Biologia reprodutiva do camarão sete-barbas no litoral centro sul e sul do Espírito Santo, Brasil
Bibliographic record
Abstract
The size at first maturity, reproductive cycle, sex ratio and recruitment of the sea-bob shrimp Xiphopenaeus kroyeri were studied from monthly samples in two coastal areas of the Espírito Santo state between 2003 and 2004 in order to support sustainable management of this species. The samples were obtained with bottom trawls in small artisanal fishing boats from 4 to 8 m deep. A total of 6,006 specimens were captured, being 2,766 females, 3,182 males and 58 of undetermined sex. Females were significantly bigger than males. The average length of first maturation of females was 9.026 cm. Adult females predominated over males between December and February, coinciding with the spawning peak, while males predominated in the subsequent quarter. This alternation of proportions was associated with bathymetric migrations of reproductive females. The annual gonadal maturation cycle, seasonal abundance and sizes and recruits suggest the existence of continuous spawning and recruitment in December-February and in July and August. The difficulties of establishing a closed season in proper condition indicated that the management of the resource should receive more attention because of the issues involved, whether social, biological or environmental.

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.
