Abstract

fetched live from OpenAlex

Freshwater fisheries face diverse, interacting stressors that threaten freshwater fish populations and global freshwater biodiversity. In Canada, freshwater fisheries are managed and conserved by various government agencies and departments (lead actors) and a supporting cast of non-governmental groups and individuals (supporting actors) whose efforts range from coordinated and synergistic to disjunct and antagonistic. This is problematic, because threats to freshwater fisheries and biodiversity are highly synergistic. In some cases, these threats are addressed by strong, combined efforts by lead and supporting actors. Here, greater capacity and resilience are achieved via a composite approach, meaning an effective combination of parts to create one whole. In other cases, efforts are less plural and/or combined, and therefore weaker. We use insights from an expert sample of freshwater fisheries practitioners to describe the supporting cast, how it varies from a critical asset to an untapped resource, and the determinants of these different outcomes. Our results are not only applicable to Canada and/or freshwater fisheries, but to other cases where environmental management and conservation involve both lead and supporting actors.

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.
