Fecundity and Sexual Maturity in Select Nova Scotia Trout Populations
Bibliographic record
Abstract
ii Fecundity, sexual maturity and general reproductive life history traits of native brook trout Salvelinus fontinalis and introduced brown trout Salmo trutta, in lotic and lentic habitats of Nova Scotia, were examined. Age at first maturity of brook trout was 1+ years and older and for brown trout was 2+ years and older. Fecundity of brook trout and brown trout was slightly higher than that expressed in literature. Expected number of eggs for a 250mm mature trout was 558 for lake-dwelling brook trout, 586 for stream-dwelling brook trout and 466 for stream-dwelling brown trout. Maturity was positively correlated with trout length, however lake-dwelling brook trout exhibited greater variation in length at maturity than stream-dwelling brook trout and brown trout. For brook trout, the length at which the probability of maturity was 50 % was 196 mm in lake and 188 mm in stream habitats. Brown trout matured at a larger size than did brook trout and length at 50 % maturity was 236mm. Implications of these data are discussed with a

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.
