  abstract = {{T}wo feeding experiments were carried out on #{P}angasius hypophthalmus$ larvae reared in a recirculating water system during 8 days. {T}he first experiment was done at the {C}an {T}ho {U}niversity ({V}ietnam) and the second at the {RIFF} {S}ukamandi station ({I}ndonesia). {T}he main objective of the first experiment was to compare survival and growth peformance of #{P}. hypophthalmus$ larvae fed with either #{M}oina$ sp. or #{A}rtemia$ nauplii and with either strong or moderate aeration. {S}trong aeration was tested in order to homogenise prey repartition in the water column, since #{A}rtemia$ and #{M}oina$ sp. tended normally to be concentrated in corners or at the bottom of the tanks. {T}wo feeding rates (150 and 4000% of fish biomass) were tested. {T}he second experiment aimed at an evaluation of optimal feeding level with #{A}rtemia$ nauplii, by considering growth, number of ingested preys and survival rates of larvae. {E}ach of three feeding levels ({R}1, {R}2 and {R}3) were tesed at three different fish stocking densities (10, 30 and 90 larvae/{L}). {T}he feeding level {R}1 was adjusted daily according to a pre-established model of the number of #{A}rtemia$ ingested as a function of age in #{P}. hypophthalmus$ larvae. {T}he rations {R}2 and {R}3 were respectively 3 and 9 times greater than {R}1. {T}he prey asscessibility (number of prey per litre), which varied as a function of the different combinations of feeding level x fixh stocking density, was also considered as a parameter that could influence larval growth and survival. {T}he results of the first experiment indicated that both #{A}rtemia$ and #{M}oina$ sp. could be used as a first feed for #{P}. hypophthalmus$ larvae. {H}owever, larvae fed #{A}rtemia$ nauplii presented a faster growth rate than those fed #{M}oina$. {P}erturbation of the rearing media by strong water aeration resulted systematically in reduced larval survival rates, whatever the type of prey and feeding rate used...
