Physiological Responses of Walleyes to Live-Release Angling Tournaments
Bibliographic record
Abstract
Abstract This study examines the physiological impacts of live-release angling tournament practices on walleyes Sander vitreus (formerly Stizostedion vitreum). Blood and white muscle samples were taken from walleyes following the weigh-in at several live-release angling tournaments in southern Ontario. The tournament walleyes had significantly elevated plasma cortisol levels in comparison with those of the control walleyes, indicating that tournament practices elicit a significant stress response in the tournament fish. Increased creatine phosphokinase and lactate dehydrogenase activities revealed that walleyes experience a moderate degree of cellular damage during live-release angling tournaments. In contrast to recent research with largemouth bass Micropterus salmoides, the tournament walleyes showed evidence of plasma ion loss. The tournament walleyes also experienced dramatic reductions in white muscle energy stores (phosphocreatine, ATP, and glycogen) and corresponding increases in plasma and white muscle lactate levels when compared with those of the control fish. These metabolic changes were similar in magnitude to the changes previously observed in largemouth bass following tournaments and suggest that current tournament procedures may commonly cause relatively large bouts of anaerobic metabolism in fish.

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.
