Individual Vessel Quota Price‐induced Effects for Canadian Pacific Halibut: Before and After Alaska IFQs
Bibliographic record
Abstract
Two significant management changes have affected the British Columbia Pacific halibut fishery. The first was the implementation of the British Columbia individual vessel quota (IVQ) program in 1991, which tended to increase ex vessel prices. The second was Alaska's decision to follow its own individual fishery quota program in 1995, which tended to decrease British Columbia ex vessel prices. In a previous journal paper, the market driven ex vessel price increases for the British Columbia IVQ halibut fishery was estimated for 1991–1994. This paper examines the price‐ induced effects from 1995 to 1998 and quantifies how much of the previous price‐induced IVQ increases remained after Alaska went to IFQs. Results indicate that approximately one‐half of the price advantages of the British Columbia IVQ system was lost after Alaska went to the IFQs. However, a substantial revenue advantage remains, with the revenues estimated to have been $16.1 million higher during 1995–98 than would have occurred if both the British Columbia and Alaska had not put the individual quota programs into place. This brings the estimated total eight‐year British Columbia Pacific halibut revenue increase due to IVQs at $39.5 million. Deux grands changements de gestion ont bouleversé le secteur de la pêche du flétan du Pacifique en Colombie‐Britannique. Le premier a été la mise en place, en 1991, du contingent individuel de prises par vaisseau (IVQ) qui a eu pour effet général d'accroître les prix du poisson au débarquement. Le deuxième a été l‘adoption par l'Alaska en 1995 de son propre programme de contingent individuel de pêche, qui a eu en général un effet négatif sur les prix des poissons débarqués en Colombie‐ Britannique. L'avantage du programme IVQ était qu'il permettait de mettre en marché un produit de meilleure qualité durant la presque totalité de l'année. Dans un article précédent, nous examinions les effets des prix résultant du programme IVQ pour les années 1991 à 1994. Nous examinons id les effets pour les années 1995 à 1998 et nous quantifions la pan des accroissements d'IVQ générés par les prix qui subsistait après que l'Alaska ait adopte son propre régime. Il semble qu'approximativement la moitié de l‘avantage de prix obtenu par le régime IVQ de la Colombie‐Britannique ait été perdue avec l'entrée en application du régime de l'Alaska. Il reste encore, cependant, des avantages subtantiels, comme en fait foi le niveau plus élevé des revenus de la pêche du flétan, qui ont été de 16,1 millions de dollars canadiens plus élevés dans la période 1995–1998 que si aucun des deux regimes de contingentement n'avait pas été mis en place. L'accroissement global pour la Colombie‐Britannique des recettes tirées de la pêche du flétan du Pacifique depuis l'adoption du IVQ en 1991 s'établit donc à 39,5 millions de dollars canadiens.

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.
