Summer Ecosystem RV Survey Trends- Scotian Shelf and Bay of Fundy
Bibliographic record
Abstract
Fisheries and Oceans Canada (DFO) has conducted the Maritimes Summer Ecosystem Research Vessel Survey (herein, Summer Ecosystem RV Survey) in Northwest Atlantic Fisheries Organization (NAFO) Divisions 4VWX and DFO statistical unit area 5Yb using a standardized protocol since 1970. Results of these surveys provide information on trends in abundance for most groundfish species in the Maritimes Region. While these data reflect trends in biomass and abundance and are a critical part of science-based stock assessments, a full assessment, including other sources of data, would be required to evaluate the impacts of management measures on population status. DFO Resource Management requested a review of the Summer Ecosystem RV Survey information on the following list of fish stocks: 4Vn, 4VsW, and 4X5Y Atlantic Cod; 4VW and 4X5Y Haddock; 4X and 4VW White Hake; 4VWX Silver Hake; Western and Eastern Component Pollock; 4VWefghj and Unit III redfish; 4VWX Atlantic Halibut; 4VW and 4X American Plaice; 4VW and 4X Witch Flounder; 4VW and 4X Winter Flounder; 4VW and 4X Yellowtail Founder; 4VW and 4X Smooth Skate; 4VW and 4X Thorny Skate; 4VW and 4X Barndoor Skate; 4VW and 4X Winter Skate; 4VW and 4X Little Skate; 4VW and 4X Atlantic Wolffish; 4VW and 4X Monkfish; 4VW and 4X Longhorn Sculpin; 4VWX Spiny Dogfish; 4X and 4VW Red Hake; 4X and 4VW Sea Raven; 4X and 4VW Ocean Pout; 4VWX Blackbelly Rosefish; 4VWX John Dory; and 4VWX Shortfin Squid. In addition, biomass trends were requested for 4X and 4VW White Hake for lengths above 41 cm relative to the Scotia Fundy Groundfish Advisory Committee (SFGAC) accepted biomass reference points. The survey information will be used by DFO Resource Management as background for discussions with various stakeholders on recommendations for management measures and to determine which stocks should be reviewed in more detail in 2025. In addition, available survey information was reviewed for Black Sea Bass, Dusky Shark, Triggerfish, and Tilefish. These species are being captured as bycatch in commercial fishing operations but are not covered under any license conditions and cannot be landed. This Science Response Report results from the regional peer review of December 10, 2024, on the Update of Trends from the Maritimes Ecosystem Research Vessel Survey - Scotian Shelf and Bay of Fundy.

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.
