Abstract

In the last few decades pollution of the aquatic ecosystems is a serious problem. Persian Gulf due to special condition of it is one of the ecosystems affected by contaminants. The present study aimed to investigate the effect of industrial and municipal wastewater in gill and of Liza klunzingeri. In order to do this study, 45 fish were collected from three sampling sites in Bandar Abbass: delta of Shure River (control), ship building and suru in Aban 1390. After anesthesia of fishes, specimens from of second arch in right gills were fixed in formalin 10%. Routine procedure histology methods were done and five micron thick sections were obtained and stained with hematoxilin-eosin then examined in light microscopy. Histopathological alterations were not seen in control gill. Histopathological alterations in gills of two polluted stations were including: epithelial lifting, oedematus space, hyperplasia of epithelial cells, lamellar fusion, clubbing, blood congestion and hyperplasia of chloride and mucous cells. Meanwhile parasite pollution was seen in some specimens of suru station also aneurism was seen in a few specimens of ship building station, too.
