abstract
Laboratory experiment was conducted to study sex specific total haemocytes count (THC) of mud crab, Scylla serrata (Forskâl, 1775) during the month of August, 2019 from the estuary of river Subarnarekha, West Bengal, India. The quantitative analysis of haemocytes has shown that THC of adult female (2.94×10⁷± 0.15 cells/ml) is higher than that of adult male (1.89×10⁷± 0.11cells/ml). The higher THC count in female seems to be associated with the reproductive functions in female.
