      Abstract

      The aim of this study was to assess the feasibility of integrated multi-trophic culture of Nile tilapia (Oreochromis niloticus) and Amazon River prawn (Macrobrachium amazonicum) in brackish water by evaluating its limnological characteristics and economic performance. The experiment was completely randomized with four treatments and four repetitions: control treatment with Nile tilapia only, stocked with 2 tilapias/m² (P2C0) and three integrated multi-trophic culture treatments stocked with 2 tilapias/m² and prawns at densities of 4, 8 and 16 prawns/m² (P2C04, P2C08 and P2C16, respectively). The limnological variables of temperature, pH, dissolved oxygen, turbidity, ammonia, orthophosphate and chlorophyll "a" were evaluated and throughout the experiment remained within the limits recommended for culture. The experiment lasted 150 days with monthly animal sampling. No significant differences were observed for total fish biomass or for fish and prawn total survival rates. However, prawn individual weight decreased as stocking density increased. Gross revenue was not significantly different between treatments, as well as profitability. The profitability was 40.1% (P2C0), 36.7% (P2C04), 41.2% (P2C08) and 50.1% (P2C16). It is concluded that although feasible from the view point of husbandry, the integrated multi-tropic culture of M. amazonicum and O. niloticus did not influence significantly profitability compared to the monoculture system.

      O objetivo deste estudo foi verificar a viabilidade do cultivo multitrófico integrado da tilápia-do-nilo (Oreochromis niloticus) e do camarão-da-amazônia (Macrobrachium amazonicum) em água salobra, mediante a avaliação de suas características limnológicas e de seu desempenho econômico. O experimento foi inteiramente ao acaso, com quatro tratamentos e quatro repetições: tratamento controle somente com tilápia-do-nilo, estocado com duas tilápias/m² (P2C0) e três tratamentos de cultivo multitrófico integrado, estocados com duas tilapias/m² e camarões nas densidades de quatro, oito e 16 camarões/m² (P2C04, P2C08 e P2C16, respectivamente). As variáveis limnológicas temperatura, pH, oxigênio dissolvido, turbidez, amônia, ortofosfato e clorofila "a" foram avaliadas e, durante todo o experimento, mantiveram-se dentro dos limites recomendados para o cultivo. O experimento durou 150 dias, com amostragem mensal dos animais. Diferenças significativas não foram observadas para a biomassa total de peixe nem para a taxa de sobrevivência total em peixes e camarões. Entretanto, o peso individual do camarão diminuiu à medida que a densidade de estocagem aumentou. A receita bruta não foi significativamente diferente entre os tratamentos, assim como a rentabilidade. A rentabilidade foi 40,1% (P2C0), 36,7% (P2C04), 41,2% (P2C08) e 50,1% (P2C16). Conclui-se que, apesar de viável do ponto de vista da larvicultura, o cultivo multitrófico integrado de M. amazonicum e O. niloticus não influenciou significativamente a rentabilidade quando comparado com o sistema de monocultura.
