2.4. Control and prevention
2.4.1. Vaccination
Effective formalin-killed commercial vaccines for RSIVD are currently available for red sea bream, striped
jack and other fish species belonging to the genus Seriola in Japan. Protection of fish belonging to the
genus Oplegnathus by vaccination is difficult.
2.4.2. Chemotherapy
Not available.
2.4.3. Immunostimulation
Under investigation.
2.4.4. Resistance breeding
Under investigation.
2.4.5. Restocking with resistant species
Under investigation.
2.4.6. Blocking agents
Unknown.
2.4.7. Disinfection of eggs and larvae
No data available.
2.4.8. General husbandry practices
A number of general husbandry practices are used to reduce RSIVD-associated losses. These include:
introducing pathogen-free fish; implementing hygiene practices on farms; and avoiding practices that can
decrease water quality and/or increase stress, such as overcrowding and overfeeding.
