Abstract

fetched live from OpenAlex

such as size-at-age and size-at-maturity, as essential inputs (Maunder and Punt, 2013), while multiple data-limited assessment approaches estimate fshing mortality from changes in the length distribution (Chong et al., 2020).Further, assessing progress relative to management regulations often requires the ability to accurately convert among length measurements, such as precaudal, standard, fork, natural total, and stretched total lengths, due to inconsistencies in the types of standard measurements collected among various research programs (Francis, 2006).For example, straight-line fork length (FL SL ), which is measured as the straight-line distance from the tip of the snout to the fork of the tail, is the measurement type designated for shark regulations in the Atlantic Ocean by both the International Commission for the Conservation of Atlantic Tunas (ICCAT) and by NOAA's National Marine Fisheries Service Highly Migratory Species Division 1 (ICCAT, 2016).However, particularly for large fsh, many researchers and fshermen use over-the-body (OTB; synonymous with curved measurements for this paper) measurements in which a measuring tape is laid along the surface 1 https://media.f isheries.noaa.

Not 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.
