Abstract
The present study aims to investigate the possible impact of aquatic pollution of Izmir Bay on resident fish. Gobius niger were sampled from two stations of the Izmir Bay, and gills and liver were examined histopathologically. The presence of pathological lesions in gills and liver of the fish as possible result of pollutant exposure was evaluated by semiquantitative analyses. The only histopathological changes found were hyperplasia, hypertrophy (12.5%, 18.8%), epithelial degeneration (18.8%, 25%) in gill and fatty livers (12.5%, 25%) of the fishes from both study sites, respectively. The moderate manifestation of pathological lesions in organs of Gobius niger from the presumably Bostanh site may be either the result of substantial protective and detoxification capabilities of this fish species, or from recent measures to reduce water pollution in Izmir Bay such as the installment of wastewater treatment plants.
