Copper-induced oxidative stress and biomarkers in the postlarvae of Penaeus indicus.

The objective of the present research is to study the levels of reactive oxygen species (ROS) and protein carbonyl (PC) and the functional protein levels of metallothioneins (MT) in Penaeus indicus postlarvae (PL) upon sublethal copper exposure and to determine the biomarkers. The PL were exposed to sublethal copper of 0.164 ppm.

Response of glutathione system and carotenoids to sublethal copper in the postlarvae of Penaeus indicus.

The objective of this study is to determine the effect of sublethal copper on the glutathione system and carotenoids of Penaeus indicus postlarvae (PL) when subjected to short- and long-term exposure in the laboratory. The PL were exposed to 0.1641ppm (sublethal) copper for a period of 30 days with sampling intervals of 24, 48, 96h and 10, 20, 30 days.
