Round goby detection by scuba divers’ visual assessments and environmental DNA in the Great Lakes, 2022
Bibliographic record
Abstract
This dataset is associated with an examination of environmental DNA (eDNA) from the invasive round goby (Neogobius melanostomus) in parallel with visual surveys of fish count and size conducted by scuba divers in four Great Lakes: Michigan, Huron, Erie, and Ontario. Round goby inhabits benthic areas, and it is known to have direct contact with the bottom substrate as it feeds on dreissenid mussels. Considering this, eDNA samples were derived from multiple substrates: lake bottom water, sediment, and benthic algae; each manually collected by scuba divers from 3 or 6-meter depths and eight distinct transects. eDNA samples were analyzed by droplet digital PCR (ddPCR) and results are expressed as DNA Copy Numbers (CN) per 1 mL of water or per 1 gram of wet weight of sediment or benthic algae. All eDNA samples for this dataset were collected alongside a larger body of work conducted in 2022 (https://doi.org/10.5066/P13JDUMH) and relate to multiple years of work at these stations that includes: algal and dreissenid mussel biomass, water quality assessments, and diver observations of dreissenid mussels, round gobies, benthic substrate, and benthic algal cover. We refer to the benthic algae also as the ‘Cladophora community’ and ‘submerged aquatic vegetation (SAV)’ in other published project data, which were collected starting in 2018 (Great Lakes Science Center, 2018).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
