The X-organ-sinus gland complex in the eyestalk of decapod crustaceans is their principal endocrine center (Fingerman, 1987). One of the hormones secreted by this neuroendocrine complez is the crustacean hyperglycemic hormone or CHH. This hormone has been isolated from several species and then purified and sequenced (Keller, 1992). The relevant stimuli for its secretion and the mechanisms of action of this hormone have already been reported (Santos and Keller, 1993). Although the presence of CHH in the estuarine crab Chasmagnayhus granulata is well known (Nery et al, 1993), this hormone has not been purified yet in this crab…..
