Effect of Cynodon dactylon on the haematological parameters and haematocrit of grass carp Ctenopharyngodon idella (Val.)

The present study is aimed to investigate the effect of Cynodon dactylon on the haematological parameters of freshwater fish Ctenopharyngodon idella. The study reveals that there was a slight variation noticed in total serum protein, globulin, albumin, glucose, cholesterol and triglycerides. There was a significant variation observed in Red blood corpuscles (RBC), White blood corpuscles (WBC), Haemoglobin (Hb), MCH, MCHC, PCV in the blood of grass carp fed with control and Cynodon dactylon mixed diet. The protein content of experimental fishes showed higher value than other components. The result of the study indicates that the fish are rich source of animal protein and moderate amount of cholesterol and triglycerides. Hence, it suggested that the fish consumed medicinal plants are suitable for human consumption. Keywords: Grass carp, Cynodon dactylon, Haematology, Haematocrit
