Myctophid (Myctophidae) Abundance and Ecology in the Gulf of Alaska in Winter
Bibliographic record
Abstract
The distribution and abundance of four common myctophid fish species in the upper epipelagic layer of the northeastern North Pacific in winter were analyzed based on results of the research surveys in the Gulf of Alaska in 2019 and 2020. The myctophid community in the considered layer was dominated in number by blue lanternfish, Tarletonbeania crenularis. The blue lanternfish-driven myctophid community likely occupies the whole eastern part of the Subarctic Front from the longitude 150° W to the Canadian exclusive economic zone (EEZ). The abundance and biomass estimates for four common myctophid species in the northeastern and northwestern North Pacific Ocean were generally comparable. The largest percentage of northern lampfish (Stenobrachius leucopsarus) in winter catches was represented by small juveniles. It is likely that these small juveniles are intensively transported by the Subarctic Current and then concentrate in the Bering Sea. The pattern of daily vertical migrations of common myctophid species is discussed. The new observations confirm general understandings on the functional role of common myctophid species in marine communities.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
