close proximity to other docks in the area, the accumulation of pollutants at this station is high and lead to more severe tissue lesions in fish.
