Abstract

The polyculture models with Brazilian native species, curimatã-pacu (Prochilodus argenteus) and freshwater prawn (Macrobrachium acanthurus) in different stocking densities was analyzed. One hundred fifty one juveniles of P. argenteus and 259 freshwater prawns with initial average weight of 15.22 ± 2.25 g and 4.03 ± 0.88 g, respectively, were randomly distributed into 16 concrete ponds, with daily renewal rate of water of 20%. The experiment was conducted from April to June 2012, in a completely randomized design, with four treatments [proportion between fish (F) and prawn (P)]: 3.5F:0P; 3.5F:5P; 3.5F:8P and 3.5F:11P, with four replications. The results indicated that the increasing the density of prawn to 3.5F:5P and 3.5F:11P negatively influenced the fish performance, except its survival.
