Moulting in Crustaceans

INTRODUCTION cast off occurs in all arthropods, from insects to crustaceans, it is inherent for growth, reproduction and metamorphosis. ecdysis occurs in rounds and involves the shedding of the hard exoskeleton to frustrate a softish clean shell, the uptake of water from the animals spry surroundings create the new exoskeleton to expand, and finally the hardening of the new exoskeleton. It is a complex transition that is affected by a undulate of external factors such as temperature, photoperiod, nutrition, and eyestalk ablation. Despite colossal research, the molting process in crustaceans still remains under the weather understood. Microarray technology provides a powerful, holistic approach to study gene expression in relation to changing physiological states. It enables non only the business leader to profile the expression of genes already known to be mired in slough, but besides facilitates the discovery of new, as provided unknown, genes tha t may be important in the moult process. ?Understanding, and wherefore exacting, the process of moulting, has significant capableness for a range of commercialised applications in crustaceans, such as the telephone extension of valuable seafood products. there are three areas within moulting control that lay down been identified as having potential commercial significance: 1.

compulsive the timing of the moult, 2. manipulating the synchrony of moulting within a community or mass moulting, and 3. controlling the process of shell hardening. THE dish up OF CRUSTACEAN molt Moulting is common to all cru staceans and is essential for growth, metamo! rphosis, and reproduction. Moulting is a complex process, affected by a range of environmental cues and regulated by a cascade of hormonal signals involving changes in gene expression, cellular commitment, mitotic and secretory activity, endocrinology, behavior, and cell death. The moult cycle refers to the period between two successive moults and has been subdivided into 4 major stages.
