According to the literature review, this is one of the pioneer works in the observation of hemocytes in the cylopoid copepods. The homogenization and centrifugation methods were used to isolate the hemolymph of the zooplanktons. Using eosin stain, hemocytes were stained and identified under a trinocular light microscope. The presence and absence of cytoplasmic granules in the hemocyte cells were used to classify the hemocytes identified. Granulocytes, semi-granulocytes, and hyalionocytes were identified as three forms hemocytes. In a Neubauer counting apparatus, total and differential counts of hemocytes were performed. The results were recorded as 80,000 cells per µl of hemolymph and 45% hyalinocytes, 39% Granulocytes and 16% semi granulocytes.
