Abstract
This work assesses the international trade in the Unionidae species from 1987 to 2015. The species of the Unionidae family are listed in the CITES International Convention. Most of them (26 species from 12 genera) are included in Appendix I of CITES, only three species (Cyprogenia aberti, Pleurobema clava and Epioblasma torulosa rangiana) are listed in Annex II. They are mainly US endemic, or USA and Canada. Most of them occur only in one or two rivers, often only in a certain section of the river. These species are host specific. Some of them are bound to only one genus or species of fish. From a trading point of view, Unionidae were traded in the following forms: shells, carved shells, derivatives, live individuals and specimens. The species Dromus dromas, Pleurobema clava, Cyprogenia aberti and Conradilla caelata were traded the most. The most common was the trade in the shells of individuals whose origin dates from before the inclusion of the species Unionidae to CITES for commercial purposes. These individuals were mostly of an unknown provenance and if the country of origin was stated, it was United States of America. The places, from which they were exported most were Hongong and the Philippines. The most frequent place of import were the US.

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.
