Movements of lingcod (<i>Ophiodon elongatus</i>) in southeast Alaska: potential for increased conservation and yield from marine reserves
Bibliographic record
Abstract
Residence time and movement rates of lingcod (Ophiodon elongatus) were recorded in an area closed to fishing in southeast Alaska to evaluate the potential effects of reserves on mortality, egg production, and fishery yield. In 1999, 43 lingcod were tagged with sonic transmitters, and an array of receivers moored in the reserve recorded signals transmitted from tagged fish for 14 months. Most of the tagged fish frequently left the reserve but were only absent for short time periods. Tagged fish showed a high degree of site fidelity. Models generated from the tag data provided a way to predict the effects of marine reserves on yield and eggs per recruit for a cohort of female lingcod. Model results indicated that for lingcod stocks with low abundance, marine reserves could improve egg production while having a small effect on fishery yield. For more abundant stocks, if a portion of the stock is protected in reserves, fishing rates could be increased outside reserves without reducing egg production relative to egg production levels in the absence of reserves.

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.
