Spring inventory of a multispecies spawning ground: ichthyofauna Gatineau River Rapids, Quebec
Bibliographic record
Abstract
A spring survey of fishes was conducted in the Gatineau River (Quebec), in the first rapids upstream of its confluence with the Ottawa River, to establish the fish spawning chronosequence, especially for the three species of redhorses. The sampling resulted in the capture of 2388 fish belonging to 13 families and 39 species. Six of these species have been assessed by COSEWIC. Sixteen species were in spawning readiness. Spawning of the Silver Redhorse and Shorthead Redhorse occurred first, followed by the River Redhorse. Stage V males of the three redhorse species were captured earlier and in greater numbers than females. These observations are consistent with other studies which suggest that males precede females to the spawning grounds, that females remain there for a short period and that a minimum two males per female is required for reproduction. This study shows that the Gatineau River rapids must be protected because they harbor three species that have obtained a status by COSEWIC (Threatened: Channel Darter; Special concern: Northern Brook Lamprey and River Redhorse) as well as being an important multi-species spawning ground.

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.
