Abstract

fetched live from OpenAlex

Bivalve feeding models typically attempt to predict clearance rate, the volume of water processed by bivalves, through relationships between organism size and environmental conditions such as temperature, salinity, and particulate matter, which moderate feeding rates (Cranford et al., 2011; Ehrich and Harris, 2015). Despite the importance of accurately quantifying feeding rates in carrying capacity estimations, feeding models are often not validated with empirical data. This report tests and validates selected literature-based clearance rate models for cultured eastern oysters (Crassostrea virginica) using data collected in over the growing season in the Damariscotta River Estuary (DRE) as well as in cold water laboratory experiments in Atlantic Canada.

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
