Population Structure and Reproductive Biology of Lane Snapper, Lutjanus synagris (Lutjanidae) Caught in the Reef Fish Fishery of Pernambuco, Brazil
Bibliographic record
Abstract
Abstract Lane snapper Lutjanus synagis (Linnaeus 1758) is abundant in Northeastern Brazil and economically relevant to the artisanal fishery. Population and reproductive aspects of lane snapper wereinvestigated to assist assessment. Lane snappers were acquired in Pernambuco (n = 406) from 2013 to 2015. Sex ratio is close to 1 : 1 (213 males and 179 females). For males, the total length, TL (mode) ranges from 16.3–27.8 cm (20.4 cm). For females, TL ranges from 17.0–29.9 cm (21.0 cm). The species have negative allometric growth (b < 3). The length that 50% of the population reach maturity (L50) using TL is 17.7 cm for both sexes. Macroscopical and microscopical gonadal stages are described per sex, and the gonadosomatic index indicates that reproduction happens during the dry season, between September and March, and two maturational peaks are observed, the first between September and November and the second between January and March.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
