An Ecosystem Framework for Fisheries Management in the Southern Benguela Upwelling System
casted the increasing need for fisheries managers to take species interactions into account. It is now widely recognized that ecosystem effects need to be considered in managing fisheries (Pauly 1998, Beamish and Mahnken 1999, Gislason et al. 2000). Steele (1996) concluded that a “regime shift in fisheries management” is required if one is to manage fisheries successfully in the context of ecos...
متن کاملResponse of Rocky Reef Top Predators (Serranidae: Epinephelinae) in and Around Marine Protected Areas in the Western Mediterranean Sea
Groupers species are extremely vulnerable to overfishing and many species are threatened worldwide. In recent decades, Mediterranean groupers experienced dramatic population declines. Marine protected areas (MPAs) can protect populations inside their boundaries and provide individuals to adjacent fishing areas through the process of spillover and larval export. This study aims to evaluate the e...
متن کاملMarine protected areas and the governance of marine ecosystems and fisheries.
Marine protected areas (MPAs) are spatially defined marine units in which one or more human activities— particularly fishing—are restricted or prohibited. They represent a precautionary and ecosystem-based approach to ocean management (Mangel 2000; Pikitch et al. 2004; Jones 2006). The 1992 Convention for Biological Diversity set a target for 10% of the global marine area to be designated as MP...
متن کاملGuidelines for Marine Protected Areas
These Guidelines are designed to be used in association with other publications which cover relevant subjects in greater detail. In particular, users are encouraged to refer to the following: Founded in 1948, The World Conservation Union brings together States, government agencies and a diverse range of non-governmental organizations in a unique world partnership: over 900 members in all, sprea...
متن کاملModels and indicators for assessing conservation and fisheries-related effects of marine protected areas
Two kinds of approaches have been used for assessing conservation and fisheries-related effects of marine protected areas (MPAs): (i) statistical modelling based on field data and (ii) mathematical modelling quantifying the consequences of MPAs on the dynamics of populations, communities, and fisheries. Statistical models provide a diagnostic on the impact of MPAs on the ecosystem and resources...
