“…A high Hg concentrations in muscle tissue of fish could thus represent a concern for human health. As a consequence, Hg concentrations have been extensively surveyed in Mullus surmuletus and M. barbatus throughout the Mediterranean Sea (Capelli et al 2004;Conti et al, 2012;Copat et al, 2012;Corsi et al, 2002;Falcó et al, 2006;Harmelin-Vivien et al, 2009;Kucuksezgin et al, 2001;Martínez-Gómez et al, 2012). But as previously observed by Dierking et al (2009), most of the studies on contamination in fish were carried out over a single area, where contamination was expected to be high.…”

Mercury (Hg) is one of the main chemicals currently altering Mediterranean ecosystems. Red mullet (Mullus barbatus and M. surmuletus) have been widely used as quantitative bio-indicators of chemical contamination. In this study, we reassess the ability of these species to be used as efficient bio-indicators of Hg contamination by monitoring during 18 months Hg concentrations in muscle tissue of mullet sampled from 5 French Mediterranean coastal areas. Mean concentrations ranged between 0.23 and 0.78 μg g(-1) dry mass for both species. Values were consistent with expected contamination patterns of all sites except Corsica. Results confirmed that red mullets are efficient bio-indicators of Hg contamination. Nevertheless, the observed variability in Hg concentrations calls for caution regarding the period and the sample size. Attention should be paid to environmental and biologic specificities of each studied site, as they can alter the bioaccumulation of Hg, and lead to inferences about environmental Hg concentrations.

“…The species is a territorial benthic fish with well-known ecological and physiological characteristics and pronounced sensitivity to different kinds of pollutants. Red mullet tends to accumulate pollutants to a greater extent than other species (Zorita et al, 2008) and has therefore been used as a bioindicator for pollution monitoring of polychlorinated biphenyls (PCBs), PAHs, alkylphenols and metals (Insausti et al, 2009;Harmelin-Vivien et al, 2009;Ausili et al, 2008;MartinSkilton et al, 2006b). While pollutant-induced enzymes such as 7-ethoxyresorufin-O-deethylase (EROD), benzo(a)pyrene monooxygenase (B(a)PMO), GST and UDPGT have been widely studied in this species (Regoli et al, 2002;Corsi et al, 2002;Porte et al, 2002;Burgeot et al, 1994), no data is currently available, to our knowledge, on the modulation of toxicologically relevant genes at the transcription level.…”

Aim of this study was to evaluate the responsiveness of red mullet (Mullus barbatus) liver detoxification enzymes to PAHs at transcriptional and post-transcriptional levels in the field. Fish were captured in the north-eastern Adriatic Sea, close to an oil refinery. Sixteen PAHs (EPA) were determined in sediments and fish fillets; transcription levels of cyp1a, cyp3a and abcc2 genes and EROD, BROD, B(a)PMO, BFCOD, GST and UDPGT enzymatic activities were measured. Levels of PAHs in sediments reflect the oil pollution gradient of the area, with weak correspondence in fish fillets. cyp1a gene transcription and EROD, B(a)PMO and BFCOD activities were significantly induced in the oil refinery site, and a slight up-regulation of cyp3a and abcc2 was also observed. GST and UDPGT remained unchanged. The present study provides the first data on detoxification responses at transcriptional levels in the liver of red mullet and confirms phase I enzymes as suitable biomarkers of exposure to PAHs in field studies.

“…Fish accumulate heavy metals as they are in the upper levels of the food chain. Therefore, fish especially demersal fishes are used as indicators of ecosystem contamination in the monitoring programs for the determination of metal pollution in seas (Has-Schon et al 2008;Harmelin-Vivien et al 2009;Özden et al 2010;Alkan et al 2012). Red mullet and whiting are generally known as demersal fish species.…”

This study aims to determine heavy metal accumulation levels in the muscles tissues of two economically most important demersal fish species in the Eastern Black Sea, Turkey, red mullet (Mullus barbatus) and whiting (Merlangius merlangus), and evaluate the effects of fish species, sampling locations, fishing season and size groups on heavy metal accumulation levels. Chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd) and lead (Pb) concentrations in fish muscle samples were measured with Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Co, Zn, As and Cd accumulation levels in both species differed significantly (P<0.05). The metal concentrations of muscle tissues of both species, in general, were higher during summer and autumn. In the study, the differences in concentrations levels of As and Pb in whiting, Co, Cu, and Pb in red mullet muscle tissues were significantly related to fishing locations. The results of metal concentrations were compared with various legal limits such as Turkish Food Codex (TFC 2011), European Communities Commission Regulation (EC 2006) and Food and Agriculture Organization (FAO 1983) and the obtained metal levels of fish muscle tissues of both species were found to be below the limit values which are a threat to human health.
