As feed accounts for a significant proportion of a farm’s expenditure, animal nutrition is one of the key profit determinants. Attributed to the size-dependent market value, enhancing shrimps' growth is essential to maximize profit. Despite not being the best option, antibiotics are often used as growth-promoting agents in farming. Although this trend is less explicit in aquaculture, increasing production yield is paramount, especially when intensive aquafarming compromises animal growth and increases disease prevalence. However, the environmental and clinical pitfalls of indiscriminate antibiotic usage are surfacing. Fortunately, increasing evidence demonstrated probiotics as a safer, more sustainable, and environmental-friendly substitute for antibiotics. Nonetheless, most studies are observational, and the growth-promotion mechanisms of these agents are yet to be elucidated. In this light, this review aims to decipher the growth promotion mechanisms of probiotics in shrimps based on the primary works conducted. Evidently, probiotic treatment modulates the gut microbiome composition. The growth promotion effect of probiotics is partly mediated through the production of bioactive compounds such as short-chain fatty acids, vitamins, and polyamines. Besides, elevated digestive enzyme activities following the introduction of probiotics may help enhance digestibility and utilization. Histological changes at the hepatopancreas and intestine were evident. Furthermore, probiotics may reinforce the protective mechanisms in the gut and strengthen immune function. Treated shrimps demonstrate better appetite and exhibit superior metabolic and growth-related genes profile. Contrasting these recognized mechanisms with antibiotics helps construct the initial framework for designing high-quality probiotics for growth enhancement in farmed animals.

“…Nevertheless, the widespread use of antibiotics leads to the appearance and emergence of resistant bacteria and affect the aquatic environment (water and sediment contamination) (Caruffo et al, 2015;Medina et al, 2020;Makridis et al, 2021). Recently, probiotics have emerged as a good and effective alternative to ban or minimize the antibiotic use and control diseases (Balcazar et al, 2007;Meidong et al, 2017;Emam and Dunlap, 2020). Probiotics are defined as live microorganisms which beneficially affect the health of the host when consumed in adequate concentrations (Fuller, 1989;FAO/WHO/OIE, 2006;Pinto et al, 2020).…”

“…A large number of bacteria are classified as probiotics, but the most widely used in aquaculture are Lactobacillus and Bacillus. However, Bacillus species have attracted much more attention due to non-toxic and nonpathogenic compound production and their sporulation ability, which gives them protection against stressed conditions (heat, gastrointestinal tract (GIT) compared to other probiotics (Barbosa et al, 2005;Cao et al, 2019;Kuebutornye et al, 2019;Emam and Dunlap, 2020;Amoah et al, 2021). To exert and endure the benefits of probiotics within the host, several properties should be investigated for probiotic strain screening, including antagonism against fish pathogens, being kept alive in GIT, resistance to storage conditions, secretion of exogenous enzymes, and being safe (Fuller, 1989;Muñoz-Atienza et al, 2014;Cao et al, 2019;Zhou et al, 2019;Ghanei-Motlagh et al, 2020).…”

Probiotic properties of Bacillus strains isolated from the gastrointestinal tract against pathogenic Vibriosis

Vibriosis is one of the major diseases leading to massive fish mortality. Probiotics may provide a potential alternative method to protect fish from pathogens and to promote a balanced environment minimizing the use of antibiotics and chemotherapy. The aims of this study were to (i) isolate and purify marine spore-former strains from Sardine and shrimp intestine, (ii) screen for bacteria with potential probiotic properties, and (iii) carry out their in vitro safety assessment using a subtractive procedure. Among 108 spore-former strains, five strains exhibited a strong antibacterial activity against Vibriosis such as Vibrio harveyi and Vibrio anguillarum. These selected strains were unaffected by high-temperature and gastrointestinal conditions; produced amylase, protease, and lipase activities; and showed high percentages of auto-aggregation and co-aggregation with pathogens, as well as a strong adhesion to fish mucus. Partial 16S rDNA gene sequencing and MALDI-TOF MS revealed that isolates are Bacillus amyloliquefaciens or Bacillus subtilis. All of them were susceptible to antibiotics, while hydrolic enzymes and virulence factors were not detected for B. subtilis S17. In conclusion, based on their proprieties and their safety assessment, B. subtilis S17 could serve as a potential probiotic candidate for aquaculture.
