“…On the contrary, in treatments with BFT, the decrease in DO can be attributed to the development of heterotrophic microbial communities, which use it for their metabolic activities (Piñeiros-Roldan et al 2020, Gálvez-Cantero et al 2022. Likewise, Faizullah et al (2015) indicate that these communities' oxygen consumption is very high, reaching more than 70% of total oxygen consumption. The pH of the water tended to be more acidic in the BFT groups compared to the control group.…”

The effect of live yeast Rhodoturula glutinis was evaluated on juvenile Oreochromis niloticus cultivated in a Biofloc system. Growth performance and the expression of innate response and relevant oxidative stress genes were evaluated after a 12-week feeding trial. Three experimental treatments were evaluated in a conventional tilapia culture (control), Biofloc culture (BFT), and Biofloc with the addition of the live yeast R. glutinis 1×106 CFU g-1 (BFT+Rg), with four replicates per treatment. In all cases, commercial food was supplied to the organisms (32% protein and 5% lipids). O. niloticus juveniles (7.02 ± 0.04 g) were randomly distributed in 12 tanks, each with 15 animals. BFT+Rg treatment showed a significant increase in weight gain compared with the other treatments. Significant improvements were found in Fulton's condition factor, feed conversion rate, and hepatosomatic index under Biofloc conditions, BFT, and BFT+Rg treatments. No significant differences were observed in survival. R. glutinis directly influenced gene expression in the liver and intestine. The expression of tnfa, tgfb, hsp70, and gpx, genes in the liver significantly increased in the BFT+Rg treatment compared with the other treatments. Similarly, a significant increase was found in intestinal il1b, tnfa, tgfb, trf, hsp70 gpx, and cat expression patterns in the BFT+Rg treatment. Based on the performance and immune response, the present study suggests the use of R. glutinis as a strategy to increase the productivity of tilapia in Biofloc culture.

“…Azim and Little (2008), registered a 10% higher final weight and 30% lower feed conversion ratio for the BFT versus a clear water culture for juvenile nile tilapia Oreochromis niloticus. Moreover, the species Carassius auratus showed even better results from the productive point of view; the average final weight of animals grown in BFT was 53% higher than the animals reared in the control treatment (Faizullah et al, 2015).…”

Geophagus brasiliensis is a species native from Brazilian continental waters and it is distributed in several aquatic ecosystems. Despite its importance to artisanal fishing, mainly for riverside communities, and fishkeeping, this species is an unusual resource for aquaculture. Fish farming can be carried out in different systems, as in biofloc system (BFT), which has some advantages comparing to traditional semi-intensive systems: high densities, maximizing the use of water and food provided. The objective was to evaluate the rearing of the G. brasiliensis in a BFT comparing with a clean water system (CW), considering the zootechnical performance, water quality and microorganisms community. The experiment lasted 40 days and was carried out in tanks with a useful volume of 200 L, with three repetitions for each treatment. To compare the two systems, the fish conditions (weight-length ratio, condition factor and zootechnical performance) and the conditions of the environment (water quality and composition of microorganisms in the BFT treatment) were evaluated. BFT animals showed higher zootechnical performance (final weight, weight gain and feed conversion) when compared to treatment CW. The water quality showed a difference between BFT and CW for all levels except temperature and N-ammoniacal; however, it was within the acceptable limits for cichlids in the two treatments. Eight rates of microorganisms, potential food for the fish, were found in the BFT treatment during the experiment. The species G. brasiliensis showed a higher zootechnical performance in a biofloc system compared to the clear water system, indicating the potential for cultivation in intensive production systems.

This study aimed to evaluate the development and the increase in the skin pigmentation of the organism Heros severus cultured in a biofloc system with diets enriched with carotenoid pigments. The culture was made in 80 L water tanks with 20 juvenile organisms of H. severus; each treatment was made by duplicate. Four experimental diets were used: a) trout feed, El Pedregal®; b) TetraColor®; c) carrot and d) beetroot. The diet that obtained the highest values regarding the growth of the fish was the control diet. Regarding the coloration of the fish, the beetroot diet was the diet that presented the highest values with 9.55 μg of total carotenoids in tissue, presenting significant differences (P = 0.001) concerning the other diets, proving that a diet based on beetroot can be a good option for the culture of ornamental fish. Because it allows the organisms to have a survival rate above 90%, have similar growth to the control group, and a significant improvement in coloration, being a natural carotenoid low-cost source to improve the commercialization of organisms. Nevertheless, it did not present significant differences (P = 0.005) regarding beetroot and TetraColor® diets, while it presented significant differences with the carrot diet.
