The effects of age and individual size on metal accumulation of Lagocephalus sceleratus (Gmelin, 1789) from Mersin Bay, Turkey

Abstract

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.

European eels and heavy metals from the Mar Menor lagoon (SE Spain)

“…The relationship between total length and trace element concentrations (existence or type of relationship) has been reported to vary according to tissue, trace element and species (e.g. Al-Yousuf et al, 2000;Ayas and Köşker, 2018;Canli and Atli, 2003;Szefer et al, 2003;Yeltekin and Oğuz, 2018;Yi and Zhang, 2012). However, specifically, the decrease in Pb concentrations in muscles with an increase in fish total length and/or weight has been identified in species such as Mola mola (Baptista et al, 2019) and Atherina hepsetus (Canli and Atli, 2003).…”

Determination of Heavy Metal Concentrations in Lessepsian Suez Puffer (Lagocephalus suezensis Clark and Gohar, 1953) from North-Eastern Mediterranean

“…Subsequently, this Lessepsian invasive species has established large populations along the coasts of many countries of the eastern basin such as Israel, Lebanon, Turkey (Mediterranean and Aegean coasts), Cyprus and Greece (Aegean and Ionian coasts), while still rapidly expanding westwards along the coasts of Egypt, Libya, and along the entire Tunisian coastlineq (Ben-Soussi et al, 2014). There is very limited information about puffer fish at the present time, including the systematic, zoogeography and growth in this area (Başusta et al, 2013;Kalogirou, 2013;Karunanidhi et al, 2017;Eken et al, 2017;Ayas & Köşker 2018;Manaşırlı et al, 2017).…”
