Describing new fish sounds from the northeast Pacific: A quantitative approach
Bibliographic record
Abstract
In order to identify fish sounds in British Columbia soundscapes, we need catalogues of validated fish sounds from Pacific species. These catalogues will help in comparing validated examples to unknown sounds found in long-term autonomous recordings. In addition, it is important that the sounds be described quantitatively for accurate identification and comparison. Our goal is to contribute to building such catalogues and to fill knowledge gaps in fish acoustic behaviour to support studies on the impact of anthropogenic noise on Pacific fishes. Since distinguishing sound sources in the ocean is extremely difficult, we are collaborating with aquaria, marine science centers and ocean-based aquaculture facilities to monitor, audition and record the acoustic behaviour of captive and semi-captive fish species. To date, we have acquired over 3,000 hours of recordings in these conditions. Sounds that we have already validated include Arctic cod (Boreogadus saida), walleye pollock (Gadus chalcogrammus), and grunt sculpin (Rhamphocottus richardsonii) vocalizations. Here, we will present a description of these newly validated sounds.

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.
