Distribution and Monitoring of Pink Salmon (Oncorhynchus gorbuscha) in British Columbia, Canada – a contribution to the development of a Pink Salmon Watch
Bibliographic record
Abstract
This report provides an inventory of pink salmon in British Columbia (BC), Canada and examines past efforts to monitor the spawning escapement of these salmon. The report is based on recent work conducted for the Pacific Fisheries Resource Conservation Council to provide reference material on the distribution and monitoring of Pacific salmonids in BC and the Yukon Territory. The escapement data has been collected since the early 1950s by the Canadian Department of Fisheries and Oceans, and for pink salmon in the Fraser River by the Pacific Salmon Commission (all data are contained in a Microsoft Access database). Pink salmon in British Columbia utilize rivers and streams from the Taku River in northern BC south to the Fraser River. Production in the even and odd-year lines of pinks do not necessarily have equal distributions or population sizes. The extreme example is the absence of Fraser River pink salmon in the even years. Similarly, pink salmon along the west coasts of Vancouver Island and the Queen Charlotte Islands have much smaller pink returns in the odd years than in the even years. However, overall, there are hundreds of pink populations that may be included in a subarctic Pacific monitoring program, and there have been extensive efforts to monitor these returns for approximately 50 years. These monitoring efforts do vary by geographic area and time periods, and very few are monitored in a quantitative manner. This report may be used as a reference for similar reports from other countries but does not presume to recommend a monitoring design. It does discussion sources of variation that should be considered and the need for a common objective as a basis for a monitoring program. Before extensive effort to assess and document this variation is undertaken, there is a need to set objectives and desired levels of precision. Once a comprehensive inventory of pink salmon populations is produced, it is anticipated that the inventory of monitored streams will be up-dated each year. Ultimately, a database will be available to study the impact of climate on one of the key indicator species in the subarctic Pacific. NPAFC Docu 707 October 2003

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.
