Abstract :

The aim of this study was to determine the significant seasonal variations in the number of leucocytes in the blood of Ctenopharyngodon idella. Differential Leucocyte Count of a fish indicate the immunological and physiological healthy state. In the present study the DLC of grass carp in Lymphocyte shows that values were higher in post eeding season in the sexes. These values were again to the lower side in eeding season. Monocyte in the grass carp indicates that the mean values were in higher side in pre–eeding period and post –eeding period,the lower values were noted in the eeding period. Neutrophil of this carp indicates that the mean values were higher in the eeding season lowering in the post –eeding season and moderate in the pre–eeding season. Eosinophile studies also indicates that the mean values were higher in the eeding period gradually declining in the post – eeding period as well as in pre– eeding period. In the study of basophil it was found that mean values were higher in eeding period as 1.2 � 0.07% in male fish. In the post–eeding period the values were recorded as 0.9 � 0.02% and in the per– eeding period the values recorded as 0.9 � 0.085% . Total count of leucocytes, differ from species to species. It is also related to sex; age, sexual difference, environment and season. The leucocytes counts were affected by endogenous and exogenous factors such as eeding periods, water quality etc. The leucocytes value rice continuous by up to certain immune power, length, weight range, after which there occur a gradual fall.
