Willfiihr-Nast J., H. Rosenthal, P. J. Udo, F. Nast, Aquar. Living Resour., 1993, 6, 115-137. Larvae of the African River Prawn Macrobracltium vollenlzovenii, indigenous to West Africa, were reared at various salinities (0-32°/00). A salinity range of 16-24°/00 was found most suitable with highest survival and growth, and lowest number and duration of instars. Freshwater was lethal already to zoea I -larvae. A mass culture experiment demonstrated the aquaculture potential of this Macrobrachium species. Larval rearing to postlarvae was possible applying the same methods as for M. rosenbergii. Detailed descriptions of rearing techniques are provided.Keywords: Prawns, Palaemonidae, Macrobrachium vollenhovenii, larval rearing, mass culture, salinity studies, egg incubation, survival, growth, larval and postlarval development. ~l e z a~e en laboratoire et etudes expCrimentales des elfers de la salinirk sur le dkoeloppement larvaire de la crevette de riviire africaine Macrobrachium vollenhovenii (Decapoda, Palaemonidae).Les larves de la crevette de riviere africaine Macrobrachiunr collenhovenii, espice indigene d'Afrique de I'Ouest, ont ete elevks a differentes salinites (0-32 O/,,). Une gamme de salinites de 16-24 O/oo a ete consideree la plus appropriee pour des taw; de croissance et de survie les plus importants, et pour des mues dont le nombre et la duree sont les plus faibles. L'eau douce etait deja letale pour les larves au stade zoe-I. Une ex+rience de culture en masse demontra la potentialite de I'aquaculture de cette espece de Macrobrachium. L'elevage larvaire jusqu'aux postlarves etait possible en appliquant les memes methodes pour M. rosenbergii. Des descriptions detaillees des techniques d'elevage sont donnees.
