Effects of Zinc Sulphateand Biochemical Profiles of the Fish Species rhohu (Labeo rohita), katla (Catla catla)

Water is contaminated by various industrial aspects, Here the present study determine the high concentration of the metal content of ZnS, which may alters the biochemical element in fishes. Indian major carps (IMCs) – rohu (Labeo rohita), katla (Catla catla) were used as suitable fish models invitro. Total protein, glycogen, cholesterol concentrations were examined in Gills, muscles and liver in both the test fishes. Specimens were also exposed for 96hr toxicity of varying concentration of 0.1, 0.5mg/l. The accumulation of total zinc suphide content when comparing the condition acute, chronic and in the recovery stages of both the fishes were significantly higher in Gills, muscle than liver .The results indicated that the biochemical parameters varied by the exposure of fish in high metal contamination.
