Abstract: O principal objetivo deste trabalho foi determinar a exigência de proteína digestível (PD) para a tilápia do Nilo na fase de reversão sexual, onde foram utilizadas 1250 larvas distribuídas em 25 aquários (60L), com cinco tratamentos e cinco repetições em um delineamento inteiramente casualizado. As larvas foram alimentadas com rações isoenergéticas, isocálcicas e isofosfóricas, contendo 30, 34, 38, 42 e 46% de PD e 30 mg/kg do hormônio a-metil testosterona. O arraçoamento foi realizado à vontade, cinco vezes a… Show more

“…In general, animals fed 55% CP diets presented the worst performance, a fact that is confirmed by the air (Table 3). These results are in accordance with the ones recorded by Hayashi et al (2002) who observed a decrease in growth and survival for crude protein levels over 43% on this species larviculture.…”

“…Nile tilapia, contrary to several species which need live food, may be fed exclusively with formulated diet from the first feeding (Sanches & Hayashi, 1999;Toyama et al, 2000;Hayashi et al, 2002;Meurer et al, 2005;Boscolo et al, 2008), thus facilitating its larviculture.…”

“…The initial phase of fish farming is important due to its influence on the other stages (Hayashi et al, 2002); appropriate growth is directly reflected in broodstock formation (Navarro et al, 2010). In the initial phase of broodstock formation, the use of additives that promote maximum growth (Traesel et al, 2011) can be an important management strategy.…”

“…A quantidade de proteína da dieta depende de inúmeros fatores inerentes ao peixe, às condições ambientais de criação e à própria dieta. Vários estudos têm buscado o melhor regime de alimentação quanto à qualidade e aos níveis proteicos, com o objetivo de redução dos custos com alimentação, sem causar danos metabólicos aos peixes (Al Hafedh, 1999;Hayashi et al, 2002;Furuya et al, 2005;Botaro et al, 2007;Righetti et al, 2011;Loum et al, 2013).…”
