Abstract
According the autumn Canadian survey (2J+3K) and the Spanish 3NO survey, the roughhead grenadier total biomass indices would indicate a general increasing trend from 1995 onwards. The catch / biomass (C/B) indexes obtained using the Canadian autumn survey and the Spanish 3NO biomass index in the period 1995-2004 show a clear decrease trend from 1995 to 2004, due to an increasing trend in the survey biomass and a decreased of catches. The Z estimate from the catch curve based upon commercial catch at age data (1992-2004) was 0.355 for ages 8 to 20, the value estimate from the catch curve of the UE Flemish Cap survey (1994-2004) was 0.511 for the same ages and 0.394 for the catch curve of the Spanish 3NO survey data (1997-2004). The Separable VPA (Pope and Shepherd, 1982) stock assessment model was fitted to the stock data, years 1993 to 2004 and ages 3 to 20, for the roughhead grenadier Subarea 2 and 3. The model seems to fit adequately the data. The results of the Separable VPA were used to start a traditional VPA. The mean fishing mortality for ages 8 to 20 in the period 1993-2004 was 0.259 and is similar than those calculated by the catch curves with the catch matrix data (0.255) and with the Spanish 3NO survey data (0.294) for the same ages. Moreover the trend of F bar (8-14) of the VPA is similar to the catch/survey biomass ratio for the Canadian Autumn survey (2J3K) and the Spanish 3NO survey. However the VPA biomass trend is total different from the biomass trend of the Canadian Autumn (2J3K) and Spanish 3NO surveys, in the last years the biomass of the surveys show a great increase and the VPA biomass is stable at the lowest levels of the series. Recruits at age 3 have the same problem, survey show in 2004 the biggest recruitment of the series while VPA show for 2004 a normal recruitment.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
