Inoculation Experiments to Understand Mass Mortalities in Sea Scallop, Placopecten magellanicus
Bibliographic record
Abstract
In 1993, sea scallop, Placopecten magellanicus, populations from the Jacques Cartier Bay on the North Shore of the Gulf of St-Lawrence of Canada, experienced masse mortality episodes with mortality rates reaching 80%. Both natural beds and aquaculture stocks were affected. Experiments were undertaken to determine if an unknown or unidentified pathogen could be responsible for the disease and if that disease was transmissible. Three experiments, in which scallops were inoculated with homogenate extracted from moribund and healthy scallop tissue, were carried followed by histopathological analysis. The results demonstrated that the scallops from the Lower North Shore were more vulnerable to external factors such as manipulations and injections than the scallops from other regions, like Magdalen Islands and Gaspésie. The histopathological analysis did not permit to identify the causal pathogenic agent but our results suggested transmission of infection. The exact cause of the mass mortality episodes remains unknown to date, but it could be caused by a combination of multiple factors including geographic distribution and inbreeding.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
