  abstract = {{T}he aim of this study was to compare the effects of dry and moist diets at weaning on growth, survival and incidence of cannibalism in the {A}mazon catfish {P}seudoplatystoma punctifer. {T}hree moist diets ({MCD}: moist commercial diet; {MCPD}: moist commercial peptide enriched diet; {BLD}: bovine liver enriched diet) and a dry diet ({CDD}: commercial dry diet) were used to feed fingerlings reared in 40-{L} tanks (30-{L} water volume; three replicates per treatment; stocking density: initial 1500 larvae per tank, from 18 days post-fertilization, dpf (17 days post-hatch, dph) onwards 210 juveniles per tank; photoperiod 0{L}:24{D}) in a recirculation water system (27.9 +/- 0.5 degrees {C}). {F}ish were fed {A}rtemia nauplii at 20% of the larval biomass from 4 to 19days post-fertilization (dpf) and then weaned onto the four experimental diets within 3days in the moist diets and within 6days in the dry diet. {A}t 33 dpf, feeding of groups fed the moist diets was switched to the dry diet within 2days. {R}esults showed higher (58.6 +/- 10%) and lower (4.7 +/- 0.7%) survival rates in {BLD} and {CDD} groups, respectively, the latter showing the highest occurrence of type {II} cannibalism. {A}lthough weaning was achieved in all dietary groups, the moist diets {MCD} and {MCPD} showed better growth results both in terms of total length and wet weight. {T}his study showed that, among the tested diets, the moist diets seem to be more adequate for early juvenile {P}.punctifer.},
