“…Os dados de conversão alimentar obtidos neste estudo diferem dos descritos por Webb & Gatlin (2003), ao avaliarem níveis de 35 e 45% de PB e formas de proteína (intacta e suplementada com aminoácidos) para "red drum" (Sciacrops ocellatus). Divergem ainda dos resultados obtidos por Berge et al (2002), em estudo com salmão-doatlântico, no qual avaliaram as exigências de lisina e arginina e notaram melhora na conversão alimentar dos peixes alimentados com a dieta suplementada com aminoácido sintético.…”

“…Engin & Carter (2001), em estudo com juvenis de enguia (Anguilla australis), observaram aumento da taxa de excreção de amônia com níveis mais altos de proteína na dieta. Os resultados obtidos neste experimento confirmaram os encontrados por Webb & Gatlin (2003), que observaram redução na excreção de amônia em "red drum" alimentados com dietas com menor teor de proteína. Viola & Lahan (1991) observaram menor excreção de nitrogênio pela carpa comum alimentada com dieta contendo 25% de PB em comparação a uma dieta com 30% de PB.…”

“…Information also shows that such protein needs decrease as fish weight increases. Protein ingested by fish is used in maintenance and growth, but when they are overfed only one part of this protein is effectively used for synthesis of new proteins and the remaining is metabolized to produce energy (WILSON, 2002), with an unavoidable increase of nitrogen excretion to the aquatic system (OISHI et al, 2010;WEBB & GATLIN III, 2003). Consequently, when fish are fed with optimal dietary protein levels they retain a proportionally higher amount of protein in the body (growth), decreasing production costs and pollution (THOMAN et al, 1999).…”

“…Ammonia is the dominant end product of nitrogen metabolism in most teleosts, and is toxic at low concentrations, particularly in NH 3 (unionized ammonia) form (CHEW et al, 2006;FELIPO;BUTTERWORTH, 2002;WICKS;. The main internal source of ammonia in fish is through the catabolism of proteins, and most of this waste product is produced in the liver of fish during the transamination of amino acids followed by the deamination of glutamate (WICKS;.…”

“…The main internal source of ammonia in fish is through the catabolism of proteins, and most of this waste product is produced in the liver of fish during the transamination of amino acids followed by the deamination of glutamate (WICKS;. Ammonia is mainly excreted through the gills (WILKIE, 2002), and teleosts usually increase the excretion of ammonia after feeding (ALTINOK;GRIZZLE, 2004).…”
