Remotely operated vehicle surveys of rockfish conservation areas in British Columbia, February 2009–July 2011
Bibliographic record
Abstract
As part of an overall Rockfish Conservation Strategy in British Columbia (BC), Canada, new spatial management measures were designated, the later referred to as Rockfish Conservation Areas (RCAs), which prohibited most recreational and commercial fishing within their boundaries. Between 2002 and 2007, 164 RCAs were implemented throughout the BC coast. Non-intrusive visual surveys were then developed to study fish communities and assess stock status and habitat of inshore rockfish. Between 2009 and 2011, seven visual surveys were conducted at 47 RCAs and adjacent fished areas in southern BC using a Deep Ocean Engineering Phantom HD2+2 remotely operated vehicle (ROV). In total, 424 transects were completed in a paired sampling design over similar rockfish habitat both inside and adjacent to the RCAs. This technical report provides a summary of the visual surveys used to initially assess RCAs in BC and details the methods used to plan the visual survey transects, collect visual data, analyze recorded video, process the transect track lines, and manage the database

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.
