Abstract : An experiment was carried out to evaluate the effects of brine shrimp nauplii (#Artemia# sp.), Cladocera (#Moina# sp.), Tubifex worms and a trout starter diet on growth performances and survival rate of Mekong catfish larvae (#Pangasius bocourti# Sauvage, 1880). Larvae accepted all four types of experimental diets, owing to large mouth opening at the first feeding (0.6-1.0 mm at 45° and 90° mouth opening, respectively). Artemia nauplii and Tubifex worms resulted in the same growth performances and survival rates for a 9-d nursing time with specific growth rates of 36-37 %.d-1 and survival rates of 92-93 %. #Moina# led to a lower growth performance (31 %.d-1) but the survival rate (94 %) was not significantly different to that of larvae fed #Artemia# nauplii or #Tubifex# worms. Trout starter feed, dry pellet, proved relatively less suitable for larval rearing of #P. bocourti# owing to a low survival rate (68 %) and growth performance (21 %.d-1). The study confirmed the feasibility of completely replacing #Artemia# nauplii by #Tubifex# worms. (Résumé d'auteur)
