Coral reefs on which fish stocks have dropped below 300 kilograms per hectare are likely to collapse and lose their productivity, according to researchers.
They say that this figure provides an indicator of the 'tipping point' for sustainable fishing.
The researchers' conclusion, published in Proceedings of the National Academy of Sciences (PNAS) last month (11 October), is based on an analysis of the relationship of fish biomass to the health of coral reefs in more than 300 shallow coral reefs in nine countries of the Western Indian Ocean, including Kenya, the Maldives, the Seychelles and Tanzania.
