Do salmon lice, <i>Lepeophtheirus salmonis</i>, have a role in the epidemiology of amoebic gill disease caused by <i>Neoparamoeba perurans</i>?
Bibliographic record
Abstract
Amoebic gill disease (AGD) is an acute to chronic proliferative condition of farmed Atlantic salmon caused by Neoparamoeba perurans (see Young, Crosbie, Adams, Nowak & Morrison 2007; Young, Dykova ´, Snekvik, Nowak & Morrison 2008a).AGD and N. perurans have been reported in most salmon-producing countries except Canada.In western North America, AGD occurs in Washington State but not in the adjacent British Columbia (B.C.).Despite the ubiquitous distribution of the disease and its causative agent, reservoir populations of the amoeba and the mechanism(s) of transmission to and among farmed fish have not been elucidated.The purpose of this study was to conduct a preliminary survey for reservoirs of N. perurans at or adjacent to salmon populations suspected to be affected with AGD.Forty Atlantic salmon, Salmo salar, were sampled in September 2008 -twenty from a farm in Puget Sound, Washington State that historically has been affected by AGD (Kent, Sawyer & Hedrick 1988;Douglas-Helders, Saksida, Raverty & Nowak 2001; Young, Dykova ´, Nowak & Morrison 2008b) and twenty from a farm near Campbell River on

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
