The present landscape of both traditional and innovative biotechnology driven vaccines for fish diseases in global aquaculture

The most significant limiting factors in aquaculture, which comprise the majority of the rapidly expanding seafood industry, are infectious diseases of various origins, including viral, bacterial, mycotic, and parasitic infections. As a result, the global aquaculture industry has undergone a significant economic transformation in recent years. The vaccination tactics were also highly effective and affordable, protecting the fish from numerous pathogens, which is crucial for fish culture and societal issues. For over 50 years, researchers have widely recognized fish vaccination as an effective method for preventing many bacterial and viral infections. Vaccination programs enhance the environmental, social, and economic viability of global aquaculture. Science has made significant strides in both fundamental and applied research fields, opening up new paths for creating and improving innovative and efficient vaccines that protect against various infectious diseases. Therefore, recent advancement in vaccines and immunization recommend excellent opportunity to discover new vaccine alternatives these may be effective in combating viruses that cause disease in aquatic creatures. This study highlights the scientific discoveries, current understanding, and prospects for utilizing several vaccines in the aquaculture sector. This review discusses the current generation of vaccinations, including subunit, recombinant, mucosal, synthetic peptide, DNA, vectored, monovalent and polyvalent vaccine and reverse vaccinology. It also discusses the historically inactive and attenuated vaccines. This paper overview to traditional vaccines used in aquaculture and present a comprehensive outline of the more recent approaches and innovative technologies in aquaculture vaccine production.
