“…Several studies have shown that the BFT system can enhance the productive performance of sh. This is because the microorganisms present in the bio oc system become bioavailable as a complementary food source (Silva et al 2019;Dos Santos et al 2021, 2023aPires et al 2022). The study found that the performance of juvenile matrinxã in the two production systems evaluated was mainly related to the formation of microbial ocs in the BFT system.…”

“…The bio oc system can achieve a balance between protein, lipids, and ash in food (Crab et al 2012;Marinho-Pereira et al 2020). The production of microorganisms in the system is affected by the type of feed and the crude protein level of the diets (Pires et al 2022). The study shows that the nutritional composition of the animals was not affected by the production system.…”

This study evaluated potential for rearing the matrinxã, Brycon amazonicus, under different crude protein (CP) levels, using production performance, water quality and animal welfare as indicators. To achieve this, 720 juvenile fish (3.65 ± 0.17 g) were distributed across 24 experimental units (200 L) and fee study lasted 60 days. The study followed a factorial design (2x4), with two production systems: Biofloc technology (BFT) and clear water (CW), and four levels of crude protein (CP = 24%, 30%, 36%, and 42%) in the diet, with three repetitions for each. The study found that the BFT system showed a lower total ammonia level. However, the production system did not have any effect on pH or nitrite concentration. Oxygen levels were found to be lower in the 42% CP group. Fish produced in the BFT exhibited better performance of apparent feed conversion, productivity, and survival. The production system affected total leukocytes and neutrophils in the blood. There was no significant difference in carcass crude protein content and the ether extract content was higher in the animals from the BFT system. Nutritional composition of the biofloc showed differences for ash, with lower levels in the 42% CP treatment. In conclusion, juvenile matrinxã can be fed a diet containing 30% CP in both production systems. Furthermore, the results demonstrated that biofloc did not confer a direct benefit to matrinxã juveniles in terms of their feeding, however BFT represented a promising alternative for increasing the survival and improved animal welfare during the rearing phase.

“…Porém os autores não deixam informações relevantes quanto ao custo de aeração, que pode inibir a rentabilidade econômica do possível estudo, sem uma avaliação prévia do consumo de oxigênio pelas bactérias degradadoras de matéria orgânica no sistema, onde na qual foi obtida um volume superior de 1000 mg/l de sólidos, acima do recomendado para operação sustentável do sistema com uso de tecnologia de bioflocos. Pires et al (2022) buscaram avaliar os efeitos de níveis de proteína sobre o desempenho zootécnico, parâmetros hematológicos e bioquímicos, índices somáticos e rendimentos de carcaça e filé de juvenis de pacu (Piaractus mesopotamicus) criados em sistema de bioflocos. Cinco dietas experimentais foram formuladas com níveis crescentes de proteína bruta (PB) sendo 194, 232, 278, 316 e 359 g.kg-1.…”

O objetivo do presente estudo foi investigar por meio de revisão sistemática científica informações publicadas em periódicos sobre a temática de utilização da tecnologia de bioflocos em formas jovens de peixes. Buscou-se examinar de forma qualitativa e quantitativa documentos relacionados ao assunto adotado, coletados na base de dados da Scopus e Web of Science, no período de 2015 até o período de maio de 2023. Compreendeu-se que trabalhos científicos que envolvam tecnologias intensivas de produção com intuito de reduzir o uso de recursos hídricos e espaços de terra necessários para a atividade, podem ser trabalhados em maior escala experimental, através de parceiras com empresas e propriedades privadas, como são denotadas em instituições de pesquisa no exterior. Conclui-se apesar do assunto ser relativamente recente no domínio da pesquisa cientifica, proponha-se novas pesquisas com parcerias e acompanhamento técnico-científico, que possam ser realizadas com base no uso sustentável da tecnologia de bioflocos aplicada de forma econômica e social na piscicultura.
