Efeito da frequência alimentar no crescimento de juvenis de bijupirá Rachycentron canadum criados em tanques tipo "near-shore"
Palavras-chave:
manejo alimentar, desempenho zootécnico, peixe marinhoResumo
O desempenho de juvenis de bijupirá Rachycentron canadum (15,7 ± 0,4 g; média ± DP) criados em tanques-rede de 1 m³, em uma baía protegida, 24,0 ± 2,1°C, alimentados com ração comercial brasileira (45% de proteína bruta e 16% de gordura) até saciedade aparente, fornecida em uma (F1), duas (F2) e três (F3) refeições por dia, durante 30 dias, foi avaliado. A densidade de estocagem inicial foi de 0,6 kg m-3. O desempenho de produção de juvenis de bijupirá foi afetado significativamente pela frequência alimentar. Grupos alimentados duas e três vezes ao dia apresentaram crescimento maior e mais eficiente do que os grupos F1. Não houve diferença entre os tratamentos F2 e F3 para o ganho em peso (15,6 ± 1,5 g e 16,3 ± 2,0 g, respectivamente), taxa de crescimento específica (TCE: 2,3 ± 0,3% e 2,5 ± 0,4% do peso corporal diário, respectivamente) e conversão alimentar aparente (CAA: 2,3 ± 0,2 e 2,5 ± 0,3, respectivamente). No entanto, os tratamentos F2 e F3 promoveram melhores resultados comparados ao tratamento F1 (ganho em peso: 8,4 ± 1,1 g; TCE = 1,4 ± 0,2%; CAA = 3,2 ± 0,6) (p<0,05). O coeficiente de variação foi inversamente proporcional ao aumento da frequência alimentar. Não houve diferença significativa para taxa de sobrevivência, sendo superior a 90% em todos os tratamentos. Este trabalho sugere que o desempenho do crescimento de juvenis de bijupirá criados em condições do presente estudo pode ser otimizado quando alimentados duas vezes ao dia, facilitando os procedimentos de criação e minimizando os custos relacionados com mão-de-obra e embarcação.
