Age structure,sex ratio and growth of the Taimen(Hucho taimen) in Wusuli River
Bibliographic record
Abstract
We report the current status of Taimen (Hucho taimen) population in Wusuli River of China. The amount of catch per year was only 1 800 - 5 400 individuals ranging from 2-15 years old during 1998-2002. Of all the captured, individuals with sexual maturity were up to 30%-70% (female maturity at 5 years old and male 6 years old). Sex ratio varied greatly among different localities. Its breeding population mainly consisted of males aged 5-10 years and females aged 8-13 years'old, which spawned in May each year.Females breed once with about 4 000 - 23 000 eggs produced every 2-3 years. Taimen grows fast and average growth rate is about 10 cm per year prior to 10 years's old, which corresponded with von Bertelanffy's equation calculated as L t=246 41[1-e -0 0407(t-0 4625) ] and W t= 174 075 72 [1-e -0 0407(t-0 4622) ] 2 9537 , and the relationship between body length and weight was W=0 015018L u 2020 .

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.
