Marine Ecology: Reserves Do Have a Key Role in Fisheries
نویسنده
چکیده
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.

Effects 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 ...
متن کاملRoles of experimental marine ecology in coastal management and conservation.
The paper reviews the main findings of rocky shore and subtidal nearshore experimental marine ecology (EME) in cold and temperate marine ecosystems during the past four decades. It analyzes the role of EME in coastal management and conservation. The historical development of strategies for managing single or multispecies fisheries are reviewed. The published results show over-exploitation and d...
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 کاملMatching marine reserve design to reserve objectives.
Recent interest in using marine reserves for marine resource management and conservation has largely been driven by the hope that reserves might counteract declines in fish populations and protect the biodiversity of the seas. However, the creation of reserves has led to dissension from some interested groups, such as fishermen, who fear that reserves will do more harm than good. These perceive...
متن کاملThe Role of Pre-Existing Disturbances in the Effect of Marine Reserves on Coastal Ecosystems: A Modelling Approach
We have used an end-to-end ecosystem model to explore responses over 30 years to coastal no-take reserves covering up to 6% of the fifty thousand square kilometres of continental shelf and slope off the coast of New South Wales (Australia). The model is based on the Atlantis framework, which includes a deterministic, spatially resolved three-dimensional biophysical model that tracks nutrient fl...
