Investigation on biochemical responses of the Silver Carp (Hypophthalmicthys molitrix) under acute exposure to copper nitare

In order to investigation of acute toxicity heavy metal copper on blood biochemichal parameters of silver carp (Hypophthalmicthys molitrix), a total of 135 fish (with mean weight 52.6 ±8.1 gr and mean length 17.2 ± 2 cm) were exposed to 0, 5 and 10 mg/L of Cu (NO)2. Results of biochemical parameters showed significant changes, but not about cholesterole. Glucose levels were increased significantly (P<0.05) in 24 than 12 hours. Total protein levels were decreased significantly (P<0.05) at treatment 5 mg/L at both times. Albumon levels were decreased significantly (P<0.05) in 12 hours. Based on results, biochemichal parameters are useful to monitoring of copper acute toxicity in Sliver Carp.
