“…Should these antioxidant responses be overwhelmed by ROS, lipid peroxidation (LPO) and membrane damage will occur (Nakano et al, 1999). Indeed, the induction of these antioxidant responses and LPO have been commonly employed as biomarkers of oxidative stress (Di Giulio, 1991;Livingstone, 1993;Lackner, 1998;Ahmad et al, 2000) both under field and laboratory conditions.…”

Chattonella marina, a red tide or harmful algal bloom species, has caused mass fish kills and serious economic loss worldwide, and yet its toxic actions remain highly controversial. Previous studies have shown that this species is able to produce reactive oxygen species (ROS), and therefore postulated that ROS are the causative agents of fish kills. The present study investigates antioxidant responses and lipid peroxidation in gills and erythrocytes of fish (Rhabdosarga sarba) upon exposure to C. marina, compared with responses exposed to equivalent and higher levels of ROS exposure.Even though C. marina can produce a high level of ROS, gills and erythrocytes of sea bream exposed to C. marina for 1 to 6 h showed neither significant induction of antioxidant enzymes nor lipid peroxidation. Antioxidant responses and oxidative damage did not occur as fish mortality began to occur, yet could be induced upon exposure to artificially supplied ROS levels an order of magnitude higher. The result of this study implies that ROS produced by C. marina is not the principal cause of fish kills.

“…Glutathione conjugation with these reactive molecules neutralizes their electrophilic site and makes them more soluble. While superoxide dismutase may be best known antioxidant enzymes (Lackner, 1998;Cossu et al, 1997). In addition, a high superoxide dimutase activity level is induced following exposure of fish to the mixture of heavy metals only.…”

This study was carried out to investigate the potential effects of sublethal concentration (5 mg.L -1 ) of combined heavy metals (1.25 mg.L -1 of each) including cadmium (Cd), copper (Cu), lead (Pb) and zinc (Zn) on Nile tilapia, Oreochromis niloticus after exposure for 1, 3, 5 and 7 days in order to evaluate the protective role of vitamin E and combination of selenium (Se) with vitamins A, C and E against the toxicity of these heavy metals. Exposure of O. niloticusto heavy metals only for 1, 3, 5 and 7 days resulted a significant increase in the values of antioxidant enzymes (GSH, CAT, GST, GR and GPx) in liver and gills of O. niloticus. While the exposure to the mixture of heavy metals and vitamin E or heavy metals with selenium protected the liver and gill of O. niloticus. The activities of antioxidant substances and free radicals (SOD, GSH, GSSG, TAC and MDA) formation were also determined after 1, 3, 5 and 7 days of exposure to heavy metals only or heavy metals with vitamin E or selenium. Antioxidants (both enzymatic and nonenzymatic) can provide protection against deleterious metal-mediated free radical attacks. Vitamin E and combination of selenium (Se) with vitamins A, C and E prevent the majority of metal-mediated (Cd, Cu, Pb, and Zn) damage. Therefore, this study confirms on the powerful protective potential of the antioxidants vitamin E alone and a combination of selenium with vitamins A, C and E against the toxicity of Cd, Cu, Pb and Zn on O. niloticus.

“…Oakes et al (2004) have also demonstrated the increase of TBARS levels in the gonads of white suckers exposed to pulp and paper mill effluents as well as municipal sewage treatment plant effluents. Oxidative stress originated from detergent, pesticides, organophosphorus compounds, several metals and other environmental pollutants may induce free radicals and cause lipid peroxidation (Lackner, 1998;Nunes et al, 2006). One of the important features of these enzymes is their inducibility under oxidative stress.…”
