Abstract
In the 19th century approximately 40 fish species (excluding freshwater species) were recorded in the lower Zeeschelde between the Dutch/Belgian border and Antwerpen. In comparison with the 19th century and the first half of the 20th century the total number of fish species in the Beneden-Zeeschelde has decreased considerably. The present checklist (1991-1993) of fishes of the lower Zeeschelde (excluding freshwater species) contains only 26 species. The fish community is composed of marine species (13), catadromous species (3), estaurine residents (9) and one anadromous fish species. Besides, 6 freshwater fis species have presently been recorded. The distribution of diadromous fishes, estaurine residents and freshwater fishes is probably greately affected by low ogygen levels in the lower Zeeschelde, whereas the diasappearence of adventitious marine species is probably also the result of anthropogenic effects on a much wider geographic scale. A comparison was made with recent and historical checklist of fishes of the Westerschelde and the Oosterschelde (the Netherlands).

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
