Microfishing for Juvenile Bluegill: A Catch-and-Release Study on an Emerging Form of Recreational Angling
Bibliographic record
Abstract
Abstract Microfishing is an emerging form of predominantly catch-and-release recreational angling with the main target being diverse small-bodied nongame fish species and the early life stages of traditional game fish. While there has been an apparent increase in interest in microfishing, little is known about its impacts on fish and fisheries. Here we compared the effects of two hook sizes (i.e., a size 22 hook and a somewhat larger, yet still smaller than normal, size 12 hook) on aspects of injury, handling, and mortality for juvenile Bluegill Lepomis macrochirus (size range of 69 to 141 mm; n = 54 for each hook size). Hook size was determined to have a significant influence upon injury and mortality. The smaller hooks resulted in longer handling time, more extensive tissue damage arising from challenges of hook removal, and higher levels of short-term mortality (n = 12, 22%) than the larger hooks (n = 2, 4%). Additional research is needed to develop best practices and management strategies for this emerging form of recreational angling on a wider range of species.

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.
