Resumo

Os currais de mangue foram modificados para produzir caranguejo-da-lama (Scylla serrata) e peixe-leite (Chanos chanos) em sistema de policultivo. A modificação dos currais de mangue foi feita adicionando escavações dentro do curral. Os parâmetros de qualidade da água (oxigênio dissolvido (OD), pH, salinidade e temperatura) foram monitorados e avaliadas as taxas de recuperação e produção em cada curral. O experimento foi conduzido durante um período de criação de 143 dias em nove currais de mangue, cada um com área de 32 m2 e altura líquida média do recinto de 3 m da superfície do solo. Os três diferentes currais construídos (projeto existente: apenas canal, 43% de escavação por área e 54% de escavação por área) foram designados como T1, T2 e T3, respectivamente. Os parâmetros de qualidade da água registrados nos currais foram favoráveis ao crescimento e recuperação do caranguejo-da-lama e do peixe leiteiro, com exceção do DO. Para o caranguejo-da-lama, a maior recuperação média foi registrada no T2, seguida do T3, e a menor no T1. A taxa de produção seguiu o mesmo padrão da recuperação, sendo T2 a mais elevada, seguida de T3 e T1 a mais baixa. A análise estatística revelou que as variações na recuperação do caranguejo da lama não foram significativas, enquanto em termos de taxa de produção, os currais de mangais modificados foram considerados mais eficazes do que o projecto existente. Devido à mortalidade total do peixe leiteiro cultivado, a actual configuração de currais de mangais modificados foi considerada inadequada para o sistema de policultura de produção de peixe leiteiro e caranguejo da lama.
