摘要:The morphological study of haemocytes from the freshwater crab Paratelphusa hydrodromous was carried out by light microscopy. Total haemocytes count and differential count of crab haemocytes were made. Total count of haemocytes was noted as 140+3.288 cells/mm3. Three types of haemocytes were identified in fresh water crab Paratelphusa hydrodromous: hyalinocytes, semigranulocytes and granulocytes. The proportion of hyalinocytes was found to be 35%, whereas semigranulocytes were found as 62% and granulocytes 43%.
