Abstract
While aquaculture is increasing worldwide, there are concerns on the east coast of Canada about the influence of finfish aquaculture sites on crustacean distribution patterns. This study evaluated the abundance and movement of American lobsters Homarus americanus and rock crabs Cancer irroratus in the vicinity of 2 salmonid aquaculture leases in Liverpool Bay and Port Mouton, Nova Scotia. The study was done over a full 3 yr production cycle in Liverpool Bay. In Port Mouton, the study was done over 4 mo in 2019, 4 yr after salmonid production had ceased. Each year, around 50 lobsters and 50 crabs were tagged with acoustic transmitters and released at an existing fish farm or at 1 of 2 reference sites. Tagged lobsters travelled throughout Liverpool Bay and showed little affinity to the farm, as most lobsters caught and released adjacent to or below the farm did not stay in the area over time, and their home ranges did not exhibit much overlap with the farm. Very similar patterns were observed for lobsters released in the reference areas and in Port Mouton sites. In contrast, rock crabs moved more slowly than lobsters and seemed to be associated with the farm in Liverpool Bay, as their home ranges had a high overlap with the farm for crabs tagged directly under it. Overall, both rock crab and lobster associated with the Liverpool Bay aquaculture site, although the degree of association varied by species with rock crabs being much more attracted to the area under the farm.

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 it
