Survival and Growth of Lake Whitefish from Two Stocking Strategies in Lake Simcoe, Ontario
Bibliographic record
Abstract
Abstract To determine the more efficient stocking strategy for lake whitefish Coregonus clupeaformis in Lake Simcoe, Ontario, we compared growth and survival of fish stocked as fall fingerlings and as spring yearlings. Paired lots were stocked in April and October from the 1986 to 1991 year-classes. Survival and growth of fish from the two rearing practices were indexed as the relative abundance and length of 6-year-old lake whitefish captured with trap nets during fall spawning runs from 1992 to 1997. No difference in relative abundance or length between lake whitefish stocked at 6 months of age and those stocked at 12 months of age was detected. This contradicts results reported for many other fish species, which have exhibited greater survival rates when stocked as yearlings rather than fingerlings. As a result of these findings, all lake whitefish stocked into Lake Simcoe are stocked in the fall when the fish are 6 months of age, thus freeing up limited hatchery space for other purposes.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
