The freshwater fish, Labeo rohita, treated with two different sublethal concentrations (1/10 and 1/3 of the 96 hr LC50) of arsenic, have revealed a significant decrease in the succinic dehydrogenase (SDH) activity in liver and muscle tissues throughout the period of 28 days of exposure. With the decline of SDH activity, the metabolic pathway has turned anaerobic to meet the increased energy demands during arsenic stress.

Abstract


The freshwater fish, Labeo rohita, treated with two different sublethal concentrations (1/10 and 1/3 of the 96 hr LC50) of arsenic, have revealed a significant decrease in the succinic dehydrogenase (SDH) activity in liver and muscle tissues throughout the period of 28 days of exposure. With the decline of SDH activity, the metabolic pathway has turned anaerobic to meet the increased energy demands during arsenic stress.
