Parasites from ‘Alien Shores’: The Decline of Canada's Freshwater Fishing Industry
Bibliographic record
Abstract
Abstract: After 1900, the Northwest fishing industry expanded substantially from southern Manitoba to the Northwest Territories, with production directed principally to American urban markets. In response to the economic crisis of the 1930s, new international trade regulations prohibited the importation of fish infected with the Triaenophorus parasite and included two of the most important commercial freshwater fish species: tullibee and lake whitefish. In the following decades, in spite of repeated state and scientific interventions in the fishery, Canada's freshwater fishing industry was unable to fully recover from the economic impacts of the new trade regulations. This failure reflected the unprecedented influence of the parasite and its ecological relationships to other species and the freshwaters in which it was found. This paper goes beyond a conventional narrative of the impacts of economic protectionism to ascertain how the natural context in which resources such as fish are found intervenes in human socio-economic affairs.

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.
