A preliminary investigation of winter daily food intake by four small teleost fish species from the Igoda Estuary, Eastern Cape, South Africa
Bibliographic record
Abstract
The winter diet and daily ration of four small size classes of estuary-associated fishes, Rhabdosargus holubi, Gilchristella aestuaria, Glossogobius callidus and Monodactylus falciformis, from the temporarily open/closed Igoda Estuary were investigated. The diet of G. callidus was dominated by gammarid amphipods and copepods. Copepods accounted for 70% by volume of the stomach contents of M. falciformis and 50% in G. aestuaria. Plant material and copepods were the most prominent food items in the stomach contents of R. holubi. All species except G. aestuaria showed a diel pattern in feeding activity. Gut evacuation rates ranged between 0.3 and 2.5 h–1 for incubations, and from 0.1–0.4 h–1 in situ. Daily ingestion rates, estimated using an in situ stomach content analysis technique, ranged between 4.0% and 10.2% body dry mass.

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.
