Vaccination against Furunculosis in Arctic Char: Efficacy of a Commercial Vaccine
Bibliographic record
Abstract
Arctic char Salvelinus alpinus are susceptible to furunculosis, a serious bacterial disease that affects the productivity of salmonid farms around the world. The objective of this laboratory study was to evaluate the efficacy of a commercially available vaccine against furunculosis in two strains of Arctic char. Labrador and Nauyuk char were injected with Aqua Health Furogen 2 or 0.9% NaCl. At 87 and 108 d postvaccination, fish were challenged with Aeromonas salmonicida by immersion. In both challenges, the Aqua Health vaccine provided significant protection against furunculosis; percent cumulative mortality was significantly (P = 0.005) greater for the fish vaccinated with 0.9% NaCl than for those vaccinated with Furogen 2. Strain (P = 0.30), days since vaccination (P = 0.38), and the interaction between vaccine and strain (P = 0.40) were not significant. The point estimate for the preventive fraction (PF) was greater than 0.90 for the Labrador fish vaccinated with Furogen 2; for the Nauyuk fish, the PF was 0.89 and 0.38 at 87 and 108 d, respectively. Relative proportion survival values were also estimated and were usually similar to, but always lower than, the PF estimates.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
