The nature and the levels of ecdysteroids in hemolymph and ovaries by an enzyme immunoassay using two systems of antibodies reveals the presence of two main hormone: 20- hydroxyecdysone and ecdysone, while the changes in hormonal concentration in hemolymph during the molt cycle shows a single peak that occurred at the beginning of the pre-molt (stage D) and coincides with the apolysis [27, 38].
As in other crustacean species [28, 30, 36, 46, 47], the secretion of the old cuticle continue from stage A until the end of stage C, while during the stage D, we observe the apolysis, the secretion of the new cuticle and the digestion of the old cuticle [7].
