Large-scale, seasonal movements of radiotagged, adult bull trout in the St. Mary River drainage, Montana and Alberta
Bibliographic record
Abstract
Radio telemetry was used to determine the large-scale, seasonal movements and wintering areas of adult bull trout (Salvelinus confluentus) in the St. Mary River drainage, Montana and Alberta, between 1998 and 2003. The fish (n = 42; total length, 434-763 mm) had been radiotagged in their spawning creeks (river tributaries) during August-October. Data from automated, stationary radio receivers operated adjacent to the river showed the post-spawning and subsequent pre-spawning movements of tagged bull trout occurred during October-November and May-July, respectively. Searches conducted from the ground and aircraft during winter (December-April) found tagged fish (n = 22) distributed in the St. Mary River between the mouth of Lee Creek (Alberta) and Lower St. Mary Lake (Montana), and in the tributaries (n = 15 fish). Maximum stream distance between contact locations for individual fish (median, 25.5 km; range, 1-83 km) was not associated with fish length or weight when tagged. Some bull trout passed the St. Mary River diversion dam, although passage timing was not precisely determined and may have occurred when the dam was open. Nevertheless, upstream passage of some bull trout appeared to be impeded by the dam during pre-spawning movements, when the dam was closed for the irrigation season.

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.
