Changes in size at age and condition of cod (Gadus morhua) off Labrador and eastern Newfoundland during 1978-2000
Bibliographic record
Abstract
The size-at-age and condition of cod (Gadus morhua) off Labrador and eastern Newfoundland (Northwest Atlantic Fisheries Organization divisions 2J+3KL) were monitored by sampling catches during research bottom-trawl surveys in the offshore during the autumns of 1978-2000. There was considerable spatial, temporal, and individual variability in both size-at-age and condition. Previous investigations have provided evidence that some of the annual variability in these attributes is related to changes in ocean temperature, stock size, and the biomass or availability of prey, notably capelin (Mallotus villosus). However, such explanations are often insufficient because the annual patterns of change varied spatially within the stock. It is shown that inadequacies in sampling, changes in fish distribution, very high apparent mortality and uncertainty regarding trends in prey abundance contribute to difficulty in discerning annual variability in well-being of the cod. Such complications also confound an assessment of the extent to which poor condition might have contributed to the collapse of the stock during the early 1990s.

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.
