Blood serum concentration of protein, albumin and globulin in locally available four fresh water fishes

In the normal functioning of physiology of fish, the albumin and globulin along with protein in the blood plasma js needed as albumin is required for transportation of organic substances and globulin for immunity. Their presence provides normal physiology and health condition of the fish. Hence, in the present investigation blood serum protein, albumin and globulin concentration was studied in some locally available four fresh water carp fish species to understand the differences and their significance in health condition of the fishes in an aquatic body. The fishes selected for this study are four fresh water fishes which includes three major carps such as: Labeo rohita, Cirrhana mrigala, Catla catla and Pangasius bocourti. All these fishes were collected live from local market brought by the fisherman in living condition. The blood was collected from the fishes sacrificed at the spot through hypodermic 5ml syringe and transferred to the tubes separately labelling as per fish species and brought for the determination of serum protein, albumin and globulin by applying specific methods in a laboratory. The results indicated that the serum protein concentration ranged from 4.6g/dl to 7.8g/dl, the serum albumin from 1.0g/dl to 1.9g/dl and serum globulin from 3.3g/dl to 6.6g/dl in four fish species studied. The serum protein concentration in the serum was found to be higher with less concentration of albumin and increased level of globulin as compared to albumin. The significance of these serum levels suggests that the fishes are provided with proper transportation mechanism of nutrients for growth and health condition in an aquatic body.
