Effect of enzymatic complex in the diet of pirarucu, Arapaima gigas juveniles [PDF]
Acta Amazonica, 2021 ABSTRACT The pirarucu, Arapaima gigas is a native, carnivorous fish species from the Amazon basin. As carnivorous fish have low amylase activity, exogenous enzymes can improve the digestibility of carbohydrates in aquaculture feeds. We evaluated the digestibility of increasing levels of an enzymatic complex in diets of pirarucu juveniles (65.2 ± 0.4 g).
