Marine Ecology: Reserves Do Have a Key Role in Fisheries
A new study of the Great Barrier Reef proves a 100-year old conjecture correct: marine reserves do replenish populations in surrounding fishing grounds, while modern reserve networking theory is validated by exchange of offspring of animals among protected areas.
متن کاملThe role of marine reserves in achieving sustainable fisheries.
Many fishery management tools currently in use have conservation value. They are designed to maintain stocks of commercially important species above target levels. However, their limitations are evident from continuing declines in fish stocks throughout the world. We make the case that to reverse fishery declines, safeguard marine life and sustain ecosystem processes, extensive marine reserves ...
متن کاملThe Role of Marine Reserves as Fisheries Management Tools
I N T E R N A T I O N A L E X P E R I E N C E Around the world many fisheries have collapsed, including some in Australia. Consequently marine fisheries are under increasing pressure to adopt more precautionary management approaches. Although Australia’s fisheries are generally in good shape—few are overfished—many are fully exploited. Overseas experience tells us that even the best fisheries m...
متن کاملIrreducible uncertainties, sustainable fisheries and marine reserves
Marine reserves are increasingly proposed as a management tool. Models can play a valuable role in the evaluation of the possible benefits of reserves because they allow us to conduct many more investigations than could ever be done empirically. In this paper, I develop a model for a marine reserve for an open population subject to environmental uncertainty.
متن کاملEffects of marine reserves on adjacent fisheries.
Marine reserves have been widely promoted as conservation and fishery management tools. There are robust demonstrations of conservation benefits, but fishery benefits remain controversial. We show that marine reserves in Florida (United States) and St. Lucia have enhanced adjacent fisheries. Within 5 years of creation, a network of five small reserves in St. Lucia increased adjacent catches of ...
