Stock Annex: Blue ling (Molva dypterygia) in Subareas 1, 2, 4 and Division 3.a
Bibliographic record
Abstract
In the Northeast Atlantic, blue ling (Molva dypterygia) is distributed from the Barents Sea along the coast of Norway to the west of the British Isles, around the Faroe Islands and Iceland and off the east coast of Greenland. ICES now works with three different stocks for this area (Figure 1):· bli.27.5a14, blue ling (Molva dypterygia) in Icelandic and Greenland waters· bli.27.5b6712, blue ling (Molva dypterygia) in Celtic Seas, Faroes grounds, Rockall, Hatton Banks and Mid-Atlantic Ridge· bli.27.123a4, blue ling (Molva dypterygia) in Northeast Arctic, North Sea, Skagerrak and Kattegat Biological investigations in the early 1980s suggested that at least two adult stock components were found within the area, a northern stock in Subarea 14 and Division 5.a with a small component in 5.b, and a southern stock in Subarea 6 and adjacent waters in Division 5.b. However, the observations of spawning aggregations in each of these areas and elsewhere suggest further stock separations. This is supported by differences in length and age structures between areas as well as in growth and maturity. Eggs and larval data from early studies also suggest the existence of many spawning grounds.This stock annex is for bli.27.123a4 and this stock area was defined after a revision of bli.27.nea in WGDEEP 2024. See detailed description of this process in WGDEEP report, section 4.1 Stock description and management units.New genetic information (McGill et al 2023) clearly separates the eastern, Norwegian areas (subareas1-4) from the western areas (Atlantic basin: Greenland, Rockall, Atlantic slope). This information was the background for separating subarea 12 from the eastern areas (and include this subarea to bli.27.5b67).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
