Polyculture of curimatã-pacu (Prochilodus argenteus) and canela shrimp (Macrobrachium acanthurus) feed with dehydrated cassava leaf meal
ABSTRACT Polyculture systems are integrated cultivation systems where two or more aquatic species are maintained at the same place using locally available ecological resources. The purpose of this study was to analyze the zootechnical performance of curimatã-pacu (Prochilodus argenteus) when polycul...

ABSTRACT Polyculture systems are integrated cultivation systems where two or more aquatic species are maintained at the same place using locally available ecological resources. The purpose of this study was to analyze the zootechnical performance of curimatã-pacu (Prochilodus argenteus) when polyculture with canela shrimps (Macrobrachium acanthurus) and with dehydrated cassava leaf bran comparatively with monoculture. 96 curimatã-pacu fishes (P. argenteus) and 72 canela shrimps (M. acanthurus) were cultivated. At the beginning of the experiment, their average body masses were 10.77 ± 1.29 and 3.68 ± 0.74 g, respectively, randomly distributed in a factorial scheme with a full random experimental design in 24 polyethylene water tanks (70 L) in water recirculation system, comprising two simultaneous factors: curimatã pacu monoculture (4 fishes: 0 shrimps per tank) and curimatã pacu and canela shrimp polyculture (4 fishes: 6 shrimps per tank), was added dehydrated cassava leaf meal (DCLM) to the monocultures and polycultures in different percentages: 0% (treatment 1, T1), 10% (T2) and 20% (T3), with four replicas each.
