Expression of CYP1A in the hepatopancreas of Merluccius merluccius, Trigla lucerna, and Liza ramada (pisces) in the wider vicinity of Bar harbor Montenegro

Abstract

The expression of CYP1A, a biomarker for the presence of xenobiotic compounds, was examined in three fish species from the wider vicinity of Bar harbor in winter and spring. Induction of CYP1A was observed in winter and increased further in spring. Several PCBs were found in seawater in winter. They decreased below the limit of detection in spring, when the PAH fluorene was detected. It is concluded that the constant presence of CYP1A expression is probably due to pollutants in the environment, whereas increased expression of CYP1A in spring results from exposure of the fish to fluorene. .
