MPA Mania

Marine Protected Areas (MPAs, a.k.a. green zones) are a current fad in marine resource management (and yes, science does have its fads). Where renewable resources are overexploited some form of restriction. is desirable. MPAs are but one of a range of restrictive measures that may be employed. Whether they offer any advantage or disadvantage to closed seasons, catch limits, limited licensing or other restrictions has not been assessed.
