Review of the status of the Northern Abalone, Haliotis kamtschatkana, in Canada
Bibliographic record
Abstract
The Northern Abalone (Haliotis kamtschatkana) is the only abalone species in Canada and is widely distributed along the entire outer coast of British Columbia.In the late 1970s and 1980, there was a commercial fishery, but following a peak in landings in [1978][1979], landings rapidly declined.Its distribution in commercially exploitable concentrations is patchy, making stock assessments difficult to conduct.However, in the late 1980s, consistently low estimated abundance levels and increasing evidence for a substantial illegal harvest of abalone raised conservation concerns, resulting in aboriginal, recreational and commercial fisheries closures in 1990.Studies in other abalone species suggest that abalone larvae disperse over relatively short distances.If true for Northern Abalone as well, then this species may be particularly vulnerable to localised extirpations.Through the 1990s, there was no evidence of significant Northern Abalone recruitment along Canada's Pacific coast, and because of a high price, abalone poaching is still occurring.Expansion in the range of Sea Otters (Enhydra lutris), a major abalone predator, is also increasing natural mortality.Given these circumstances, a COSEWIC status of "threatened" was recommended.

How this classification was reachedexpand
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.
