Ecosystem-based Management of Coral Reef Fisheries
Issue 1: MPA benefits to fisheries It is crucial to avoid ‘overselling’ MPAs on the basis that increased catches due to spillover and enhanced recruitment from spawning in the MPA will more than make up for lost fishing grounds, increased effort and higher costs of fishers displaced from the MPA. To date, this assumption has never been proven; and spillover is generally measured as movement of ...
متن کاملLag effects in the impacts of mass coral bleaching on coral reef fish, fisheries, and ecosystems.
Recent episodes of coral bleaching have led to wide-scale loss of reef corals and raised concerns over the effectiveness of existing conservation and management efforts. The 1998 bleaching event was most severe in the western Indian Ocean, where coral declined by up to 90% in some locations. Using fisheries-independent data, we assessed the long-term impacts of this event on fishery target spec...

متن کاملCurrent and Future Sustainability of Island Coral Reef Fisheries
Overexploitation is one of the principal threats to coral reef diversity, structure, function, and resilience [1, 2]. Although it is generally held that coral reef fisheries are unsustainable [3-5], little is known of the overall scale of exploitation or which reefs are overfished [6]. Here, on the basis of ecological footprints and a review of exploitation status [7, 8], we report widespread u...
متن کاملLinking Social and Ecological Systems to Sustain Coral Reef Fisheries
The ecosystem goods and services provided by coral reefs are critical to the social and economic welfare of hundreds of millions of people, overwhelmingly in developing countries [1]. Widespread reef degradation is severely eroding these goods and services, but the socioeconomic factors shaping the ways that societies use coral reefs are poorly understood [2]. We examine relationships between h...
