| Abstract | This paper characterizes the molting stages of giant freshwater prawn, Macrobrachium rosenbergii under laboratoryconditions. Using the distal fifth pleopod as the main reference region and applying Drach's classification system, we checkedthe epidermis and carapace hardness and documented major structural changes, such as the retraction of epidermal tissues fromthe cuticle and setal development. Our findings showed that in early postmolt, no development of seta matrix was observed. Acloser examination of seta lumen during the intermolt stage showed that the epidermis was a densely granular structure and theinternal cone was developed. In the premolt stage, a retraction of the epidermis from the cuticle (apolysis) and the formation ofnew seta were recorded. This study shows that using internal seta development changes is apparently a useful, easy, and practicalmethod of determining molting stage in order to facilitate the study of molt-linked processes and metabolism. |
