“…part 3.3.). Some studies have reported a negative effect of contaminated sites on the K condition index: contamination negatively affected the condition index of geophagus, Geophagus brasiliensis (Linde-Arias et al 2008) and stickleback (Roussel et al 2007;Sanchez et al 2008a). However, effects of contaminants depend on fish species, as Bennett and Janz (2007) reported different impacts of metal contamination on K for burbot, Lota lota, and Northern pike, Esox lucius.…”

Human activities have led to increased levels of various pollutants including metals in aquatic ecosystems. Increase of metallic concentrations in aquatic environments represents a potential risk to exposed organisms, including fish. The aim of this study was to characterize the environmental risk to fish health linked to a polymetallic contamination from former uranium mines in France. This contamination is characterized by metals naturally present in the areas (manganese and iron), uranium, and metals (aluminum and barium) added to precipitate uranium and its decay products. Effects from mine releases in two contaminated ponds (Pontabrier for Haute-Vienne Department and Saint-Pierre for Cantal Department) were compared to those assessed at four other ponds outside the influence of mine tailings (two reference ponds/department). In this way, 360 adult three-spined sticklebacks (Gasterosteus aculeatus) were caged for 28 days in these six ponds before biomarker analyses (immune system, antioxidant system, biometry, histology, DNA integrity, etc.). Ponds receiving uranium mine tailings presented higher concentrations of uranium, manganese and aluminum, especially for the Haute-Vienne Department. This uranium contamination could explain the higher bioaccumulation of this metal in fish caged in Pontabrier and Saint-Pierre Ponds. In the same way, many fish biomarkers (antioxidant and immune systems, acetylcholinesterase activity and biometric parameters) were impacted by this environmental exposure to mine tailings. This study shows the interest of caging and the use of a multi-biomarker approach in the study of a complex metallic contamination.

“…The condition factor, which assumes that heavier fi sh of a given length are in better condition, is able to indicate fi sh fi tness under stress of pollution as metabolic trade-off is required to deal with detoxification and the energy available for growth may thus be reduced (Fang et al, 2009). Some reports have demonstrated that the CF declines in fi sh exposed to environmental pollutants (Khan, 2003;Roussel et al, 2007). In this study, a signifi cant lower CF was observed in the CBZ-treated group with the highest concentration (E3 group) (Fig.…”

“…Also, ratios of organ weight to body weight have been used in various stress-related studies. The most frequently used of these is the hepatosomatic index (HSI) (Roussel et al, 2007). Several studies have demonstrated that CF and HSI are potential indicators of toxicant eff ects, providing information on the ability of an individual to tolerate chemical pollution or other kind of environmental stress (van der Oost et al, 2003;Kopecka and Pempkowiak, 2008).…”

Recently, residual pharmaceuticals are generally recognized as relevant sources of aquatic environmental pollutants. However, the toxicological effects of these contaminants have not been adequately researched. In this study, the chronic toxic effects of carbamazepine (CBZ), an anticonvulsant pharmaceutical commonly present in surface and ground water, on physiological condition status and muscle-based biomarkers of rainbow trout were investigated. Fish were exposed at sublethal concentrations of CBZ (1.0 microg l(-1), 0.2 mg l(-1) and 2.0 mg l(-1)) for 42 days. Compared with the control, there was a significant lower (P < 0.05) condition factor in fish exposed at the highest concentration of CBZ (2.0 mg l(-1)), but the hepatosomatic indices in all groups were not significant changes. At lower CBZ concentration (1.0 microg l(-1), 0.2 mg l(-1)), the antioxidant enzyme activities were induced slightly, except catalase, while at the highest concentration (2.0 mg l(-1)) oxidative stress was apparent as reflected by the significant higher lipid peroxidation and protein carbonyls in the fish muscle, associated with a significant inhibition of antioxidant enzymes activities. Moreover, energy metabolic parameters (RNA-DNA ratio, Na(+)-K(+)-ATPase) were significantly inhibited in muscle of the fish exposed at the highest concentration (2.0 mg l(-1)), compared with the control. In short, CBZ-induced physiological and biochemical responses in fish were reflected in parameters measured in this study, which suggest that these biomarkers could be used as potential indicators for monitoring residual pharmaceuticals present in aquatic environment.
