Abstract

fetched live from OpenAlex

An exploratory Atlantic hagfish (Myxine glutinosa) survey was conducted on the southwest slope of the Newfoundland Grand Bank during autumn 2002 to collect samples for a biological resource assessment and investigate the selective properties of baited 227-litre traps with 12.7, 13.5, and 14.3 mm (1/2", 17/32", and 9/16") diameter escape holes. Atlantic hagfish were found to exhibit a juvenile hermaphroditic stage. Female Atlantic hagfish exhibited a total length (TL) at first, 50%, and 100 % sexual maturity of 354, 378, and 440 mm, respectively. The testis was small and rudimen-tary showing no sign of maturation in the form of enlarged lobules in 350 hagfish examined within a size range of 195–638 mm TL. Each sexually mature female possessed a single clutch of developing ovoid eggs of similar size and 28 % possessed both developing and degenerating eggs. Degenerating eggs were limited to the early stage of the reproductive cycle among females with developing eggs that were <12 mm in length. Examination of females with large (≥14 mm) eggs revealed a positive correlation (r2 = 0.61) between fecundity and total body length, however, the reproductive potential was low (11–38 eggs per female). Recent evidence of a seasonal reproductive cycle and current findings of a bimodal egg length-frequency distribution and the presence of several females with

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.
