BLUEFIELDS BAY, Jamaica (AP) — Young fish leap in the wake of a warden’s patrol boat as it motors through waters off Jamaica’s southwest coast that are a brilliant palette of blues. Beneath the surface, reefs bristle with spiny lobsters, and rainbow-colored parrotfish graze on algae and seaweed.
After rampant destruction of local fish habitats over decades, marine life is gradually rebounding in Bluefields Bay now that every minnow and mullet, each sea urchin and snapper is protected from spear guns and nets. This 6½-mile (10-kilometer) long stretch of water, patrolled daily by a small team of wardens and marine police, is one of a growing number of no-fishing zones in the Caribbean, where most coastal reefs have been severely damaged by overfishing, pollution, and more recently global warming.
“If we want to protect our future, setting up more places like this is a no-brainer. If we keep destroying areas with thousands of baby and juvenile fish, where will the big fish come from tomorrow?” said Wolde Kristos, chairman of the Bluefields Bay Fishermen’s Friendly Society that lobbied Jamaica’s government to create the reserve, the biggest and most robustly enforced of the island’s 14 fish sanctuaries.
Across the Caribbean, governments and fishing communities are beginning to use such “no-take” zones to help rebuild severely depleted fish stocks and make coastal ecosystems more resilient to a warming planet and acidifying oceans.
No-take areas that expand on less-restrictive marine protected areas have become a growing trend, with U.S. states and nations across the world barring fishing boats from areas that sometimes cover well over 100,000 square miles (300,000 square kilometers).
In the tourism-dependent Caribbean, conservationists say about 17 million acres (6.8 million hectares), or just over 2 percent, of marine and near-shore resources such as mangroves are protected in some way. And no-take reserves with the highest level of protection are starting to catch on.
The Bahamas boasts the region’s largest fishery reserve with the 176-square mile (455 square kilometer) Exuma Cays Land & Sea Park. They’re also found in places such as the U.S. Virgin Islands, Belize and the Cayman Islands.
But many protected areas now amount to little more than lines on a map. A recent study by the World Resources Institute, a Washington, D.C.-based environmental think tank, found that many marine protected areas are essentially “paper parks,” without adequate resources to enforce various restrictions.
Even in well-patrolled reserves such as Bluefields Bay, poachers still try to sneak in at night. And just outside the boundaries, a few subsistence fishermen occasionally blow up reefs with dynamite in order to send fish belly up, Kristos said.
While most of the Caribbean reserves are relatively tiny, “There’s little question that small reserves can help recover a number of important species, including grouper. This can help with biodiversity and keeping reefs healthier inside the reserves,” said Peter Mumby, a marine ecologist who has studied the Exuma Cays no-take zone.
His team found that coral cover grew significantly faster inside the reserve than outside. That’s a big deal in the Caribbean, where the International Union for Conservation of Nature says live coral coverage on reefs is down to an average of just 8 percent, from 50 percent in the 1970s.
Such protected, intact coral reef systems have been shown to be “more resistant to ocean warming and other effects of climate change,” according to Mark Hixon, a marine biologist at the University of Hawaii. That’s largely because they have more and more varied living creatures.
