The effect of vaccine‐associated cross‐stitch vertebrae pathology on growth of farmed Atlantic salmon
Abstract A field study comparing two vaccine regimes against pancreas disease (PD) was carried out in 2018 S0 year class smolts at two commercial sea cage sites in southern Norway. The fish from the same hatchery source were immunized using licensed vaccines; either a DNA PD vaccine and a hexavalent...
