Macroinvertebrate community responses to clam aquaculture practices in British Columbia, Canada
Bibliographic record
Abstract
Despite recent growth of shellfish aquaculture in B.C., Canada, very little is known regarding impacts of common practices.Seeding and netting are frequently employed on clam farms to increase production of' Venerupis philippinarum.A pilot netting experiment found no observable effect of predation at small scales.A field study compared bivalve communities on clam farms with matched reference sites, using density and biomass data.V, philippinarum was the only species found in higher abundance on farm sites, consistent with values expected from clam seeding.Bivalve communities were not significantly different on farm sites, but were more similar on average than reference sites, leading to a loss of regional distinctness.These results are consistent with recent research suggesting that predation and competition may play minor roles in structuring communities in soft-bottom environments.Given the remaining uncertainties, a precautionary approach is recommended in future development of the intertidal for clam aquaculture.iii

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.
