Abstract
Atlantic salmon with amoebic gill disease (AGD) were treated with chloramine-T to compare its effectiveness with that of freshwater bathing. In 250-L tank trials, treatment of seawater with chloramine-T reduced amoeba density on the gills to levels significantly lower than when treated with seawater alone. There was no further change in amoeba levels in fish bathed for 3 or 6 h compared with 1 h of treatment. Plasma lactate levels in fish bathed in chloramine-T for 6 h showed no differences across treatments. In 1000-L tank trials using freshwater alone or seawater with chloramine-T, significant reductions in amoeba density occurred compared with pre-bath levels. Histological analysis of gill tissue revealed AGD lesion levels to increase, then to return to pre-bath levels within 1 week for freshwater-treated fish, while chloramine-T- and seawater-treated fish had higher levels of AGD lesions from 2 weeks post bathing. Immunodot-blot data indicated an initial significant increase in prevalence of lesions in seawater and chloramine-T-treated fish, which declined to levels significantly lower than pre-bath levels by 3 weeks post bathing, compared with the freshwater-treated fish, which had significantly lower levels than controls by 2 weeks post bathing. At reducing amoeba density, it is apparent that bathing AGD-affected Atlantic salmon in seawater with chloramine-T proved at least as effective as freshwater.

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 it
