Oil pollution of waters, in addition to disrupting the physiological function of fish, leads to irreparable damage to human health during transmission through the food chain. Therefore, the possibility of accumulation of petroleum hydrocarbons in the edible tissues of fish is of particular importance. In this study, samples of yellowfin seabream (Acanthopagrus latus; Houttuyn, 1782) were collected from the Khowr-e Musa area in the Persian Gulf using bait traps. after twenty days of adaptation to the laboratory conditions (South of Iran Aquaculture Research Center), the fishes was divided into five groups with two replications in tanks containing 300 liters of seawater. The groups were then exposed to concentrations of 0, 2, 4, 8 and 16% water associated fraction (WSF).
The results of the study of the amount of total petroleum hydrocarbons in the gills and kidney tissue showed a significant increase on days 10 and 20 of the experiment, which increased slightly with increasing WSF concentration (P <0.05). While liver and muscle tissue, considering exposure time and WSF concentration, no significant difference was observed (P> 0.05). The results of the present study showed the possibility of accumulation of TPH in the gill and kidneys of yellowfin seabream, under the influence of concentration and duration of exposure to WSF. Therefore, considering the high economic value of the Sparidae family, it seems necessary to provide appropriate management methods to control oil pollution in the Persian Gulf.
