USING QUALITY-AUGMENTED GEDD TO ANALYZE PELAGIC LONGLINE FISHERY REGULATIONS

Fisheries managers seek cost-effective regulations to reduce bycatch in pelagic longline fisheries. Developing cost-effective regulations is complicated by significant price heterogeneity across longline species and across quality grades within species. General Equilibrium Derived Demand (GEDD) analysis measures the net economic impacts of regulations affecting the landings of multiple, interrelated species. We extend GEDD analysis to capture the economic impacts of regulations affecting catch quality as well as catch quantity. The modeling framework is used to analyze the potential for improvements in catch quality to offset reductions in catch quantity in regulated longline tuna fisheries.
