Ultrastructure of the Y-organ of Astacus astacus (L.) (Crustacea) in relation to the moult cycle.

H Birkenbeil, M Gersch.   

Abstract

The electron microscopical investigation of Y-organs of Astacus astacus revealed that during intermoult (stage C) the cytoplasm is poorly developed and that it increases at premoult (stage D). It then shows the typical signs of steroid production, namely agranular endoplasmic reticulum and mitochondria of the tubular type. Furthermore, a larger type of mitochondria with a regular pattern of internal structure is described.
