Modelled fish catch from coral reefs estimates the relative size of coral reef fisheries catch. This catch is determined as a function of estimated reef productivity and fishing effort. A minor modifier to this basic model makes allowance for no-take fishing areas (where catches are zero) with a small buffer of potential enhanced fisheries in adjacent waters (spillover). It does not account for variability in the economic or social value of these fisheries. The estimation of coral-reef associated fisheries involves 4 steps: 1) Estimate the pristine potential maximum sustainable yield on coral reefs – reflecting the potential sustainable production of fish on healthy reefs; 2) Estimate the realistic potential MSY (Maximum Sustainable Yield) on coral reefs, in light of current reef condition (degradation) reducing productivity; 3) Estimate catch based on the potential MSY, adjusted by nearby population and available fishing area; 4) Catch values were reduced to zero (no catch) in the no-take zones while changing the potential catch in a surrounding 1km buffer was raised to the maximum value.<br><br>For more infomration please visit <a href="http://maps.oceanwealth.org/" target="_blank">The Mapping Ocean Wealth Explorer</a>.<br/><br>This data is provided by <a href="www.nature.org" target="_blank">The Nature Conservancy</a><br/>"

Modelled fish catch from mangroves models the benefits that humans derive from fish production by mangroves. It accounts for: 1) Potential fish production (of fish, crustaceans, molluscs and other fishery target species predicted to be produced by a pristine system, free from human influences); 2) Fish production (the amount of fish predicted to be produced by the system, considering the influence of human activities such as fishing, pollution and mangrove degradation are taken into account); 3) Modelled catch (the amount of fish predicted to be caught, accounting for socio-economic factors, particularly population density); and 4) Modelled value (the value of the modelled catch, measured as the market value of the fish caught, or measured in terms of the protein that the fishery produces for the people it feeds or the livelihoods it supports.<br><br>For more infomration please visit <a href="http://maps.oceanwealth.org/" target="_blank">The Mapping Ocean Wealth Explorer</a>.<br/><br>This data is provided by <a href="www.nature.org" target="_blank">The Nature Conservancy</a><br/>"
