Conteúdo:	The yellow-spotted amazon river turtle, Podocnemis unifilis, is one of the most consumed species in the Amazon region. However, the basic zootechnical parameters of its production in captivity are not yet fully established to support a sustainable breeding system. Thus, the objective of this study was to investigate the effect of stocking density on the growth and feeding of Podocnemis unifilis in captivity. A total of 112 females of the species were used for 120 days, housed in 16 polyethylene water tanks with a capacity of 1000 L, containing 250 L of water, with 40% dry area and 60% flooded area. The animals were fed extruded commercial fish feed with 28% crude protein (CP), in the amount of 0.5% live weight, for five days per week. A randomized block experimental design was used, with four treatments (stocking densities of 16 animals/m³, 24 animals/m³, 32 animals/m³ and 40 animals/m³), and four replicates each, totaling 16 experimental units. divided into two blocks (accommodation). The growth of Podocnemis unifilis was not influenced by different stocking densities; however, there was an effect on the use of food by the animals and on fat accumulation. The study showed that the higher the density in the P. unifilis cultivation (up to 40 animals/m³) the greater the proportion of animal body fat.
