Impact of two of the world's largest protected areas on longline fishery catch rates
John Lynham e outros, 2020 · Nature Communications
Expanding the Pacific Remote Islands monument increased tuna catch per 1,000 hooks by 0.564 fish in the Hawaii longline tuna fleet relative to the control fleet.

Contexto
What changed: The Pacific Remote Islands Marine National Monument was expanded in 2014, closing large ocean areas to commercial fishing. Comparison: Difference-in-differences comparing Hawaii-based longline tuna trips before and after expansion against Hawaii swordfish trips targeting different species in the same region. Limits: Relies on parallel trends between target and bycatch catch rates across distinct gear settings, though controlled for vessel fixed effects and El Niño oceanographic conditions.
