Are marine reserves and harvest control rules substitutes or complements for rebuilding fisheries?

tHarvest control rules and no-take marine reserves are two man-agement approaches increasingly advocated as effective meansof rebuilding depleted fish stocks and averting the collapse offisheries. We incorporate the two approaches into a bioeconomicmodel and evaluate how they act as substitutes and/or com-plements when used together in fisheries stock recovery plans.Simulations of the model with estimated parameters from an actualfishery show that the cost of adopting a harvest strategy of slowstock rebuilding can be offset or substituted by a no-take reserve.For each of the harvest strategies explored, we find there is a rangeof reserve sizes that can act as a complement in a stock recoveryplan such that a no-take reserve improves both the profitabil-ity of fishers and average annual harvest during stock rebuilding.We demonstrate that a stock recovery plan that incorporates bothharvest control rules and no-take reserves can simultaneously con-tribute to conservation, economic and socio-economic objectives offisheries management.
