Intrinsic and extrinsic factors influencing the timing of arrival of capelin (Mallotus villosus) to spawning grounds in coastal Newfoundland
Bibliographic record
Abstract
Capelin is an important forage fish species in the Northwest Atlantic and the primary prey species of many top predators. Capelin undergo extensive inshore migrations (> 350 km) to coastal spawning grounds in the spring where the timing of inshore arrival is highly variable. I investigated the influence of intrinsic factors and proxies for extrinsic factors on the timing of arrival of capelin at spawning sites on the northeast coast of Newfoundland (2012 and 2013). Despite high inter-annual variation in almost all factors examined, intrinsic factors, specifically length and age, consistently varied with timing of arrival at spawning sites for both males and females, unlike proxies for extrinsic factors. These results are important for the management of this critical fish species, as selective harvesting by the capelin fishery of early-arriving fish may impact the age/size structure of the population, recruitment, and result in increased variability in the timing of spawning.

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.
