Abstract

fetched live from OpenAlex

A survey of the shallows around Sable Island on the Scotian Shelf in July-August 1982 confirmed the summer concentrations of juvenile haddock, Melanogrammus aeglefinus, which were evidence from a survey in August 1981. Comparison of the spatial distributions of juveniles showed some persistence of concentration of O-group fish, but not of 1-group fish, both during two successive surveys in 1982 and from surveys in 1981 and 1982. Two 24-hr fishing experiments showed well-defined diel vertical migration in O-group but not in 1-group haddock. Estimates of population size indicate reductions of about 46 % for O-group and 39% for 1-group fish from 1981 to 1982. The results from such surveys may be indicative of recruitment to the haddock stock on the central part of the Scotian Shelf.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
