Optimal Fishing Mortalities with Age-Structured Bioeconomic Model - A Case of NEA Mackerel

Ni, Yuanming - 2016

The effects of random environmental impacts on optimal exploitation of a fish population are investigated using both optimization and simulation, based on a discrete-time age-structured bioeconomic model. The optimization problem is solved as a non-linear programming problem in GAMS. First, a...

Can Demand-Side Interventions Rebuild Global Fisheries?

Deschenes, Olivier; Costello, Christopher; McDonald, Gavin - 2022

Despite recent improvements in the ecological status of wild-capture fisheries, a significant share (33%) of global marine stocks remains overexploited. While top-down management has been shown to work in many settings, there is growing interest in demand-side interventions, which work through...
