A single farmed fish species assimilates about 20% of the nutrients in the supplied diet. This study evaluated if the culture of complementary ecological-function species can recover nutrients dispersed into water and transform them into high-valued biomass. A completely randomized experiment was designed with three treatments and four replications of each production system: monoculture of lambari (Astyanax lacustris); integrated aquaculture of lambari and Amazon river prawn (Macrobrachium amazonicum); and integrated aquaculture of lambari, Amazon river prawn, and curimbata (Prochilodus lineatus). Fingerlings of lambari (0.8 +/- 0.8 g) were stocked in twelve earthen-ponds (0.015 ha) at the density of 50 fish m(-2). Eight ponds were stocked with juveniles of Amazon river prawn (1.1 +/- 0.2 g) at the density of 25 prawn m(-2). Four of these eight ponds were stocked with curimbata fingerlings (0.2 +/- 0.1 g) at a density of 13 fish m(-2). Only lambari was fed twice a day with an extruded commercial diet. The experiment lasted 60 days when lambari attained commercial size. The inclusion of prawn increased the total species yield from 1.8 to 2.4 t ha(-1) cycle(-1) and reduced the feed conversion ratio (FCR) from 2.5 to 1.8. The inclusion of prawn and curimbata increased the total yield to 3.2 t ha(-1) cycle(-1) and reduced the FCR to 1.4. Therefore, the integrated culture of lambari, prawn, and curimbata improves the use of space, water, feed, and benthic species to recover the large quantity of nutrients accumulated in the bottom of lambari pond production, converting them into high-nutritional and monetary-valued biomass.
