“…The results of this study indicate that the microbial community associated with the treatments was represented by 17 classes in water and gut samples, of which those with the highest relative abundance were: Alphaproteobacteria (Phylum Proteobacteria), Betaproteobacteria (Phylum Proteobacteria), Gammaproteobacteria (Phylum Proteobacteria), Actinobacteria (Phylum Actinobacteria), Flavobacteria (Phylum Bacteroidetes) and Sphingobacteria, but the Class Alphaproteobacteria and Betaproteobacteria were those with the highest relative abundance in all treatments, which coincides with a study carried out with shrimp culture in biofloc, reported by Addo et al (2021). These results agree with those reported by Kim et al (2021), who evaluated the effect of wheat flour on the microbial composition in the water of a biofloc system with shrimp ( L. vannamei ) culture and found that the members of the phyla with the highest relative abundance were Proteobacteria, Bacteroidetes, and Actinobacteria, which coincides with the results of this study.…”

The prawns fed with Lactococcus lactis obtained 100% survival in the BFT and BFTPROB treatments compared to the CONT (80%). Regarding growth, it was observed in PROB and BFTPROB treatments, the organisms got greater weight (6.3 ± 1.6, 6.8 ± 1.3 respectively) compared to the other treatments. The effect of L. lactis in the bacterial community of Macrobrachium rosenbergii postlarvae (PL's) with initial mean weight of 0.1 g, and length 1.4 cm in biofloc, was evaluated. A randomized experimental design was used: T1:BFT: biofloc; T2:BFTPROB:biofloc+probiotic; T3:PROB:probiotic; T4:CONT:control; all in triplicate with 60 PL's/treatment. On days 64 and 127, the weight and length of prawns were determined. 15 guts/treatment were extracted and water samples to obtain bacterial DNA. Massive sequencing of 16S rRNA gene of the samples was performed. Metagenomic analysis identified 17 bacteria classes in gut and water samples. The most abundant were Alphaproteobacteria, Gammaproteobacteria, Betaproteobacteria, Flavobacteria, Actinobacteria, and Clostridia with different benefits in the prawns' health. The bacterial community in the intermediate phase was different to the final, maybe for the colonization capacity of certain bacteria that developed in each treatment. However, L. lactis did not affect the microbial community in prawns' gut and culture water, it attributed to the displacement of the microbial community in biofloc and other probiotics, however it was observed a better prawns' growth and survival with biofloc and probiotic treatments.

“…Generally, highly diverse bacterial community including 18-40 phyla were observed in waterbody of biofloc systems raising P. vannamei (Baliga et al, 2021; Ferreira et al, 2021; Huerta-Rabago et al, 2019; Vargas-Albores et al, 2019), with a Shannon index as high as 5.31-7.23 (Addo et al, 2021; Chen et al, 2019; Gao et al, 2019; Huang et al, 2021; Jiang et al, 2020; Kim et al, 2021; Pilotto et al, 2018). Similarly, in the present study, 30 phyla were observed in both treatments with a Shannon index of 6.14-6.77.…”

This study aimed to investigate the effects of substrate on water quality, shrimp growth and bacterial community in the biofloc system with a salinity of 5‰. Two treatments, biofloc system with (sB) or without (nB) addition of elastic solid packing filler (nylon) as substrate, were set up. Penaeus vannamei postlarvae (PL, ~ stage 15) were stocked at a density of 4000 PL m-3 in each treatment with triplicates for a 28-days culture experiment, taking glucose as carbon source (C:N 15:1). Results showed that the survival rate (96.3±3.6%), FCR (0.76±0.06) and productivity (1.54±0.12 kg m-3) in sB treatment were significantly better than those in nB treatment (81.0±7.1%, 0.98±0.08 and 1.14±0.09 kg m-3, P<0.05). All water parameters were in the recommended ranges without significant effect from substrate (P > 0.05), except TSS, turbidity, biofloc volume, pH and carbonate alkalinity (P < 0.05). Actinobacteria (4.0-22.7%), Bacteroidetes (10.4-33.5%), Firmicutes (0.2-11.2%), Planctomycetes (4.0-14.9%) and Proteobacteria (29.4-59.0%) were the most dominant phyla for both treatments. However, the bacterial community in sB treatment showed to be significantly different from that in nB treatment (Jaccard distance 0.94±0.01, P=0.001). Substrate showed significant effects on Shannon, Heip, Pielou and Simpson index, as well as relative abundances of Actinobacteria, Bacteroidetes and Planctomycetes (P < 0.05). The results suggested that addition of substrate affected the shrimp growth, water quality and bacterial community in the biofloc system nursing P. vannamei PL with a 5 ‰ salinity.

“…Fusobacteriaceae, aeromonadaceae and moraxellaceae were enriched in the pond environment compared to the tank environment. Microorganisms in sediment were mainly related to the enzymes of organic matter decomposition (Dai et al, 2021), which served as a natural nutritional supplement to enhance aquatic organisms' growth (Addo et al, 2021). The nutritional supplement is closely related to the growth development of aquatic animals.…”

The environment microbiome affects the growth and development of fish species. Information of the environment microbiome is beneficial to increase the production of fish in different aquaculture systems. In this study we analyzed differences in environmental microbial composition, intestinal metabolites and differentially expressed genes (DEGs) in American shad living in tank aquaculture and pond aquaculture environment. The results demonstrated that the dominant phyla were Bacteroidetes, Actinobacteria, Fusobacteria, Gemmatimonadetes, Firmicutes, Acidobacteria, Nitrospirae and Epsilonbacteraeota in two different environments. There were significantly changed of metabolites in different aquaculture environment, including DP-ethanolamine, L-proline, sulfuric acid, L-valine, L-tryptophan, creatinine, uric acid and L-isoleucine. The transcriptome data revealed eight genes (As23G026314, As04G005148, As21G024434, As04G005193, As23G026314, As13G016035, As02G001872 and As07G009244) related to metabolisms significantly changed in pond aquaculture group compared to tank aquaculture group. In addition, the body weight, amino acid metabolism, and glycerophospholipid metabolism of American shad also significantly changed in the pond aquaculture environment. Therefore, identifying the predominant microbiome in the aquaculture environment may be prevent the disease from occurring and maintain healthy fish reared in the aquaculture environment.
