Abstract

fetched live from OpenAlex

The report is based on observations of food composition in stomachs of common predatory fish species caught during recreational fisheries in the Fraser River basin, in particular Lake Morris (British Columbia, Canada), as cutthroat Oncorhynchus clarkii, mountain whitefish Prosopium williamsoni, and northern pikeminnow Ptychocheilus oregonensis. Up to 164, 126 and 28 fry of pink salmon Oncorhynchus gorbuscha were found in the stomachs of the listed fish species, respectively, during pink salmon downstream migration in April — early May. In this season, these species can consume a significant portion of their annual food ration, especially in energy terms. In the lake under con- sideration, these three predators are capable to eliminate pink salmon fry from the spawning of about 2,390 pink salmon in a small inflowing stream. Since the spawners of only the odd-years broodline of pink salmon reproduce in the rivers of the southern Pacific coast of Canada, the migration of their juveniles creates a significant difference in feeding conditions for predatory fish in adjacent years.

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.

Not 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.
