Abstract

In the last decades, the decline of coastal waters resources has forced fisheries to expand into deeper waters. However, while the increase of industrial activities make it essential to find biological models that can explain pollutants dynamics, little is still known about pollutants distribution, dynamics, and their possible effects on deep-water organisms. In this context, new information on the concentrations of trace metals (Arsenic, As; Cadmium, Cd; Copper, Cu; Mercury, Hg; Lead, Pb) in muscle, liver and gonads of blackmouth catshark, Galeus melastomus, from north-western
Mediterranean (northern Tyrrhenian Sea) are presented. Significant differences between males and females were found in the concentrations of three of the five trace elements in gonads. Lower concentrations of trace metals were found in the ovaries, and this could be due to the almost continuous vitellogenic activity which could transfer contaminants to developing oocytes.
