“…The changes in activity and content of antioxidants demonstrate a pollutant‐induced adaptive response in fish, and an attempt to neutralize the generated ROS (Kavitha and Rao, ). As reported, the levels or activities of antioxidants are potential biomarkers revealing a contaminant‐mediated biological effect on the organism (Cheung et al, ; Camus et al, ). Therefore, the change of the activities of GST, GR, GPx and the contents of GSH, GSSG (Fig.…”

Tilapia were exposed to sublethal concentrations of 0, 0.2, 2, 20, or 200 μg/L for 30 days, and then transferred to methomyl-free water for 18 days. GST, GPx, GR, GSH, and GSSG in tilapia serum were examined at 0, 6, 12, 18, 24, and 30 days after methomyl exposure and at 18 days after transferring to methomyl-free water. There were no significant changes in antioxidants activities and contents in serum of tilapia exposed to 0.2 μg/L. Significant increases in GST, GR, GPx, and GSSG accompanied by a decrease in GSH were observed following methomyl exposure to 2, 20, or 200 μg/L, suggesting the presence of oxidative stress. Thus, it would appear the 0.2 μg/L methomyl might be considered the no observed adverse effect level. Recovery data showed that the effects produced by lower concentration of 20 μg/L were reversible but not at the higher 200 μg/L concentration.

“…After 2 weeks of transplantation, LPO levels in both the gills and mantle of B. azoricus were in fact higher than in the two native populations, suggesting that a period of adaptation is necessary when a drastic change in the environmental conditions occurs (as occurred during recovery and subsequent redeployment). In a recent study, where total oxyradical scavenging capacity was evaluated in transplanted coastal mussels (Mytilus galloprovincialis) in the Venice lagoon, the authors underline that the translocation of animals can be a source of additional stress and that transplantation methods require good practice to minimize stress that can affect the balance between prooxidant and antioxidant forces in the mussels (Camus et al 2004). In a similar transplant study, the LPO products (MDA) were also elevated in M. galloprovincialis moved from a clean site to several polluted areas in the Venice Lagoon (Pampanin et al 2005).…”

Adaptation of the antioxidant defence system in hydrothermal‐vent mussels (Bathymodiolus azoricus) transplanted between two Mid‐Atlantic Ridge sites

ProblemAlthough hydrothermal vent environments are characterized by extremely high temperatures, low oxygen and are rich in potentially harmful chemical species, mainly hydrogen sulphide (H 2 S), methane (CH 4 ) and heavy metals (Mn, Fe, Cu, Zn, Ag and Cd), they are paradoxically home for some luxuriant animal communities AbstractThe vent mussel Bathymodiolus azoricus is the dominant member of the Northern Mid-Atlantic Ridge (MAR) hydrothermal megafauna, and lives in an environment characterized by temporal and spatial variations in the levels of heavy metals, methane and hydrogen sulphide, substances which are known to increase reactive oxygen species levels in the tissues of exposed organisms. To evaluate the effects of two contrasting hydrothermal environments on the antioxidant defence system of this vent mussel species, a 2-week transplant experiment was carried out involving mussels collected from the relatively deep (2300 m), and chemical rich, Rainbow vent field. These were transplanted to the shallower (1700 m), and relatively less toxic, Lucky Strike vent field. To achieve this objective, levels of superoxide dismutase, catalase (CAT), total glutathione peroxidase (GPx), selenium-dependent glutathione peroxidase and lipid peroxidation (LPO) were measured in the gills and mantle tissues of resident and transplant mussels before and after the transplant experiment. With the exception of CAT, the gills of the transplanted mussels had significantly higher antioxidant enzyme activity compared with the basal levels in the donor (Rainbow) and recipient (Lucky Strike) populations; whereas the antioxidant enzyme levels in the mantle tissues of the transplants reflected the baseline levels of activity in the native Lucky Strike mussels after 2 weeks. In contrast, LPO levels were significantly higher in both tissue types in the transplants than in either the source or the recipient populations, which suggested a response to hydrostatic pressure change (note, the transplant animals were brought to the surface for transportation between the two vent fields). The fact that the Rainbow mussels survived the transplant experience indicates that B. azoricus has a very robust constitution, which enables it to cope behaviourally, physiologically and genetically with the extreme conditions found in its naturally contaminated deep-sea environment.
