DFO Quebec Region Biodiversity of the snow crab trawl survey in the St. Lawrence Estuary (2019)
Bibliographic record
Abstract
A research survey on snow crab (Chionoecetes opilio), using a beam trawl, was carried out by DFO in 2019 in the St. Lawrence Lower Estuary between Forestville, Baie-Comeau and Matane. The main objective of this survey was to assess crab abundance and the diversity of benthic species associated with the crab habitat according to a fixed station sampling plan. The data provided is a compilation by species (or taxon), by station. The taxonomic and geographic validity of the records were verified. Un relevé de recherche sur le crabe des neiges (Chionoecetes opilio), à l'aide d'un chalut à perche (connu aussi sous le nom de chalut à bâton), a été réalisé par le MPO en 2019 dans l’estuaire maritime du Saint-Laurent entre Forestville, Baie-Comeau et Matane. L’objectif principal de ce relevé était d’évaluer l’abondance du crabe et la diversité des espèces benthiques associées à l’habitat du crabe selon un plan d'échantillonnage à stations fixes. Les données fournies sont une compilation par espèce (ou taxon), par station. La validité taxonomique et géographique des enregistrements a été vérifiée.

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.
