The present study was carried out for a period of 90 days (02 February to 02 May, 2017) with a view to investigate comparative haematological changes in Cyprinus carpio communis in relation to pre spawning and post spawning phases. Experimental breeding in common carp was performed for this haematological study. The haematological parameters such as Total Erythrocyte Count (TEC), Total Leucocytes Count (TLC), Haemoglobin (Hb), Packed Cell Volume (PCV), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH) and Mean Corpuscular Haemoglobin Concentration (MCHC) of the experimental fish were compared in relation to sex and their reproductive status. The results clearly indicated that the blood parameter levels such as TEC, MCV, MCH and MCHC (P <0.05) were highly significant and statistically significant Hb (P <0.05) was observed during pre-spawning period in both the sexes while differences in TLC and PCV (P >0.05) were statistically non-significant between males and females. During the post spawning period the TEC, PCV, MCV, MCH and MCHC (P <0.05) were statistically highly significant whereas differences in TLC and Hb, (P >0.05) were statistically non-significant in both the sexes.
