“…Physicochemical parameters are a relevant issue for fish farms as variations can have a negative effect on fish (Qin et al, ). Fortunately, these remained within the optimum ranges for S. lalandi (Chávez‐García, ; Njoku et al, ), which suggests that the filtration systems and good cultivation practices used helped maintain an adequate sanitary state during the study.…”

The bacteriological water quality associated with marine fish farming systems can be a determining factor in the development of disease, and understanding this quality is fundamental for the prevention and control of possible disease outbreaks. In the present study, the bacteriological water quality of a yellowtail amberjack Seriola lalandi broodstock maintenance system, composed of two units of a recirculation aquaculture system (RAS 1 and RAS 2), was determined. From February 2016 to January 2017, monthly samples of surface water were taken at six points in the two RAS systems: (a) from the water reception tank and (b) from filter 1 and (c) tank 1 (in RAS 1) and (d) filter 2 and (e) tank 2 (in RAS 2) and from a joint (f) discharge point. The bacteriological quality was determined by counting total heterotrophic bacteria (THB) and by molecular identification (16S rRNA gene). The number of THB showed a tendency to decrease in filters 1 and 2, to increase in tanks 1 and 2, and again increase in the discharge. The fluctuation of THB, in general, was from 1.0 × 103 to 2.9 × 105 CFU/mL. In total, 102 colonies were isolated, corresponding to nine orders and 52 species, and Vibrionales and Alteromonadales were the most abundant orders. The bacterium Vibrio harveyi, a pathogen of S. lalandi, was identified, as were other bacterial species that are known pathogens; however, no signs of disease or mortality events were recorded during the study. These results suggest that the bacterial community contributed to the maintenance of a balance in the RAS, which prevented the development of infectious diseases. Furthermore, the physicochemical parameters (temperature, oxygen, nitrogen compounds, and alkalinity) were maintained within the optimum range required by S. lalandi. Some zoonotic bacteria were found, as well as bacteria with probiotic and industrial uses. These results represent the first report on bacteriological quality in RAS for S. lalandi.

“…Proteobacteria is reported to be very common in aquaculture ponds in the most of the earlier reports (Qin et al 2016;Rud et al 2017;Zhou et al 2017). Due to their role in global carbon, nitrogen and sulphur cycle, abundance of 50-61% Proteobacteria have been described to be appropriate in the wetland ecosystem to ensure the optimum growth of aquatic animals (Ansola et al 2014;Cardona et al 2016).…”

This study aimed to characterize the bacterial communities in rearing water treated with commercial plastic biological ball filters named as Bio‐ball in marron culture for 60 days. Inclusion of Bio‐ball in the aquaculture tanks showed improvement in water quality parameters and enrichment of bacterial communities in terms of operational taxonomic units. The water treated with Bio‐ball showed significantly less nitrate, nitrite, ammonia, phosphorus and high dissolved oxygen concentration than untreated control group. At phylum level, Proteobacteria was dominant in both control and treated water, whereas Firmicutes was found to be significantly (P < 0·05) enriched in Bio‐ball treated water. Among the classified genus, Aquabacterium and Polunucleobacter were most dominant in control and Bio‐ball treated water respectively. Linear Discriminant Analysis Effect Size exhibited 31 indicator bacterial genus, 10 in control and 21 in treated condition, suggesting the enrichment of microbial lineages with addition of Bio‐ball. The bacteria Haliscomenobacter, Hypnocyclicus, Pajaroellobacter and Vibrio were found to be significantly (P < 0·001) correlated with higher pH, nitrate, nitrite, phosphorus and ammonia in control tanks, whereas Corynebacterium was linked to higher temperature in treated water. Overall results suggest that Bio‐ball filter media significantly improved the water quality and microbial populations in aquaculture tanks. Significance and Impact of the Study The results of this study revealed the positive impacts of Bio‐ball in enrichment of microbial flora associated with the degradation process of nitrogenous and organic compounds. Bio‐ball also showed the capability to prevent the colonization of harmful bacteria, and favoured the growth of beneficial microbes in aquatic system. This study therefore could pave the ways of increasing the aquaculture production by improving the water quality.

“…Such ponds are also exposed to various anthropogenic and natural activities giving rise to different carbon sources. Previous studies have found that the water quality as well as microbial community of pond is effected by carbon source [19]. In natural ecosystems, physiochemical conditions such as pH, soils type, temperature, salinity and other organic contents have high impact on metabolic activity and distribution of microbiota [20].…”

44Metagenomic analysis holds immense potential for identifying rare and uncharacterized 45 microorganisms from many ecological habitats. Actinobacteria have been proved to be an 46 excellent source of novel antibiotics for several decades. The present study was designed to 47 delineate and understand the bacterial diversity with special focus on Actinobacteria from pond 48 sediment collected from Sanjeeviraya Hanuman Temple, Ayyangarkulam, Kanchipuram, Tamil 49 Nadu, India. The sediment had an average temperature (25.32%), pH (7.13), salinity (0.960 50 mmhos/cm) and high organic content (10.7%) posing minimal stress on growth condition of the 51 microbial community. Subsequent molecular manipulations, sequencing and bioinformatics 52 analysis of V3 and V4 region of 16S rRNA metagenomics analysis confirmed the presence of 40 53 phyla, 100 classes, 223 orders, 319 families and 308 genera in the sediment sample dominated by 54 56(1.63%). Among the Actinobacteria phylum, Acidothermus (29.68%) was the predominant genus 57 followed by Actinospica (17.65%), Streptomyces (14.64%), Nocardia (4.55%) and Sinomonas 58 (2.9%). Culture-dependent isolation of Actinobacteria yielded all strains of similar morphology 59 to that of Streptomyces genus which clearly indicating that the traditional based technique is 60 incapable of isolating majority of the non-Streptomyces or the so called rare Actinobacteria. 61 Although Actinobacteria were among the dominant phylum, a close look at the species level 62 indicated that only 15.2% within the Actinobacterial phylum could be assigned to cultured 63 species. This leaves a vast majority of the Actinobacterial species yet to be explored with 64 possible novel metabolites have special pharmaceutical and industrial application. It also 65 indicates that the microbial ecology of pond sediment is neglected fields which need attention. 66 67 metabolites 68 It is estimated that only 1% of microbes in the natural environment are culturable under 70 laboratory conditions [46]. More than 88% of culturable isolates belong to four phyla known as 71 Proteobacteria, Firmicutes, Actinobacteria, and Bacteroidetes [47]. However, uncultivated 72 bacteria possess a great diversity of enzymes adaptable to different environmental conditions 73 which could serve as a prolific source of novel bioactive compounds with industrial and 74 pharmaceutical applications. Metagenomics is a tool to study massive microbial communities 75 prevailing in the environment in its natural state irrespective of its uncultivable properties. This 76technique has not only helped to overcome the barriers of culture dependent techniques but also 77 identified rare microorganisms [23]. It also provides a wide and unbiased view of the potential 78 microbial functions in a single snapshot with high resolution contributing immensely to the 79 global microbial diversity studies from different ecosystem and their potential ecological 80 functions [27]. On the other hand, there have been several reports on the widespread distribution...
