The Tambaqui fish Colossoma macropomum (Cuvier, 1816) , is a typical species from the amazon state, which the cultive to find oneself in ascendance, mainly with the increase of the post-larval production. This work has as objetive to determine the effect of the colors in the post-larval survival to the tambaqui fish during the incubation phases. The experiment was realized with the support a hatchery with the 60L of capacity, in the pisciculture station of Balbina, Amazon State, Brazil. The experiment was formed with four conditions and five replies to each. In the three conditions the hatcheries were envolved with cellophane sheets with differents colors and the last conditions the hatchery wasn’t envolved. Each condition was represented by a color : A- blue; M- brown; P- black and T- translucent (environmental light). To the experiments was obtained any effect of the colors on the fertilization (F(3;16) = 0,53, p > 0,05). However, the larval eclosion was influenceated by the colors: the “T” and “A” conditions presented the better performance (F(3;16) = 4,65, p < 0,05). The rate of the post-larval prodution was influenced by the colors too: the “T” and “M” conditons presente better income (F(3;16) = 4,76, p < 0,05). Thus is possible to suggest that in some phases of the fish reprodution was influenceated by the colors.
