“…The feed used in intensive and semi-intensive fish farmers contains both Cd (about 440 ng/g) and Pb (about 650 ng/g). These values, however, are similar to those found in other feed pellets commonly used in aquaculture (McKee et al 2008). Pb level in the different tissues demonstrates that in these fish foodborne Pb is poorly absorbed, as previously described for other fish species used in aquaculture (Ciardullo et al 2008).…”

The distribution and potential bioaccumulation of dietary and waterborne cadmium and lead in tissues of sea bream (Sparus aurata), a major aquaculture species, was studied in relation to three different fish farming systems. Metallothionein levels in fish tissues were also evaluated. Results demonstrate that metal concentrations in various tissues significantly vary among fish culture systems. Different tissues show different capacity for accumulating heavy metals. The content of both cadmium and lead is not strictly correlated with that of metallothionein. Indeed, the marked accumulation of both metals in liver, as well as the high lead content found in gills and kidney, are not accompanied by a concomitant accumulation of metallothioneins in these tissues. No correlation is present between heavy metals and metallothionein content in muscle tissue. The results also demonstrate that cadmium accumulates mainly via dietary food, whereas lead accumulation is not of food origin. Noteworthy is that the concentration of the two metals found in muscle in all instances is lower than the limits established by European Union legislation for fish destined for human consumption.

“…A similar correlation was observed in the fat of fish meat from producers 3, 4, and 5, who used the same feed, which differed from the feed used by producers 1, 2, and 6. Other studies also confirmed the influence of the type of the feed on the content of tested compounds (10).…”

The aim of the study was to determine the content of chlorinated hydrocarbon residues in fat of different assortment of rainbow trout (Oncorhynchus mykiss). The research material consisted of 108 fish from six different producers. Thirty-six fish were analysed as fresh, 36 fish as frozen after six months storage, and 36 fish as traditionally smoked. Chromatographic determination of γ-HCH, DDT, DDD, and DDE was performed with an Agilent Technologies 6890N. The presence of the compounds was detected in all tested fat samples. The content of γ-HCH was five-fold higher in frozen fish (average 2.11 ng/g of fat) than in fresh and smoked fish (0.42 ng/g of fat and 0.43 ng/g of fat, respectively). Total DDT (ΣDDT) content was found higher after refrigerated storage but did not exceed acceptable levels, indicating that the fat in the meat of rainbow trout is an attractive nutritional compound with a low concentration of tested chemical pollutants.

“…Fish meal and fish oil make up around 50-70% of all ingredients in fish feed. Previous studies (e.g., Easton et al 2002;Antunes and Gil, 2004;Hites et al 2004;Navas et al 2005;Bordajandi et al 2006;Maule et al 2007;Kelly et al 2007;McKee et al 2008;Serrano et al 2008;Shaw et al 2008;Botaro et al 2011;Grigorakis &Rigos, 2011) found amounts of DDT, PCBs, and PBDEs in Atlantic salmon diets of 36.66, 10.9, and 36.66 ng g-1, respectively, in their Mediterranean mariculture investigation. These undesired contaminants in farmed high energy Atlantic salmon were caused by fish oils from contaminated pelagic fish species used as a feed element in salmonid diets (Berntssen et al 2016).…”

Increased agrochemical based agricultural activities along the Volta Basin and aquacultural practices from the cage farms have raised concerns about the potential ecological risk to the aquatic ecosystem. To assess this, caged tilapia samples were analysed for polychlorinated biphenyls (PCBs) and organochlorine pesticide (OCP).Fish samples in acetone/hexane (2:1v/v) solvent medium were sonicated on ultrasonic bath, shaken electronically, cleaned by solid-phase extraction and analysed by GC/ECD for OCPs and GC/MS for PCBs.The levels of OCPs reported in the fish ranged; ND – 2.310 µg/kg (fish farm A), <LOD – 4.260 µg/kg (fish farm B), <LOD – 6.109 µg/kg (fish farm C) and ND – 0.878µg/kg (control). The highest concentration of 6.109 µg/kg was encountered for δ-HCH in the muscles of Tilapia from fish farm C, whiles p,p'-DDE recorded the lowest in farm A. The levels of the OCPs detected in the cage tilapia were below the MRL proposed by the EU. Six PCBs congeners; PCB 18, PCB 28, PCB 52, PCB 101, PCB153 and PCB 180 were detected in the cage tilapia. The concentrations of the indicator congeners ranged from 0.288 ng/g to 0.931 ng/g dw, 0.042 ng/g to 1.321 ng/g dw, 0.260 ng/g to 10.657 ng/g, and ND-0.298ng/g dw in fish farm A, B, C and control respectively. The highest mean concentrations of PCB 153 (8.524 ± 1.5960ng/g) was found in farm Estimation of the EDIs and HQs for the pesticides do not present potential health risk to the consumers of the cage tilapia fish from the studied farms.
