Resumo: Two experiments were carried out at Instituto de Acuicultura de Los Llanos/Universidad de Los Llanos (Villavicencio, Colômbia) to evaluate first feeding influence on yamú larval rearing. In the first experiment, the following prey types were tested to first feeding for yamú larvae during 24 hours: Artemia sp. nauplii, wild zooplankton and pirapitinga (Piaractus brachypomus) larvae. In the control yamú larvae were subjected to starvation. Pirapitinga larva was the prey item that offered the best results for weight and total length gain (p < 0.05). In the second experiment, yamú larvae performance was compared when stocked into fertilized ponds during 15 days either at the onset feeding or after first feeding with pirapitinga larvae prey item. Survival rate was lower in the larvae that were stocked into rearing ponds at the onset of feeding (13.4%) when compared to survival of yamú larvae that were stocked after receiving pirapitinga larvae (74.1%). These results indicate that the use of pirapitinga larvae at first feeding increases performance of yamú larval rearing.

No experimento 1, testaram-se, durante vinte e quatro horas, diferentes tipos de alimento vivo como primeira alimentação das pós-larvas (PL) de yamú: náuplios de Artemia sp. (NA), zooplâncton silvestre (ZS) e larvas de pirapitinga (LP) (Piaractus brachypomus). No tratamento controle as pós-larvas foram mantidas em jejum. O alimento que proporcionou melhores resultados em ganho de peso e comprimento total foi larvas de pirapitinga (p < 0,05). No experimento 2, durante 15 dias, comparou-se o desempenho na alevinagem de PL - estocadas imediatamente em viveiros após início da alimentação exógena - com aquelas estocadas depois de receber manejo da primeira alimentação com larvas de pirapitinga. Ao final da alevinagem, a sobrevivência do tratamento submetido ao manejo da primeira alimentação foi maior (74,1%) quando comparado com aquele que não recebeu esse manejo (13,4%), indicando que o emprego de larvas de pirapitinga na primeira alimentação no yamú melhora o desempenho na alevinagem.Editora da Universidade Estadual de Maringá2008-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/209210.4025/actascianimsci.v25i1.2092Acta Scientiarum.
