Effect of baiting gillnets in the Canadian Greenland halibut fishery
Bibliographic record
Abstract
Abstract Catch rates were compared between gillnets with and without bait in the Greenland halibut Reinhardtius hippoglossoides (Walbaum) fishery off Baffin Island, Canada. Two different types of baiting techniques were compared: bait bags where squid were placed into 2‐mm mesh bags, and tied bait where squid were tied into meshes. Both types of baited gillnets significantly increased the capture of the target species, Greenland halibut, with increases of 253.8% and 149.7% for the bait bag and tied bait, respectively. Common bycatch species showed mixed effects, with roughhead grenadier Macrourus berglax Lacépède showing no increase in catch per unit effort (CPUE) for either bait type ( p > 0.05), and porcupine crab Neolithodes grimaldii (Milne‐Edwards and Bouvier) only had a higher CPUE with baited gillnets when bait bags were placed on the footrope. Less common bycatch species—but with threatened populations—showed an increase in CPUE, including Greenland shark Somniosus microcephalus (Bloch and Schneider) and Northern wolffish Anarhichas denticulatus Krøyer. Baiting gillnets affected the CPUE of gillnets in the Greenland halibut fishery, and management should consider how the increased CPUE of both target and bycatch species are affected by this new fishery trend.

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.
