Three stocking densities (400, 500, and 600 fish m-3) were evaluated for 60 days in a completely randomized design (n=4). There were no significant differences among the stocking densities for growth performance parameters, but yield was higher in the density of 600 fish m-3 (3,909.43±397.79kg m-3) compared to 400 fish m-3 (2,656.43±665.45kg m-3). Glucose, hematocrit, and total plasma proteins levels did not differ among treatments. The production was economically feasible for the three stocking densities. However, the density of 600 fish m-3 showed the highest profit. According to the results, 600 fish m-3 is the most adequate density for the initial grow-out phase of tambatinga in net pens.  aEconomic analysis  aFish culture  aGrowth performance  aPiaractus brachypomus  aColossoma macropomum  aPeixe  aTambaqui1 aLIMA, A.
