Use vaccinations Sustainable Aquaculture

In 2011, a replicated, controlled study in Tasmania, Australia (Costa et al., 2011) found increased survival rates in salmon, Salmo salar, vaccinated (using Yersinivac-B) and then exposed to the disease-causing bacteria, Yersinia ruckeri. Vaccinated salmon showed higher rates of survival than the unvaccinated control group. A trypsinated version of the Yersinivac-B vaccine produced higher survival rates than an untrypsinated vaccine (65% and 52% survival respectively). Y. Ruckeri causes yersiniosis. Groups of salmon were given one of two vaccinations; either Yersinivac-B or a trypsinated version of Yersinivac-B.  A control group received no vaccination. Six weeks after vaccination, salmon from each treatment were exposed to Y.ruckeri and mortality levels were monitored for 14 days.
