The aim of this study was to evaluate the toxicity effect of Cadmium heavy metal on some serological parameters of Silver carp which have been in the vicinity of cadmium for a short term. In this study a total of 135 fish with mean weight of 50±10grand mean length of 13±1cm were placed in 9 aquariums of 90-liter capacity, in contact with 0.5 and 10 mg/L of CdCl2.Sampling of fishwas done randomly every 12 hours until 96 hours from caudal vein. The results showed that, the level of triglyceride in 24 and 48 hours decreased significantly, but showed no significant increase in 72 hours. The level of cholesterol increased significantly at 72 and 96 hours with increasing the concentration of cadmium (P<0/05). Glucose level increased significantly in 72 hours, but significantly decreased with increasing the concentration of cadmium in 72 and 96 hours (P<0/05). The level of total protein decreased significantly in 24 and 96 hours with increasing the concentration of cadmium, and in 72 hours increased significantly (P<0/05). The level of albumin increased significantly in 96 hours. Based on these results, biochemical parameters are useful for monitoring of cadmium acute toxicity in Silver Carp.

The aim of this study was to evaluate the toxicity effect of zinc heavy metal on some serological parameters on Silver carp in the vicinity with zinc in short term. In order to do this study a total of 135 fish with mean weight 50±10gr and mean length 13& More
The aim of this study was to evaluate the toxicity effect of zinc heavy metal on some serological parameters on Silver carp in the vicinity with zinc in short term. In order to do this study a total of 135 fish with mean weight 50±10gr and mean length 13±1cm were located to adjacent to 0.5 and 10 mg/L of Zn (NO3)2 in 9 Aquarium with 90 liter of capacity.Sampling of fish was done randomly each 12 hours until 96 hours from caudal vein. The result showed that the level of cholesterol in 10 mg/L treatments in 96 hours were significant difference with 5 mg/ L and control treatments (p<0/05).
The results showed that the minimum amount of cholesterol in 10 mg/L treatment in 96 hours was (10.83±0.2 mg/ dL) and the maximum amount was found in 5 ppm treatment in 48 hours was (102.7±22.7 mg/dL). Mean triglyceride fluctuated, so that the maximum amount of triglyceride was found in 10 mg/L treatment in 12 hours (93±14) mg/dL) and the minimum in 96 hours in 5 mg/L treatment was (24.4±2 mg dl). By increasing the concentration of zinc. albumin level were increased significantly. The minimum amount was found in control treatment which was (0.73±0.14 g/dL) and the maximum level in 5 m/g/L treatment at 96 hours was (9.03±0.6 g/dL). Total protein levels were decreased significantly (p<0.05). The minimum amount of total proteins in 5 mg/L treatment at 96 hours was (0/043±0/003) g/dL, and the maximum amount was at 12 hours in 10 mg/L treatment at (3/53±0/3)g/dL. Based on results, Hematological and biochemical parameters are useful for monitoring of Zinc acute toxicity in Silver carp.

The aim of this study was to evaluate the toxicity effect of lead heavy metal on some serological parameters on Silver Carp in the vicinity with lead for a short term. In order to do this study a total of 135 fish with mean weight of 50±10 gand mean length of 13& More
The aim of this study was to evaluate the toxicity effect of lead heavy metal on some serological parameters on Silver Carp in the vicinity with lead for a short term. In order to do this study a total of 135 fish with mean weight of 50±10 gand mean length of 13±1 cm were placed in adjacent to 0, 5 and 10 mg/l of Pb (NO3 )2 in 9 aquariums of 90 liter capacity.Sampling was done randomly each 12 hours for 96 hours from caudal vein of the fishes. The results showed that there was a significant difference in the amount of hemoglobin in 24 hours, between the control and treatments. The level of glucose was increased significantly by increasing the concentration of lead and passing of the time. The levels of triglyceride and albumin did not change significantly (P>0/05). The level of cholesterol increased significantly until 72 hours and after that decreased significantly. Amount of total protein increased significantly by increasing the concentration of lead and time. Based on the results, biochemical parameters are useful for monitoring of lead acute toxicity in Silver Carp.
