Abstract
The growth of different Life phases and social categories of the protogynous parrotfish Sparisoma viride was studied on a fringing reef on Bonaire (Netherlands Antilles) using mark-recapture procedures and by taking repeated stereographic measurements of free-swimming fish. Weight-growth was best described by the Putter/von Bertalanffy growth equation for all categories, allowing comparison of specific growth rates (dW/Wdt) using analysis of covariance with W-(1/3) as the covariate. Growth was retarded by Peterson discs, but no effect of fin clips was detected. Adjusted for size differences, growth of juveniles was fastest, followed by sexually inactive terminal phase (TP) males living in groups. Initial phase (IP) females and territorial TP males (spawning daily) showed the lowest growth rates. Growth rate of territorial males was negatively correlated with their average spawning rate. All adult categories showed seasonal variations in growth, the highest rates occurring in the warmest season (August to October). A possible effect of depth on growth is confounded by differences in social and reproductive status. Growth of group TP males showed a weak positive correlation with their condition. Gross growth efficiencies were estimated by combining data on growth and body composition with previously published data on food intake and assimilation. Growth efficiency is highest for protein, ranging from 50.6% of food intake for juveniles to 0.12% for territorial males. Corresponding values are 6.25 to 0.01% for ash-free dry weight and 7.9 to 0.01% for energy. The high abundance of small, sexually inactive group TP males (early sex-changers) in our S. viride population is related to their fast growth. We suggest that these 'bachelors' trade growth against current reproduction and thereby enhance their chance to acquire the status of a territorial male with high reproductive success. Insight into intraspecific variation in growth improves the accuracy of trophodynamic models and increases our understanding of complex Life history patterns in fish.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
