An exploratory assessment of burbot (Lota lota L.) by-catches in four northern Canadian lakes with respect to the viability of liver oil processing
Bibliographic record
Abstract
Burbot (Lota lota L.) liver oil with its high content of omega-3 fatty acids, Vitamin D and Vitamin K is a potentially-valuable nutritional therapeutic product. There is no commercial burbot fishery in Canada presently. Burbot by-catch was monitored during 2006 in four northern Canadian lakes to determine if a by-catch strategy might provide sufficient burbot for the establishment of a viable burbot liver oil processing facility. In the winter months, the burbot by-catch fishery was found to be about 15% of the lake whitefish (Coregonus clupeaformis) catch. In contrast, summer by-catch test fishery showed the burbot by-catch yield to be 3–7% of lake whitefish catch. Application of the highest by-catch value (i.e., from winter fishing) to the allowable quota catches of whitefish in these four lakes would result in a yield of only about 700 kg of burbot liver oil annually. This quantity would eliminate by-catch as a feedstock strategy for the prospective burbot liver oil processing business.

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.
