Abstract
Setal development and proecdysial cuticular changes can be observed in the pleopods of the American lobster (Homarus americanus) from earliest D0 through stage D3, and with pleopod staging criteria it is possible to follow proecdysis from beginning to end. A technique is described for recognition of all stages and substages of proecdysis, for evaluating effects of various treatments on proecdysis, and for predicting time of ecdysis where holding temperature is known. Histological comparisons between the pleopods and the general integument suggest a universal criterion for stage D2, and a need for adjustment in some accepted molt stage criteria. Development plateaus occur in stage D0 instead of C4 in this species, and this suggests that the concept of stage C anecdysis may be incorrect.
