Use of micro‐PIXE to investigate otolith Sr distributions of the anadromous striped bass, <i>Morone saxatilis</i>
Bibliographic record
Abstract
Abstract Migration patterns of anadromous Atlantic coast striped bass, Morone saxatilis , have been determined primarily through mark and recapture studies. These studies provide little information about the duration, seasonality and frequency of estuarine and ocean migratory phases of migration, nor have they identified the age at which striped bass first exhibit anadromy. In order to investigate how otolith Sr distributions can contribute to these aspects of fish life histories, otoliths from striped bass of the Roanoke‐Albemarle Sound, North Carolina population were analyzed using a scanning proton microprobe (micro‐PIXE). The results suggest that micro‐PIXE can provide detailed information about migration patterns for this population. Differences in striped bass migration were observed. Two fish exhibited emigration to ocean habitats at 2 years of age. Interestingly, the two movement patterns observed, one resident and one migratory, were related to the three major genotypes (mtDNA) of this population, suggesting that timing and appearance of anadromy might be related to lineage for this species. Additional sampling will be necessary in order to confirm this hypothesis. Copyright © 2005 John Wiley & Sons, Ltd.

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.
