Abstract
Video cameras inside underwater housings were used to record the spawning activities of lenok (sharp snout type) in the Uur River, Hovsgol Province (Northern Mongolia). This study constitutes the first underwater video recordings of lenok spawning in the wild. A qualitative description of spawning behavior is presented based on observations taken from five females. Our observations indicate that a previously reported lenok-specific behavior, the presence of satellite females, may have been based on a misidentification of female-mimicking males. Immediately after spawning, lenok females rest before covering their eggs. They share this unusual trait with Hucho taimen, although we cannot determine the pattern of “resting” evolution until we have a more robust phylogeny for the Salmonidae.

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 it
