Rusaini, . and Owens L., . A simple technique to stage the moult of Penaeus monodon. pp. 1-11. ISSN 0116-6514
Abstract
Growth in crustaceans and other arthropods is interrupted by cyclical moults in which the old cuticle or exoskeleton is shed and in the intervening growth phases the soft tissue swells and a new elastic cuticle gradually thickens and hardens. Marine prawns Penaeus monodon from a commercial farm in northern Queensland Australia were studied alive to assesstheir growth and moulting stages. The median part of the setae of inner uropods was examined by light microscopy. A finely graded classification of five stages and substages of postmoult stage A consisting of substages A1 and A2 and stage B (1-16 hours); intermoult stage C (1 day); premoult stage D consisting of substages D1 D2 and D3/D4 (2-12 days) and ecdysis stage E (about one minute) are described and illustrated. Ecdysis took place at night. Rapid and repetitive moult staging in individual prawns can be carried out without sacrificing the prawns.
