Effect of Sodium Chloride on Hematological and Biochemical Profile in Common Carp (Cyprinus carpio L.)

This study was carried out to examine the effects of different concentrations of sodium chloride (0.1, 6, 9 and 12g/l) on hematological and biochemical picture of Common Carp (Cyprinus carpio) for 30 days. For this purpose, 80 fish at average weight of (125± 2 g) were randomly distributed into four treatments groups and exposed to four concentrations of sodium chloride treatments with two replicates /treatment (10 fish / replicate) and were fed with pelleted feed at 3% of their body weight twice daily. After 30 days of exposure hematological parameters (Hb, PCV, RBC, MCV, MCH and MCHC), glucose, lactate and total protein were also determined. Hematological and biochemical parameters showed significant increases (P≤ 0.05) with increases sodium chloride concentrations except MCV, MCH and MCHC .The results of this study indicated that hematological and biochemical parameters can be used to evaluate the responses of common carp to different levels of environmental salinity.
