Abstract
This study, based on field and laboratory observations, investigated the role of parasites as the cause of disease outbreaks and mass mortality in wild and cultured fish in Newfoundland over three decades. One ciliated protozoan, Trichodina jadranica (Ciliophora), and Loma branchialis (Microspora) were responsible for mass mortality of cultured fry and fingerling Atlantic cod (Gadus morhua) while a myxozoan, Tetracapsuloides bryosalmonae, and plerocercoids of a cestode, Diphyllobothrium dendriticum, caused a die-off of hatchery-reared Arctic charr (Salvelinus alpinus) and rainbow trout (Oncorhynchus mykiss) respectively after transfer to outdoor cages. A hematophagous copepod, Lernaeocera branchialis, was associated with mortality of wild Atlantic cod both in the laboratory and possibly in the field. One additional parasite, a coccidian, Goussia caseosa, caused lesions in the swim bladder of the roughhead grenadier, Macrourus berglax, a deep-sea fish. It is surmised that parasites have played a major role in mortality of both wild and cultured fish in New-foundland. Recommendations are made to prevent potential die-offs in cultured fish.

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.
