“…It is important that the producer knows this information to implement biosecurity measures for personnel in charge of fish management. On the other hand, bacterial species belonging to the genera Alteromonas , Bacillus , Microbacterium , Pseudoalteromonas , Pseudomonas , Shewanella , Streptococcus, and Vibrio have been used as probiotics in aquaculture (Aranda et al, ; Leyton et al, ; Martínez‐Cruz, Ibáñez, Monroy‐Hermosillo, & Ramírez‐Saad, ; Xue et al, ). At the species level, V. lentus was found, which is considered a probiotic and antagonist to V. harveyi in the culture of sea bass D. labrax (Schaeck et al, ), as well as V. proteolyticus , considered a probiotic for turbot S. maximus (De Schrijver & Ollevier, ), and M. algicola , used as an adjuvant in vaccines for gilthead sea bream S. aurata (Montero et al, ).…”

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.

“…Therefore, bacteria isolated from healthy flounder (gills, intestines and skin mucus) were chosen for screening QQ activities in our work and some QQ strains could be developed to probiotics to control disease in aquaculture. One of the mucus derived isolates was P. prydzensis Th125, and mussel related isolates in this species have recently been described to bear antibacterial activity against several vibrios48. Another mucus derived strain Muricauda olearia Th120 had cellular appendages, and it is suggested that the appendages are required for connection of cells and adhesion to surfaces49.…”

Quorum sensing (QS) is a population-dependent mechanism for bacteria to synchronize social behaviors such as secretion of virulence factors. The enzymatic interruption of QS, termed quorum quenching (QQ), has been suggested as a promising alternative anti-virulence approach. In order to efficiently identify QQ bacteria, we developed a simple, sensitive and high-throughput method based on the biosensor Agrobacterium tumefaciens A136. This method effectively eliminates false positives caused by inhibition of growth of biosensor A136 and alkaline hydrolysis of N-acylhomoserine lactones (AHLs), through normalization of β-galactosidase activities and addition of PIPES buffer, respectively. Our novel approach was successfully applied in identifying QQ bacteria among 366 strains and 25 QQ strains belonging to 14 species were obtained. Further experiments revealed that the QQ strains differed widely in terms of the type of QQ enzyme, substrate specificity and heat resistance. The QQ bacteria identified could possibly be used to control disease in aquaculture.

“…Thus, it has been demonstrated that Pseudoalternomonas sp. strains DIT09, DIT44 and DIT46 isolated from Peromytilus purpuratus showed bacteriostatic anti-Vibrio parahaemolyticus activity [15] but their in vivo effects have not been tested yet. In a similar way, Roseobacter sp.…”
