“…Furthermore, the family Vibrionaceae is most often associated with bacterial infection in grouper [10]. V. harveyi has also been referred to as opportunistic bacteria in Lates calcarifer [11], Lateolabrax japonicus [12] and Litopenaeus vannamei [13]. According to previous studies, V. harveyi destroys the tissues on the epidermis and cause skin ulceration called skin ulcer disease [10].…”

Epinephelus coioides, or grouper, is a high economic value fish species that plays an important role in the aquaculture industry in Asia. However, both viral and bacterial diseases have threatened grouper for many years, especially nervous necrosis virus, grouper iridovirus and Vibrio harveyi, which have caused a bottleneck in the grouper industry. Currently, intestinal microbiota can provide novel insights into the pathogenesis-related factors involved in pathogen infection. Hence, we investigated the comparison of intestinal microbiota communities in control group and pathogen-infected grouper through high-throughput sequencing of the 16S rRNA gene. Our results showed that microbial diversity was decreased, whereas microbial richness was increased during pathogen infection. The individuals in each group were distributed distinctly on the PLSDA diagram, especially the GIV group. Proteobacteria and Firmicutes were the most abundant bacterial phyla in all groups. Interestingly, beneficial genera, Faecalibacterium and Bifidobacterium, predominated in the intestines of the control group. In contrast, the intestines of pathogen-infected grouper had higher levels of harmful genera such as Sphingomonas, Atopostipes, Staphylococcus and Acinetobacter. Additionally, we investigated the expression levels of innate and adaptive immune-related genes after viral and bacterial infection. The results revealed that immunoglobulin T and proinflammatory cytokine levels in the intestine increased after pathogen infection. Through these unique bacterial compositions in diseased and uninfected fish, we could establish a novel therapeutic approach and bacterial marker for preventing and controlling these diseases.

“…Refs. [ 35 , 36 ] employed the same strain in Asian seabass ( Lates calcarifer ) and brown-marbled grouper ( Epinephelus fuscoguttatus ), and found significant protection against Vibrio spp. Vaccination induces protection against specific infections by stimulating the immune system to limit and control the infection [ 37 ].…”

Field Efficacy of a Feed-Based Inactivated Vaccine against Vibriosis in Cage-Cultured Asian Seabass, Lates calcarifer, in Malaysia

Vibrio spp. are important aquaculture pathogens that cause vibriosis, affecting large numbers of marine fish species. This study determines the field efficacy of a feed-based inactivated vaccine against vibriosis in cage-cultured Asian seabass. A total of 4800 Asian seabass, kept in a field environment, were separated equally into two groups (vaccinated and non-vaccinated) in duplicate. Fish of Group 1 were orally administered the feed-based vaccine on weeks 0 (prime vaccination), 2 (booster), and 6 (second booster) at 4% body weight, while the non-vaccinated fish of Group 2 were fed with a commercial formulated pellet without the vaccine. Fish gut, mucus, and serum were collected, the length and weight of the fish were noted, while the mortality was recorded at 2-week intervals for a period of 16 weeks. The non-specific lysozyme activities were significantly (p < 0.05) higher in the fish of Group 1 than the non-vaccinated fish of Group 2. Similarly, the specific IgM antibody levels in serum and mucus were significantly (p < 0.05) higher in Group 1 than in Group 2, as seen in the second week, with the highest level 8 weeks after primary immunization. At week 16, the growth performance was significantly (p < 0.05) better in Group 1 and showed lower bacterial isolation in the gut than Group 2. Despite the statistical insignificance (p > 0.05), the survival rate was slightly higher in Group 1 (71.3%) than Group 2 (67.7%). This study revealed that feed-based vaccination improves growth performance, stimulates innate and adaptive immune responses, and increases protection of cultured Asian seabass, L. calcarifer, against vibriosis.

“…Although Asian seabass is considered a relatively hardy species that render them suitable for intensive aquaculture (Rimmer, 2006), infectious disease is arguably the single most important factor responsible for economic loss in fish farming (Hutson, 2014). Streptococcosis (Kayansamruaj et al, 2017; Piamsomboon et al, 2020, 2021) and vibriosis (Chin et al, 2020; Dong et al, 2017; Krupesha Sharma et al, 2012) are among the most common bacterial diseases found in Asian seabass farming. Other pathogenic bacteria include Aeromonas hydrophila , Flavobacterium columnare , Tenacibaculum marinimum and epitheliocystis agents (Chlamydiae) (Hutson, 2014; Rimmer, 2006).…”

Asian seabass (barramundi, giant seaperch, Lates calcarifer) is a popular food fish in Asia and Australia. Native to coastal areas of the Indo-West Pacific, it can now be found from the Persian Gulf to China and northern Australia, either in coastal marine, estuarine, or freshwater habitats (Pethiyagoda & Gill, 2012;Rimmer, 2006). The Asian seabass culture technique was first developed in Thailand during the 1970s (Cheong, 1989;Rimmer, 2006). Since then, Asian seabass farming has been expanded and developed to become an economically important species in the Indo-West Pacific region.In 2020, the global production of Asian seabass from aquaculture was 117,446 tonnes. Almost 40% of this production (45,415 tonnes) was from Thailand (FAO, 2022). In Thailand, Asian seabass culture dominates the coastal aquaculture and it is the third place after tilapia (Oreochromis spp.) and clariid catfish (Clarias spp.) as the most
