Abstract
distributed along the western Atlantic Ocean from the Gulf of St. Lawrence to Florida. It is also referred to as “Bay Quahaug”, “Hard Clam”, “Cherrystone”, and “Littleneck”. Because of similarities in appearance this species is sometimes confused wih surf clams. The larger beds in Atlantic Canada occur in waters adjacent to the Gulf of St. Lawrence with a few smaller beds occurring along the coast of mainland Nova Scotia and in St. Mary’s Bay. Mercenaria has a thick shell with a shiny purple color on the inside edge of the anterior end. This portion of the shell was used in the past by native peoples as “wampum ” which may account for the name Mercenaria. This species is found from intertidal to subtidal depths of 15 meters in sandy, silty and mud bottoms, primarily in estuaries where the salinity is somewhat lower than open ocean levels. Quahaugs are shallow burrowers and are found in the sediment at depths of 5-10 centimeters. Sexes are separate and spawning occurs from late spring to early summer depending on temperature. Eggs and sperm are released through excurrent siphons. Fertilization occurs externally and larval development is typical of bivalves. Juveniles are typically males which in later years may change sex and spawn as females. Sizes reach 5-10 centimeters. The scarcity of large beds in the Bay of Fundy and Scotian Shelf discourages interest in commercial harvesting. Some commercial harvesting occurs in P.E.I. and along Northumberland Strait. Size limits and daily quotas differ between locations. It is one of the most valuable shellfish species harvested in the United

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.
