DENSIDADE DE ESTOCAGEM PARA PRODUÇÃO DE ACARÁ-BANDEIRA EM VIVEIROS ESCAVADOS EM POLICULTIVO COM CAMARÃO-DA-AMAZÔNIA

Abstract

O objetivo deste estudo foi avaliar o desempenho de acará-bandeira (Pterophyllum scalare) produzidos em diferentes densidades em gaiolas no sistema semi-intensivo instaladas em viveiros em policultivo com camarão-da-amazônia (Macrobrachium amazonicum). Foram testados 4 tratamentos (1; 2; 3 e 4 peixes.10 L-1) em dois viveiros escavados, com 4 repetições cada, em um total de 16 unidades experimentais. Os parâmetros de qualidade de água ficaram dentro do esperado para ambas as espécies. Os dados de desempenho - peso médio, sobrevivência, comprimento padrão, conversão alimentar, fator de condição alométrico, biomassa e uniformidade do lote foram submetidos à ANOVA e as receitas brutas de cada tratamento foram calculadas. Os peixes produzidos na menor densidade apresentaram maiores valores de peso final e comprimento padrão, e menores valores de biomassa em comparação aos demais tratamentos. A conversão alimentar aparente, sobrevivência, uniformidade do lote e fator de condição não apresentaram diferenças significativas entre os tratamentos. A maior densidade testada produziu mais peixes e gerou maior receita bruta do que os demais tratamentos. Portanto, recomenda-se o uso da densidade de 20 peixes.10L-1 para produção comercial de acará-bandeira em gaiolas em viveiro em policultivo com camarão-da-amazônia.

The aim of this study was to evaluate the production of Freshwater Angelfish (Pterophyllum scalare) in different stocking densities in cages polycultured with Amazon River Prawn (Macrobrachium amazonicum). Four treatments were evaluated (1; 2; 3 and 4 fish. 10 L(-1)) using two ponds and 24 experimental units. Water quality parameter reached adequate levels for the species. Production data were submitted to ANOVA. Fish produced in the lowest density showed higher values of final weight and standard length, and lower total biomass in comparison with the others treatments. Feed conversion rate, survival, batch uniformity and body factor were not significant different among treatments. The highest density tested produced more fish and gross yield than the others treatments. The density 20 fish. 10L(-1) is recommended to produce Freshwater Angelfish in cages polycultured with Amazon River Prawn.
