Physiological status of coho salmon (<i>Oncorhynchus kisutch</i>) captured in commercial nonretention fisheries
Bibliographic record
Abstract
The physical, hematological, and metabolic condition of 303 adult coho salmon (Oncorhynchus kisutch )w as examined following capture with three commercial fishing gear types (seine, troll, and gill net) and a variety of meth - ods. All fish arrived onboard in a state of severe metabolic exhaustion, and physiological differences among gear types and fishing methods were few and relatively small. Fish showed less physiological disruption with a brailing versus a ramping method of seine fishing and with a 30-min versus a 60-min net soak time for gillnet fishing. The visual rat- ings of physical condition (nonbleeding, vigorous, and lethargic) correlated significantly with hematocrit, plasma osmolality, plasma lactate, and plasma sodium. Fish placed in recovery boxes for 30-60 min onboard fishing vessels did not show the expected metabolic recovery; only plasma potassium recovered significantly. However, plasma lactate levels declined significantly for 125 fish placed in a net pen for 24 h, suggesting that metabolic recovery was possible after commercial capture. Because of a concern that the current recovery box design does not effect optimum recovery, we recommend that future experiments test a better-designed recovery box that orients fish into flowing water. Resume : Nous avons examine la condition physique, hematologique et metabolique de 303 cohos (Oncorhynchus kisutch) adultes apres leur capture dans trois types d'engins de peche commerciale (senne, lignes et filet maillant). Tous les poissons arrivaient a bord dans un etat de grave epuisement metabolique, et les differences physiologiques etaient peu nombreuses et relativement faibles d'un type d'engin et d'une methode de peche a l'autre. Les poissons presen- taient moins de perturbations physiologiques dans le cas du salabardage qu'avec le hissage sur la rampe dans la peche a la senne, et avec un temps de mouillage de 30 min qu'avec 60 min dans la peche aux filets maillants. Les evalua- tions visuelles de la condition physique (absence de saignement, poisson vigoureux ou lethargique) etaient significative- ment correlees a l'hematocrite, a l'osmolalite plasmique et aux concentrations de lactate et de sodium dans le plasma. Les poissons places dans des viviers de recuperation pendant 30-60 min a bord des bateaux de peche se presentaient pas le retablissement metabolique prevu, car seul le potassium plasmique remontait de facon notable. Toutefois, les concentrations plasmiques de lactate baissaient de facon significative chez 125 poissons places dans un parc de filet pendant 24 h, ce qui permet de penser que la recuperation metabolique est possible apres la capture commerciale. Il semble que la conception actuelle des viviers de recuperation ne soit pas optimale, aussi recommandons-nous que des experiences futures mettent a l'essai un vivier mieux concu qui oriente les poissons dans un courant d'eau.

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.
