Information on Atlantic Salmon (Salmo salar) from Salmon Fishing Area 18 (Gulf Nova Scotia) of relevance to the development of a 2nd COSEWIC status report
Bibliographic record
Abstract
This document presents information on Atlantic Salmon (Salmo salar) for rivers in Salmon Fishing Area 18 (SFA 18; Northumberland Strait Nova Scotia and Western Cape Breton) of relevance to the development of the status report by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). There are 55 potential Atlantic Salmon rivers in SFA 18. Of these, the Gulf Nova Scotia (GNS) program focuses its monitoring efforts on four index rivers within SFA 18: The Margaree River, West River Antigonish, East River Pictou, and River Philip. For the Margaree River in 2019, the estimated eggs in the returns of small Salmon and large Salmon combined were 3.9 times greater than the lower reference point (LRP) value. The Salmon population has remained above the LRP for the duration of the Margaree monitoring program (1987 to present). However, returns to all rivers in SFA 18 remain below the long-term return average. The principal threats in SFA 18 are: habitat shifting and alteration, extreme temperatures, and droughts, all of which are related to global climate change.
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.
