In intensive production systems, fish are exposed to stressful conditions, becoming more susceptible to diseases, which may reflect on their growth parameters. Alternative growth promotion methods without environmental impacts have become the target of researchers and fish farmers. For this reason, the objective of this work was to evaluate the potential of including Malaysian rubber seed in the feeding of tambacu raised in cages. The seeds were collected on a farm in the municipality of Imperatriz, Maranhão, a sample was sent for physical-chemical analysis of the fixed oil. For inoculation in the diet, the husks were removed, dried at room temperature, crushed and manually mixed with the commercial ration feed following the experimental design. The quality of the water was measured throughout the experiment. Biometric measurements were performed to infer growth gains with the tested diet. The results show an influence on the inclusion of 40% of the Malaysian rubber seed in the tambacu diet during rearing. In order to reduce costs resulting from the use of alternative ration feeds, we suggest the use of Malaysian rubber seed in an attempt to minimize barriers due to the high prices of commercial ration feeds within the fish farming production chain.
Nos sistemas de produção intensiva os peixes são expostos a condições estressantes, tornando-se mais susceptíveis a doenças, o que pode refletir nos seus parâmetros de crescimento.Métodos de promoção de crescimento alternativos sem impactos ambientais tem se tornado alvo de pesquisadores e piscicultores. Por este motivo,o objetivo deste trabalho foi avaliar o potencial de inclusão de semente da seringa na alimentação de tambacu criados em tanque-rede. As sementes foram coletadas em uma fazenda no município de Imperatriz, Maranhão, uma amostra foi encaminhada para análise físico-química do óleo fixo. Para a inoculação na dieta, as cascas foram removidas, secas em temperatura ambiente, trituradas e misturadas manualmente com a ração comercial seguindo o delineamento experimental. A qualidade da água foi aferida durante todo o experimento. As aferições biométricas foram realizadas para inferir os ganhos de crescimento com a ração testada.Os resultados demonstram influência na inclusão de 40% da semente de seringa na dieta de tambacu durante a recria. Com o objetivo de redução de custos que resulta do uso de rações alternativas, sugere-se então a utilização da semente de seringa na tentativa de minimizar os entraves pelos altos preços das rações comerciais dentro da cadeia produtiva da piscicultura.
