Abstract

lake-shore-lady-zucchini-noodles-shrimp-scampi-2_d2f166122222dc1eacfc6132c1b665fe.today-inline-largeIncreasing amount of industrial and commercial chemical discharge into the aquatic environment has led to pathological side effects on aquatic organism. Water soluble fraction (WSF) of crude oil can pollute water and cause histopathological alterations in fish. Therefore, sea water pollution with crude oil could detrimentally impact the fish health. The aim of the present study was to assess the effect of different concentrations of WSF on muscle of yellow fin sea bream. The fish were exposed to 0% (control), 2%, 4%, 8% and 16% of WSF for a period of 21 days. The histopathological alterations were examined in four categories of circulatory, degenerative, proliferative and inflammatory. Inflammatory changes in control group was lower than that in 8% and 16% WSF exposed groups (p<0.01), and in 2 % and 4% WSF exposed groups was lower than that in 8% and 16% WSF exposed groups (p<0.01). In conclusion, the present study showed the effect of concentration and period of exposure to WSF on yellow fin sea bream. Iran is one of oldest Middle East producers of crude oil, so monitoring adverse histopathological effect of pollution could help keep yellow fin sea bream from waterborne pollution and prepare the ground for further studies.
