Andavadoaka, Madagascar Slideshow

In the Andavadoaka region of Madagascar’s southwest coast, the Vezo people have subsisted on the bounty of the Toliar Barrier Reef for centuries. But the lobsters, finfish, octopus, and coastal dolphins they depend on are growing scarce. WCS conservationists are working to establish marine fishery reserves to ensure this fragile seascape and the traditional livelihoods it supports remain intact.

In the waters just south of the Mozambique Channel that borders much of Madagascar’s west coast, traditional Vezo fishermen ply their trade from simple hand-carved wooden canoes, called "pirogues."

A fisherman swims a nets around a school of fish. Small-mesh fishing nets like this one can result in high levels of bycatch. WCS is working to promote more sustainable fishing gear.

Most of the fishing activity takes place within the nearest reaches of one of the world’s largest barrier reef systems, the Toliar Barrier Reef, since the pirogues cannot travel far. These reefs are among the most biodiverse in the Western Indian Ocean.

In addition to overfishing and destructive fishing practices, land pollution and the harmful effects of climate change can also have serious consequences for fragile coral reef ecosystems.

In addition to fishing, the Vezo people also hunt coastal dolphins and sharks in local waters. A growing global market for shark fins is depleting shark populations around the world.

Though the Vezo people have had very limited economic opportunities, tourists are beginning to visit new resorts in the area. WCS is working to ensure the tourism industry grows sustainably and with respect for this spectacular seascape.
