Indicadores zootécnicos e econômicos da tilapicultura em tanques-rede de diferentes dimensões

Abstract

Objetivou-se, com o presente estudo, comparar os principais indicadores zootécnicos e econômicos da tilapicultura em sistema superintensivo, desenvolvido em tanques-rede com duas diferentes dimensões: 6 e 18 m3. Foram utilizados 12.960 juvenis machos revertidos de tilápia-do-nilo (Oreochromis niloticus), linhagem supreme, com peso médio inicial de 32,0 g (± 0,85) para os tanques de 6 m3 e 88,5 g (± 0,96) nos tanques de 18 m3. Os peixes foram alimentados três vezes ao dia com ração extrusada comercial, teor de proteí­­na bruta de 40 a 32%, granulometria de 2 a 8 mm e taxa diária de alimentação iniciando com 8% do peso vivo (PV) e decrescendo até 1% do PV. Concluiu-se que, embora não diferindo da maioria dos indicadores zootécnicos (P>0,05), a produção de tilápias em tanques-rede de maior dimensão proporcionou menor custo total médio e maior retorno lí­­quido médio por kg do pescado produzido, 34,4% superior, resultando em maior rentabilidade.
