In this study, heavy metal levels in muscle and liver tissues of different age groups of Lagocephalus sceleratus caught in the Mersin Bay were investigated. Six different age groups were determined among fishes caught using commercial trawlers from the Mersin Bay. The lengths of fish were measured between 17 cm and 68 cm, the weights were measured between 265 g and 3955 g. Cadmium (Cd), Lead (Pb), Chromium (Cr) and Arsenic (As) levels were investigated using ICP-MS. The heavy metal concentrations in the liver and muscle tissues in L. sceleratus were found to be As>Cr>Cd>Pb and As>Cr>Pb>Cd, respectively. It was observed that with the increased ages of pufferfish, the levels of heavy metals determined in both muscle and liver tissues were increased.
