AbstractThe jundiá or silver catfish (Rhamdia quelen Quoy & Gaimard, 1824) is species native to the Americas, omnivorous, with a tendency towards carnivorous feeding habits. The species presents commercial potential, and therefore, knowledge on its nutritional requirements, as well as basic feed ingredients, is essential. Its tendency towards carnivorous feeding habits leads to some concerns regarding plant ingredient digestion abilities, although rice, soybean, flax, sorghum, ground corn or oat bran can be used as feed ingredients for this species, since they present good digestibility coefficients. In order to guarantee adequate performance of metabolic, immunological and reproductive functions, jundiá feed can be supplemented with micronutrients that minimize the effects of antinutritional factors present in plant ingredients. Plant ingredients present several economic advantages such as suitable quality, competitive prices and the fact that they are widely available in South Brazil.
