Abstract:
The present study deals with the impact of bulk Zinc oxide on biochemical and
hematological characteristics of Rohu Labeo rohita. Bulk zinc oxide was preliminary
characterized by using SEM, EDAX, FT-IR and XRD. The physico-chemical characteristics of
water sample were analyzed before the experiment. Median lethal toxicity (LC50) test of bulk zinc
oxide are 0, 3, 6, 12 and 24mg/L on Labeo rohita was conducted for the period of 96hrs. Based on
the median lethal test, sub-lethal test on Labeo rohita were conducted with 1/100th, 1/50th and
1/10th LC50 value of bulk ZnO for T1,T2 and T3 respectively for 14 days and behavior of the fish
was recorded. After 14 days hematological parameters such as RBC, WBC, Hb, Hct, neutrophil,
lymphocytes and platelets and biochemical parameters
