SFA 4, EAZ, and WAZ Striped Shrimp Stock Assessment in 2024
Bibliographic record
Abstract
Status SFA 4: In 2024, Striped Shrimp fishable biomass (FBpop) was estimated to be 2.8 times the LRP for SFA 4. The population-wide potential predator index is at a time-series high in 2024, but other indices of stock health showed no cause for concern. Striped Shrimp in SFA 4 is considered in a healthy state. EAZ: In 2024, Striped Shrimp was estimated to be in the Healthy Zone of the PA Framework, above the USR with a 91.5% probability. WAZ: In 2024, Striped Shrimp was estimated to be in the Healthy Zone of the PA Framework, above the USR with a 98.0% probability. Trends SFA 4: In 2024, the SSB index increased by 6% (to 25,000 t) since 2023, and is slightly above the long-term mean (2005–23). The SFA 4-specific FB index has decreased by 26% (to 28,600 t) since 2023, and is slightly below the long-term mean (29,600 t). EAZ: The female SSB and FB indices in the EAZ have increased since 2023, by 97.5% (to 13,488 t) and 11.2% (to 15,724 t), respectively. These indices are above the long-term mean (2009–23) and reference period mean (2009–19). WAZ: The female SSB and FB indices in the WAZ have increased since 2023, by 65.3% (to 65,704 t) and 7.7% (to 72,644 t), respectively. These indices are above the long-term mean (2014–23) and reference period mean (2014–19). Ecosystem and Climate Change Considerations In SFA 4, the EAZ, and WAZ, summer ocean bottom temperatures for 2024 were close to average to slightly warmer. The potential predator index representing the assessment area has increased in recent years to a time-series high in 2024. Stock Advice SFA 4: The preliminary ERI for 2024/2025 was 10.4%, with 74% of the bycatch limit taken. If the full bycatch limit is taken in 2024/2025, the ERI will be 14.1%. EAZ: The preliminary ERI for 2024/2025 in the EAZ was 1.6%, with 11.1% of the TAC taken. If the full TAC is taken in 2024/2025, the ERI will be 14.1%. WAZ: The preliminary ERI for 2024/2025 in the WAZ was 6.0%, with 28% of the TAC taken. If the full TAC is taken in 2024/2025, the ERI will be 21.2%.

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.
