1992 were treated with oxolinic acid and a bacterin. The bacterin was developed against furun-culosis and enteric redmouth disease. Among the 2,552 fish that were treated since 1986, 362 died and 65 (18%) of those fish had furunculosis. Among 206 untreated fish that were maintained as controls, 109 died and 63 (57.8%) had furunculosis. The reduction in mortality could not be attributed to either vaccine or antibiotic alone without further study. A 3-year study was designed to investigate if adult Atlantic salmon, undergoing the stress of migration, handling, and spawning, could mount a protective humoral immune response. Although the salmon were able to produce an agglutinin response, evidence was not found for production of a protective humoral response by these vaccinated Atlantic salmon. The infectious bacterial disease furunculosis (causative agent, Aeromonas salmonicida), causes losses among sea-run Atlantic salmon Salmo salar that are captured from the Merrimack and Con-necticut rivers and held for spawning. Enteric red-mouth disease (ERM), caused by Yersinia ruckeri
