The effects of an experimental freshwater cage aquaculture operation on Mysis diluviana
Bibliographic record
Abstract
We utilized 7 years of data to determine the influence of decreased concentrations of hypolimnetic oxygen and increased densities of phytoplankton and fish on the mysid Mysis diluviana in a whole-lake experiment on the effects of cage aquaculture for rainbow trout (Oncorhyncus mykiss). Following establishment of the cage farm in 2003, densities of Mysis decreased from an annual average of 85 m−2 (2002–2005) to 7 m−2 in 2007–2008. This decline was strongly correlated with decreasing concentrations of hypolimnetic oxygen. Spatially, Mysis were restricted to stations overlying bottom waters with temperatures colder than 12°C and oxygen concentrations >1 mg L−1 so that Mysis occupied a progressively smaller fraction of the lake as O2 declined in the hypolimnion. In a nearby reference lake, Mysis densities varied considerably among years (27–112 m−2), but never fell as low as in the experimental lake. Mysis growth rates did not vary between the reference lake and the experimental lake. Our results indicate that declines in hypolimnetic oxygen associated with nutrient enrichment can have severe impacts on populations of Mysis.

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.
