Abstract

fetched live from OpenAlex

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.

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.
