Science response: 4RST Greenland halibut precautionary approach
Bibliographic record
Abstract
Since 2006, Canada has made national and international commitments to apply the precautionary approach (PA) in fisheries decision-making (DFO 2006). In recent years, Canada has taken several initiatives to define and establish benchmarks under the precautionary approach in the context of fisheries and incorporate them into fisheries management. Following recommendations made by the Commissioner of the Environment and Sustainable Development (CESD 2016), Fisheries and Oceans Canada (DFO) committed to developing and implementing a precautionary approach for the sustainable management of Greenland halibut (Reinhardtius hippoglossoides) in the Gulf of St. Lawrence (GSL, Northwest Atlantic Fisheries Organization [NAFO] Divisions 4RST). Greenland halibut in the GSL is a stock for which a precautionary approach is under development. A stock status indicator and limit reference point have been established since February 2017 (DFO 2018). A working group, comprised of representatives from DFO (Science and Fisheries Management), the industry, the provincial governments of Quebec and Newfoundland and Labrador, and Aboriginal groups, was created in the fall of 2018 to develop a precautionary approach proposal. Objectives relating to the management of this stock, a target reference and upper stock reference points have been agreed on by the working group in 2020 (DFO 2021). The working group also considered the development of decision rules (hereinafter referred to as harvest control rules; HCR) and developed three HCR proposals. The Resource Management, Aquaculture and Aboriginal Affairs Directorate (hereafter referred to as Fisheries Management) has requested a Science Advice from the Regional Science Branch to determine the compliance of the proposed HCR according to the principles of the precautionary approach and to compare their advantages and disadvantages. This Science Response stems from the Regional Science Response process of November 15, 2021 on the Development of the Gulf of St. Lawrence Greenland Halibut Precautionary Approach (4RST).

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.
