Vaccination Programs

Similar to terrestrial animals, misuse of antibiotics to control these infectious diseases could lead to the generation of antimicrobial resistance (AMR). Fishes may ingest different doses of the antibiotic, which in excess, accumulate in the fish tissue. Organisms in fish tissues under antibiotic stress would be promoted to produce antibiotic resistance genes (ARGs). These would eventually be released to the local aquatic system and facilitated to contaminate nearby farms. Combined with proper farm management through good hygiene and limited stress, vaccination is an important key to combat infectious diseases and reducing AMR generation.

Although part of the global aquaculture, molluscs and aquatic plants do not possess advanced immune system for vaccines to be effective.

An aquatic veterinarian or fish health specialist/professional should be consulted to determine the appropriate licensed vaccines to use and also when developing autogenous vaccines for specific pathogen and fish farm.

Aquaculture vaccination is usually administered in small juveniles/larvae and revaccination may be needed depending on possible outbreaks on nearby areas and the long-term protection of vaccines.

In addition to hygiene and stress, species variety and temperature also affects the effectiveness of the vaccine administered. Some species differ eliciting immune response effective for a given fish pathogen. Seabass, including barramundi, acclimated to warm temperatures have detectable antibodies after one week of immunization
