Biochemical alterations in fish fingerlings (Cyprinus carpio) exposed to sublethal concentration of linear alkyl benzene sulphonate

Abstract

Fish fingerlings (Cyprinus carpio) were exposed to sublethal concentrations of linear alkyl benzene sulphonate (0.005 ppm) for 24, 48, and 96 h under static laboratory conditions. Alterations were noted in the levels of glycogen, lactic acid, sialic acid, and acid and alkaline phosphatases in the gill, liver, and kidney. This chemical may impair metabolic processes in fingerling carp, because increased exposure resulted in significant increases in lactic acid and decreases in glycogen and sialic acid along with inhibition of acid and alkaline phosphatase activity.
