Information on Atlantic Salmon (Salmo salar) from Salmon Fishing Area 15 (Gulf New Brunswick) of relevance to the development of a 2nd COSEWIC status report
Bibliographic record
Abstract
This document presents information on Atlantic Salmon (Salmo salar) from Salmon Fishing Area (SFA) 15 (northern New Brunswick in DFO Gulf Region) of relevance to the development of the status report by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). There are 19 rivers with confirmed presence of Atlantic Salmon in this area of which the Restigouche River is the largest river. Data are presented and interpreted relative to the following: biological characteristics, stocking of fish, area of occupancy based on juvenile surveys, indicators of adult abundance from monitored rivers, freshwater production based on juvenile surveys and smolt production, and factors which may be constraining Atlantic Salmon abundance. For the rivers in this area, the indices of adult abundance suggest that there were more Salmon in the mid to late 1980s than there have been in the past 15 years. As a result of changes in fisheries management, spawning escapement has increased from the 1970s and early 1980s resulting in increased abundance of juvenile Salmon. The principal threats in SFA 15 are: habitat alteration including habitat fragmentation due to non-compliant culverts, hydroelectric power generation, disease, unreported poaching and aboriginal catches and, cumulative effect of ecosystem changes.
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.
