“…A study reported that the addition of scFOS (short-chain fructooligosaccharides) in various doses given in various feed ratios improved daily growth rate in L. vannamei (Li et al 2007). A recent research revealed that the dietary administration of poly-b-hydroxybutyrate (PHB) stimulates the immune parameters, digestive enzymes, and provides protection to L. vannamei against Vibrio attack (Kiran et al 2019). Another study was conducted with MOS addition as prebiotic that can promote the growth of Verrucomicrobiaceae and Actinobacteria, which promotes the recovery of the intestinal epithelial barrier functionality and produce secondary metabolites like antimicrobial factors and growth promoters in L. vannamei (Gainza & Romero 2020).…”

The microbiome of the host and its surroundings play a vital role in its health and well-being. Unlike the terrestrial organisms that maternally acquire its microbiome, the aquatic species mainly get colonized by the microorganisms in its aquatic surrounding and are exposed to a wide variety of microbial community based on the type of aquatic environment the host inhabits. This review is focused on the aquaculture and shrimp microbiome and factors that influence its microbiome such as prebiotics, probiotics, synbiotics, diet, stress conditions, frequency and type of antibiotics used, host physiological conditions and developmental stages. This review also casts light on the role of the microbiome in enhancing the shrimp health, immune response, microbial colonization, and the effects of the biofloc system on shrimp and aquaculture microbiome. Moreover, beneficial microbes can be a safer alternative to harmful antibiotics used in aquaculture, which can thereby prevent the emergence of superbugs and also enhance the production rate. A proper understanding of the interactions between the host and its microbiome can help us to modulate and manipulate the aquaculture microbiome to enhance the health of aquatic organisms, which ensures the growth of the aquaculture industry. Therefore, the treatment strategies should be targeted towards the modulation of shrimp and aquaculture microbiome, which acts as beneficial partners to overcome the challenges confronted by the aquaculture sector.

“…However, the rapid deterioration of aquaculture environments [8][9][10] and frequently occurring aquaculture diseases [11][12][13] are important factors in restricting and hindering the development of the aquaculture industry [14]. The safety of L. vannamei products is closely related to human health [12,13,15,16]. For example, aquatic catches, such as L. vannamei, may deteriorate during fishing and sales, affecting the quality of the associated products and causing potential food health risks [1,17].…”

“…However, for the continued expansion of the aquaculture scale [ 6 ], improvements in intensive aquaculture are needed [ 7 ]. However, the rapid deterioration of aquaculture environments [ 8 , 9 , 10 ] and frequently occurring aquaculture diseases [ 11 , 12 , 13 ] are important factors in restricting and hindering the development of the aquaculture industry [ 14 ]. The safety of L. vannamei products is closely related to human health [ 12 , 13 , 15 , 16 ].…”

“…For example, white spot syndrome virus (WSSV) [ 11 ], yellow head virus (YHV) [ 20 ], monodon baculovirus (MBV) [ 21 , 22 ], Taura syndrome virus (TSV) [ 23 ], hepatopancreatic parvovirus (HPV) [ 24 ], infectious hypodermal, and hematopoietic necrosis virus (IHHNV) [ 24 ] are viruses of Penaeus. Notably, some clinical pathogenic Vibrio species, such as Vibrio cholerae [ 25 ], Vibrio parahaemolyticus [ 12 , 13 ] and Vibrio vulnificus [ 26 , 27 ], which exist in or parasitize the tissues of L. vannamei , are also important human pathogenic bacteria [ 28 , 29 , 30 , 31 , 32 ]. Many studies have shown that intestinal bacteria influence several aspects of animal health [ 33 ], including feeding, growth, pathogen defense, energy metabolism, reproduction, immunity, and aging [ 34 ], in crucial ways.…”

“…The output of L. vannamei cultured in seawater from the coastal areas of China, an important area of concentrated L. vannamei aquaculture, reached 1.14 million tons in 2019 [ 49 ]. Some of the bacteria associated with shrimp diseases are of concern [ 12 , 50 , 51 ]. Conversely, studies on the intestinal microflora of healthy L. vannamei under different culture conditions and growth stages have also been performed [ 52 , 53 ].…”

Intestinal bacteria are crucial for the healthy aquaculture of Litopenaeus vannamei, and the coastal areas of China are important areas for concentrated L. vannamei cultivation. In this study, we evaluated different compositions and structures, key roles, and functional potentials of the intestinal bacterial community of L. vannamei shrimp collected in 12 Chinese coastal cities and investigated the correlation between the intestinal bacteria and functional potentials. The dominant bacteria in the shrimp intestines included Proteobacteria, Bacteroidetes, Tenericutes, Firmicutes, and Actinobacteria, and the main potential functions were metabolism, genetic information processing, and environmental information processing. Although the composition and structure of the intestinal bacterial community, potential pathogenic bacteria, and spoilage organisms varied from region to region, the functional potentials were homeostatic and significantly (p < 0.05) correlated with intestinal bacteria (at the family level) to different degrees. The correlation between intestinal bacteria and functional potentials further suggested that L. vannamei had sufficient functional redundancy to maintain its own health. These findings help us understand differences among the intestinal bacterial communities of L. vannamei cultivated in different regions and provide a basis for the disease management and healthy aquaculture of L. vannamei.
