Biofloc technology is being applied increasingly in shrimp aquaculture. Many countries have adopted this technology to increase shrimp aquaculture production. Owing to its major importance, this study was conducted to identify the bacterial population from biofloc aquaculture shrimp pond water of Singkir Laut, Kedah, Malaysia. Samples of mature biofloc were collected from the biofloc pond water at different shrimp ages (day of culture [DOC]): DOC30, DOC60 and DOC90. Overall, 43 sequences of bacterial species were blasted, which were identified as Exiguobacterium spp., Bacillus spp., Vibrio spp., Acinetobacter junii, Cobetia marina, Rheinheimera aquimaris and Pseudoalteromonas spp. These bacterial species were identified mostly from heterotrophic plate count agar. The bacterial species of Exiguobacterium aestuarii, Exiguobacterium profundum and Exiguobacterium aurantiacum were identified with 16S rRNA gene sequence similarities of 98.45–99.44%. Bacterial species of Bacillus pumilus, Bacillus velezensis, Bacillus cereus, Bacillus safensis and Bacillus subtilis were identified with 16S rRNA gene sequence similarities of 98.81–99.21%. Bacterial species of Vibrio diazotrophicus, Vibrio diabolicus, Vibrio natriegens and Vibrio harveyi were identified with 16S rRNA gene sequence similarities of 98.03–99.19%. Bacteria from Rheinheimera aquimaris were also identified with 16S rRNA gene sequence similarities of 98.69–99.26%; this bacterium is a novel bacterium identified from biofloc samples of the present study and has not been reported from biofloc samples in any previous study. Exiguobacterium spp. from the novel strains of E. aestuarii and E. profundum were identified as dominant, with 23 of 43 samples isolated from a shrimp pond at time points DOC30, DOC60 and DOC90; these bacteria are Gram‐variable rod‐shaped organisms that are capable of producing extracellular enzyme activity to break down chemical structures, thereby helping to remove organic compounds from aquaculture waste. Exiguobacterium spp. are usually identified in tidal flat sediments and on muddy sea coasts. This discovery is consistent with the site of the shrimp pond near to a muddy beach area, which might be the source of seawater leading to the predominance of this type of bacteria in the biofloc samples in the studied pond.

“…Members of Exiguobacterium isolated from different sources, have been associated to the production of cellulases, amylases, xylanases, and ligninases ( González-Escobar et al, 2020 ) as well as the production of the shell component chondroitin ( Bhotmange and Singhal, 2015 ), and have been shown to have potential probiotic functions ( Cong et al, 2017 ). Different strains have been used as probiotics in several invertebrate species, including the shrimp, P. vannamei , improving their growth and survival ( Sombatjinda et al, 2014 ; Kim et al, 2022 ) or the abalone Haliotis iris ( Tuterangiwhiu, 2015 ; Grandiosa et al, 2018 ).…”

Growing knowledge of the host-microbiota of vertebrates has shown the prevalence of sex-specific differences in the microbiome. However, there are virtually no studies assessing sex-associated variation in the microbiome of cephalopods. Here we assess sex-specific variation in the common octopus (Octopus vulgaris) skin microbiome using amplicon sequencing targeting the V4 hypervariable region of prokaryote 16S rRNA genes. Skin and mantle-associated mucus was collected from wild adult individuals of common Octopus (Octopus vulgaris) (9 males and 7 females of similar size). There were no significant differences in the alpha diversity of microbial communities associated with skin or mantle mucosa between sexes. However, our results clearly indicate that adult octopus males and females have a distinct microbial community composition in both skin and mantle associated mucus communities, with female microbiome being dominated by Firmicutes (48.1%), while that of males contained a majority of Proteobacteria (60.5%), with Firmicutes representing only 3.30%, not finding significant differentiation in the microbial communities between the tissues explored. The dominance of different taxa in the skin of O. vulgaris females and males (e.g., Mycoplasmatales and Lactococcus in females and Rhizobiales and Rhodobacteriales in males) suggests a sex-specific symbiosis in which those microbes benefit from easy access to distinct substrates present in female and male skin, respectively. Given the lack of differences in size between specimens of both sexes in this study, we hypothesize differences in hormone profile, as well as behavioral or ecological differences between sexes in the wild, as the main drivers of microbiome differentiation between sexes. Most knowledge of cephalopod microbiota is limited to the digestive tract and the reproductive system. However, cephalopod skin is an organ with a plethora of functions. This is a first attempt to characterize cephalopod skin microbiota and determine sex influence on it.

“…Diferent prebiotic substances such as inulin, beta-glucans, mannan oligosaccharide, spirulina, and diferent yeasts have proved to be benefcial for fsh immune systems while providing extra beneft in enhancing growth [24][25][26]. Spirulina (Arthrospira platensis), a type of bluegreen algae, has been known to improve the gut microfora of aquatic animals when used at an optimum level [27,28] and improve water quality by reducing nitrogenous substances [29]. Spirulina has high crude protein content and is rich in vitamins, minerals, and diferent bioactive compounds, and supplementation in lower amounts in fsh feed can act as a growth promoter [30].…”

The purpose of this study is to compare the effects of probiotics, prebiotics, and their synergism against antibiotics on the growth performance and hematology of Nile tilapia (Oreochromis niloticus). The study was designed by using five treatments over 75 days in which TCon (control), TAnt (antibiotics: Cotrim vet), TPro (commercial probiotics: pond care), TPre (prebiotics: spirulina), and TSyn (synbiotic: probiotic and prebiotic) were used. All the treatments showed significant ( P < 0.05) improvements in growth and feed utilization parameters. The highest mean final growth was found in TSyn (13.79 ± 0.11) and then in TPre (13.61 ± 0.02), TPro (13.22 ± 0.12), TAnt (10.04 ± 0.7), and TCon (8.89 ± 0.19). Weight gain and specific growth rate were significantly ( P < 0.05) different between treatments. The food conversion ratio varied significantly ( P < 0.05) across treatments and the lowest value was observed in TPro (1.13 ± 0.021). The protein efficiency ratio (PER) was significantly ( P < 0.05) different between treatments and the highest value was in TPro (3.1 ± 0.05). The survival rate was not significantly ( P < 0.05) different between treatments. The highest white blood cell (WBC) counts were found in TSyn (12.63 ± 0.11) followed by TPre (12.6 ± 0.2), TPro (12.32 ± 0.12), TCon (12.16 ± 0.105), and TAnt (11.03 ± 0.46). The values of red blood cells and platelets were not statistically significant ( P < 0.05) among the different treatments. However, all treatments showed normal hepatocyte structure in liver tissue histology, and intense hepatic lipid vacuoles in TSyn indicated improved growth. The higher growth performance and feed utilization values were observed in probiotics, prebiotics, and their synergism units compared to antibiotic treatment. Therefore, probiotics, prebiotics, and their synergism can be used as an alternative to antibiotics in tilapia aquaculture.
