CORAL Campaigns to Protect Sharks

Sharks are commonly misunderstood and widely feared. These remarkable animals, however, are incredibly important for overall ocean health and, in particular, for coral reefs.

Sharks are often “apex” or top predators, helping to regulate species abundance and diversity while maintaining balance throughout an ecosystem. Studies have shown that coral reef ecosystems with high numbers of apex predators tend to have greater biodiversity and higher densities of individual species.

The loss of apex predators in a reef ecosystem upsets the natural food web and changes the composition of the reef community, eventually leading to the decline of critical reef species like herbivorous fish. With fewer herbivores, algae can become overgrown, suffocating the reef and reducing the number of available niches for fish species.

A recent report from the Australian Institute of Marine Science found that shark tourism accounts for approximately eight percent of the G.D.P of the island nation of Palau. The study showed that the roughly one hundred sharks inhabiting the most popular dive sites in the area were each worth $179,000 annually to the local tourism industry, giving each shark an approximate lifetime value of $1.9 million.

Despite their ecologic and economic value, shark populations are declining at an alarming rate. Roughly thirty percent of shark species are threatened or nearly threatened with extinction, and the status of another roughly fifty percent is unclear due to insufficient data.

Intense commercial fishing is largely to blame for the decline, and shark finning-the practice of removing a shark’s fins and discarding the rest of the animal to die at sea-is particularly rampant. This practice is driven by demand for shark fin soup, a delicacy that creates a lucrative market for shark fins. Over seventy million sharks are killed each year to support the shark fin trade.

• Shark populations are in trouble globally.• Shark fins are considered one of the most valuable food items in the world, reaching prices as high as US$700 per kg.• 73 million sharks are killed each year to support the shark fin trade.• The IUCN Red List of Threatened Species has assessed that 30 percent of shark and ray species are threatened or near threatened with extinction.• The decline in shark populations can lead to unpredictable consequences, including the collapse of important fisheries.

Because sharks reproduce late in life and bear few offspring, scientists fear that some severely depleted populations may take hundreds of years to rebuild. This alarming prospect has compelled conservationists, scientists, and government officials to join together to push for greater shark protection.

Recently, Palau and the Maldives have created shark sanctuaries by prohibiting commercial shark fishing in their countries’ exclusive economic zones. Honduras also implemented a shark fishing moratorium and Hawaii has now instituted a retention ban aimed at prohibiting the possession of shark fins in state waters. Additional shark sanctuaries and conservation policies are gaining momentum around the world.

CORAL is currently developing programs that will increase shark protection in our Indo-Pacific project sites. In Fiji, we are working with Fiji’s Ministry of Fisheries to determine the potential for increased shark protection in the region. We have also secured funding for a public awareness campaign in Raja Ampat, Indonesia, that will generate local support for shark protection. Both of these initiatives will educate communities about their vested stake in preserving healthy shark populations to support the coral reef ecosystems that provide them with food, income, and coastal protection.
