Controlled Field Trial of Pancreas Disease Vaccines in Farmed Atlantic Salmon: Effects on Growth and Mortality During a SAV2 Outbreak.

ABSTRACT: Pancreas disease (PD), caused by salmonid alphavirus (SAV), is a concern for salmon aquaculture in Scotland, Ireland and Norway. This article presents results from a controlled field trial monitoring three study groups from vaccination to harvest. The groups represented a subset of the total fish population within a single sea cage, reared under commercial farming conditions. The trial aimed to evaluate the effects of two licensed PD vaccines in Norway-ALPHA JECT micro 1 PD (AJm1PD) and Clynav-on growth and mortality during a PD outbreak, relative to an unvaccinated control group. Clinical PD, caused by SAV subtype 2, was confirmed in June 2024, approximately 14 months after sea transfer and 2 months before harvest. At harvest, both vaccinated groups exhibited significantly higher weights
