%X The reproductive biology of nine species of aspidochirote holothurians from the majour communities of the New Caledonian lagoon has been analysed. The data were obtained from monthly sampling from 1978 to 1982 of their populations on reef slopes and passes for #Holothuria nobilis$, #H. fuscogilva$, #H. fuscopuctata$ and #Thelenota ananas# in the inner lagoon for #Stichopus variegatus$, #H. scabra$ and #H. scabra versicolor$ and on reef flats for #Actynoptyga mauritiana$, #A. echinites$ and #H. atra$. The morphology and anatomy of the gonads and their annual cycle are described. The reproductive cycles, composed of the five phases of gonad growth, maturing, spawning, post spawning and resting, were determined from the changes in the sexual stages, the gonad indices and the percentage of indeterminate sex. Three main reproductive patterns are recognized, annual cycles with spawning occuring during the warm season or during the cool season and a semiannual cycle. (D'après résumé d'auteur)
