Crustaceans have a cyclic phenomenon, moulting, for development and growth that is not encountered in most other groups of aquaculture animals. Biochemical and physiological changes in various tissues of crustaceans occur during the moult cycle. Changes to the immune components of prawns in association with moulting have also been studied to a lesser extent. Hematological variation in both total hemocyte count (THC) and differentiated hemocyte count (DHC) was recorded in individuals and between species during the moult cycle. In the current investigation, we characterized the different...
