“…Overall, the effects of probiotics on feeding have been little examined to date and remain unclear. In tambaqui (133), fish fed probiotics ( Bacillus subtilis ) and control diets have similar feeding ratios, and probiotics induce a reduction in appetite in zebrafish [ Lactobacillus rhamnosus (38)] and an increase in food consumption in pacu [ B. subtilis (134)]. The discrepancies in results are likely due to variations in the nature and doses of probiotics used.…”

The microorganisms within the intestinal tract (termed gut microbiota) have been shown to interact with the gut-brain axis, a bidirectional communication system between the gut and the brain mediated by hormonal, immune, and neural signals. Through these interactions, the microbiota might affect behaviors, including feeding behavior, digestive/absorptive processes (e.g., by modulating intestinal motility and the intestinal barrier), metabolism, as well as the immune response, with repercussions on the energy homeostasis and health of the host. To date, research in this field has mostly focused on mammals. Studies on non-mammalian models such as fish may provide novel insights into the specific mechanisms involved in the microbiota-brain-gut axis. This review describes our current knowledge on the possible effects of microbiota on feeding, digestive processes, growth, and energy homeostasis in fish, with emphasis on the influence of brain and gut hormones, environmental factors, and inter-specific differences.

“…The use of Bacillus subtilis and Bacillus cereus as probiotics for fish is known to enhance growth and the assimilation of nutrients, by improving the activity of digestive enzymes, besides boosting the animals’ immune system (Azevedo et al., 2016; Nakandakare et al., 2013; Wild et al., 2014). In addition, B. subtilis has known bactericidal and fungicidal effects, as it may increase the immune responses of the host (Ramesh & Souissi, 2017).…”

This study aimed at evaluating the effects of a probiotic additive in productive performance and physiological parameters for Rhamdia quelen. The fish were fed diets containing increasing levels of the additive (0.15; 0.30; 0.45; and 0.60 g/kg of feed), which consisted of a blend of Bacillus cereus and B. subtilis, both at the concentration of 4 × 10 11 CFU). Productive performance parameters were higher in fish fed diets containing 0.60 g/kg of the probiotics. Both the proximate composition and carcass yield were affected when 0.30 and 0.60 g/kg of the additive was included, whilst serum biochemical parameters were higher in fish fed diets containing 0.60 g/kg of the additive. An increase in the hepatic oxidative stress activity was found when 0.30 g/kg was supplied. The development of intestinal villi was influenced by the inclusion of the additives, as well as the activity of mucous-secreting cells in the tissue. Hepatocyte's growth was differential in fish fed diets containing 0.30 g/kg and other tissue alterations were found using 0.60 g/kg of the additive. The inclusion of 0.60 g/kg of the probiotic in diets for R. quelen enhances its growth performance and physiological status.

The silver catfish (Rhamdia quelen) became one of the most studied native species by presenting expressive growth, excellent feed conversion, tolerance to handling, high carcass yield and reproductive viability when reared in captivity (Amaral-Junior et al., 2008; Barcellos et al., 2004; Carneiro et al., 2006). In addition, its high acceptance in the consumers market has increasing the number of rearing facilities, which can be performed either in excavated ponds or net-cages, from the initial stages to termination, presenting optimal growth throughout all year, even during periods of low tem

RESUMO Objetivou-se avaliar diferentes granulometrias do milho (GM) em rações para juvenis de tambaqui sobre o desempenho zootécnico, composição da carcaça e viabilidade econômica. Foram distribuídos 160 peixes (3,86±0,03 g) em 20 aquários (40 L), em delineamento inteiramente casualizado com cinco tratamentos e quatro repetições. Os tratamentos consistiram de rações com diferentes GM: 150, 300, 500, 710 e 850 µm. Como parâmetros de desempenho zootécnico foram avaliados: consumo de ração (CR), ganho de peso (GP), conversão alimentar (CA), comprimento total final (CTF), comprimento padrão final (CPF), altura final (ALT), taxa de crescimento específico (TCE), taxa de desenvolvimento específico (TDE) e sobrevivência (SOB). Para composição de carcaça foram avaliados umidade, proteína bruta, extrato etéreo e matéria mineral. Na análise econômica das rações, foram analisados o custo médio com ração por quilograma de peso vivo ganho (CMR), o custo total de produção (CTP) e o índice de eficiência econômica (IEE). Os dados obtidos foram submetidos à análise de variância em nível de 5% de probabilidade e regressão polinomial. Verificou-se comportamento quadrático para as variáveis CR, GP, CA, TCE, TDE, CTF, CPF e ALT, obtendo-se os melhores resultados, respectivamente, para GM estimadas em 530,22; 555,40; 597,47; 566,75; 562,07; 557,48; 562,70 e 555,68 µm. Não houve influência das GM sobre a composição da carcaça. Verificou-se comportamento quadrático para as variáveis CTP e CMR, com valores mais altos para GM estimadas em, respectivamente, 600,44 e 602,11 µm. Conclui-se que granulometria do milho de 500 µm é indicada zootecnicamente e economicamente para rações de juvenis de tambaqui.
