Abstract: The main objective of this study is to measure the blood cell dimension of the cultured fish Cyprinus carpio, Ctenopharyngodan idella and Hypophthalmichthys molitrix. Basic knowledge from this study is important for hematological research, cytological studies and clinical diagnosis. Since study of blood cells in many different species of fishes provides an interesting comparison of cell size in relation to their activities and habits an attempt was made to study morphometric data of blood cells in Cyprinus carpio, Ctenopharyngodan idella and Hypophthalmichthys molitrix. The fish were collected from the cultured pond in west Godavari region of Andhra Pradesh. For the morphometrical analysis of blood cells, blood was drawn from the caudal vein and blood smears were prepared immediately after blood was obtained and stained with Giemsa stain. The cell size of Erythrocytes, Erythroblasts, Thrombocytes, Monocytes, Large lymphocytes, Small lymphocytes, Neutrophils, Eosinophils and Basophils were measured irrespective of the sex. Thrombocytes are the most abundant blood cells after erythrocytes and are recognized easily from lymphocytes by morphological features and size The size of blood cells (Range & Mean of long axis and short axis) was measured in micron meter (μm) for the three exotic carps. These types of studies on different blood cells size in different species can give us information about cell size in order to their habit and habitat and provides a numerical objectification of the most suitable modifications that can help in research applications.
