Vaccination plays an important role in large-scale commercial fish farming and has been a key reason for the success of salmon cultivation. In addition to salmon and trout, commercial vaccines are available for channel catfish, European seabass and seabream, Japanese amberjack and yellowtail, tilapia and Atlantic cod. In general, empirically developed vaccines based on inactivated bacterial pathogens have proven to be very efficacious in fish. Fewer commercially available viral vaccines and no parasite vaccines exist. Substantial efficacy data are available for new fish vaccines and advanced technology has been implemented. However, before such vaccines can be successfully commercialized, several hurdles have to be overcome regarding the production of cheap but effective antigens and adjuvants, while bearing in mind environmental and associated regulatory concerns (e.g., those that limit the use of live vaccines). Pharmaceutical companies have performed a considerable amount of research on fish vaccines, however, limited information is available in scientific publications. In addition, salmonids dominate both the literature and commercial focus, despite their relatively small contribution to the total volume of farmed fish in the world. This review provides an overview of the fish vaccines that are currently commercially available and some viewpoints on how the field is likely to evolve in the near future.

Infectious hematopoietic necrosis virus (IHNV) is a serious pathogen in the salmonid aquaculture industry and leads to economic losses in the world. This study aimed to develop a new oral DNA vaccine designed to protect rainbow trout against infection by IHNV. Fish were administered via the oral route by the attenuated Salmonella enterica serovar Typhimurium as a carrier of pcDNA3.

Single-cycle viruses hold great promise as fish viral vaccines due to their high protective efficacy. Although the efficacy of the vaccine in olive flounder and rainbow trout has been proven through previous research, safety must be additionally proven considering the environment of use for commercialization. This study comprehensively assesses the safety of rVHSV-GΔTM and its impact on both the host and the surrounding environment, including the coastal habitat of nearby species and seawater.

Vibrio harveyi is a common sort of pathogenic bacterium in marine, which annually gives rise to huge financial losses in aquaculture industry. Flagellin is one of the important virulence factors for bacteria, but meanwhile it is also a preferable vaccine candidate. In this study, we have identified and analyzed two flagellin antigens of V.

Background: Vaccination of farmed salmonids has been an integral part of preventing infectious diseases in Norway's aquaculture industry. In Norway, vaccine usage is regulated by the government. There is a need to monitor vaccine usage for both regulatory and research purposes, at local and national scales.
