Bioeconomic losses from overharvesting tuna
Stochastic dynamic programming is used to model the world's largest fishery-tunas of the western and central Pacific-and to show that adopting a biomass target that maximizes the discounted economic profits (BMEY) from harvesting would result in larger stocks compared to de facto biological targets, and also lower catches relative to business as usual. This result is obtained for the three major tuna species, including skipjack tuna, which is not currently considered to be overfished...[Show more]
