Rearing endangered atlantic salmon (Salmo salar) in modified marine aquaculture systems for population conservation in Eastern Canada
Bibliographic record
Abstract
We document the first known marine aquaculture farm established and dedicated to rearing wild-origin Atlantic salmon ( Salmo salar ) for population restoration. Juvenile salmon of a common lineage were collected from the wild in Fundy National Park, in Eastern Canada and reared in a captive marine environment using modified commercial aquaculture systems. Each year from 2015 to 2024, cohorts of mature fish were tagged at the marine farm and transferred by truck for release back into to the Upper Salmon River in Fundy National Park, at the time they would be naturally returning from sea to spawn the next generation. Our rearing and release strategy avoided high mortality during the marine life stage, which is the factor most limiting population recovery. Post-released adult salmon were observed returning naturally in subsequent years from 2016 to 2024. This work contributed to our objective to increase counts of returning adult salmon, which were otherwise absent from 1995 to 2007, following a population collapse. The scale of benefits from released and returning salmon require further quantification, but the current study provides a promising template for consideration and implementation by other jurisdictions that are facing futures without salmon, and the associated loss of benefits to ecosystems, community, and culture that follow.

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.
