Life+ Alosa alosa Irstea report 3: Actions C1 - D7\nJuly 2013-June 2014
Bibliographic record
Abstract
This report presents works managed by Irstea, Aquarium La Rochelle and Borea Team concerning the set up of an ex situ rearing method for juveniles Allis shads Alosa alosa, and the monitoring of sexual maturation. Because of biomass increase a second biological filter has been installed in April 2014. Mortality was higher during this period because of bacterial and kidney diseases. Histological analysis of samples collected in June 2013 showed a normal gonadal development. A third set of samplings for the monitoring of sexual maturation was carried out in June 2014. / Ce rapport présente les travaux conduits par Irstea, l'Aquarium de La Rochelle et l'équipe Borea dans le cadre de la mise au point d'une méthode d'élevage ex situ de juvéniles de grande alose Alosa alosa et du suivi de la maturation sexuelle. L'augmentation de la biomasse a conduit à l'installation d'un second filtre biologique en avril 2014. La mortalité a été forte en 2013-2014 à cause de pathologies bactériennes et de nodules calcaires dans le rein. Les analyses histologiques des prélèvements effectués en juin 2013 ont montré un développement normal des gonades. Une troisième série de prélèvements a été réalisée en Juin 2014.

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.
