Study shows that larger marine reserves are needed
Leading international marine scientists have called for the protection of more, large marine wilderness areas in a bid to shield the world’s dwindling stocks of fish from destruction.
Working in the world’s largest unfished marine reserve, the remote Chagos Archipelago in the central Indian Ocean, scientists from Australia and the US have shown there is a dramatic difference in the numbers, size and variety of fish compared with smaller marine parks.
Their findings in two new reports provide the world’s first clear evidence that large-scale marine wilderness reserves are better for conserving fish than the far more common, small marine protected areas (MPAs) that many governments and fishing communities are presently implementing.
“The bottom line is that we found six times more fish in the Chagos ‘no take’ area than we did in even the best-managed Marine Reserves elsewhere in the Indian Ocean,” says lead author of the reports, Dr Nick Graham of the ARC Centre of Excellence for Coral Reef Studies and James Cook University.
The researchers acknowledge that marine reserves closer to centres of human population require different kinds of management and need to be smaller, to ensure that people can still draw their livelihoods and food from the sea – and these smaller marine reserves also provide important conservation gains.
