Brazil major probiotics and bioremediators have proven their effectiveness in the cultivation of exotic species. The aim of the study was to evaluate the effects of a commercial multi-species probiotic suitable for shrimp and fish in the feed and as biocontrol in tambaqui rearing through zootechnical performance, water quality, clinical and laboratory alterations and innate immunity evaluations. Colossoma macropomum juveniles were used, distributed: Control (C)—without any probiotic addition; Probiotics added to water (G2)—.004 g/L of probiotics added to each experimental unit; Probiotics in feed (G3)—5 g/kg of probiotics added to the feed. The use of probiotics during the tambaqui breeding phase was proven safe. However, the use of multi-species did not result in any complementary benefit when added to the water or to the feed for 60 consecutive days regarding zootechnical performance, water quality and tambaqui health under the applied experimental conditions. The findings demonstrate the need for further in vitro and in vivo tests regarding microorganism screening and protocols analyses for each culture species, since several factors influence the effects of the administration of probiotics on aquaculture production and health.

多物种益生菌管理对 Colossoma macropomum 幼鱼饲养的影响：补充和生物修复

巴西主要的益生菌和生物修复剂已证明其在外来物种培育方面的有效性。该研究的目的是通过畜牧学性能、水质、临床和实验室改变以及先天免疫评估，评估适用于饲料中的虾和鱼的商业多物种益生菌的效果，以及在坦巴基饲养中作为生物防治的效果。巨果使用、分布的幼鱼：对照（C）——没有添加任何益生菌；添加到水中的益生菌（G2）——每个实验单元添加的益生菌0.004 g/L；饲料中的益生菌 (G3)——在饲料中添加 5 g/kg 的益生菌。在 tambaqui 育种阶段使用益生菌被证明是安全的。然而，在应用的实验条件下，当连续 60 天将多物种添加到水或饲料中时，在畜牧性能、水质和 tambaqui 健康方面没有产生任何互补的好处。研究结果表明，需要对每种养殖物种进行微生物筛选和方案分析的进一步体外和体内测试，因为有几个因素会影响益生菌对水产养殖生产和健康的影响。
