Apparent migration and natal homing of a small minnow in a large ancient lake
Bibliographic record
Abstract
Migratory freshwater fish species are particularly susceptible to population decline because they rely on multiple habitats and open passages to complete their life cycle. Understanding the migratory patterns of cyprinids is thus essential for their management and conservation. Gnathopogon caerelescens, a small cyprinid species endemic to Lake Biwa (Japan), is one of the most important targets of inland fisheries. However, their abundance has dramatically decreased. By using an extensive alizarin complexone-mark-and-recapture program for of G. caerelescens juveniles, together with the collaboration of commercial fishermen, this cyprinid fish was demonstrated as: (1) migrating from a nursery lagoon toward the main lake and moving along the near-shore from spring to autumn; (2) migrating from the near-shore shallow habitats to off-shore deep habitats from autumn to winter; and (3) migrating to a nursery lagoon from off-shore deep habitats from winter to spring. These results highlighted the importance of protecting individual spawning/nursery habitats, and maintaining connectivity between each spawning/nursery habitat and the lake system.

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.
