Status <strong>of</strong> <strong>Coral</strong> <strong><strong>Reef</strong>s</strong> in the Northern Caribbean and Atlantic Node <strong>of</strong> the GCRMN<br />

fishery situation. There are no minimum or maximum size limits or quotas for fishes, but<br />

landings are small and mostly consumed locally. There are 4 trap boats fishing for lobster<br />

and fishes, and only 2 boats operating in deep water; all other fishing is done by free<br />

diving from small boats. Hotels and restaurants are increasing the local demand, and<br />

AGRRA surveys show high fish diversity with no differences in population or abundance<br />

inside or outside the reserves. Grouper were abundant and relatively large in size. There<br />

is no evidence <strong>of</strong> over-fishing throughout the islands.<br />

ANTHROPOGENIC THREATS TO CORAL REEF BIODIVERSITY<br />

In the Bahamas, the predominant stresses to corals are sewage run<strong>of</strong>f and tourism<br />

impacts such as diver damage to corals and destruction <strong>of</strong> coastal habitats for hotel and<br />

marina development. San Salvador Island on the Great Bahama Bank is being damaged<br />

through sport diving, subsistence and sport fishing, and increased tourism and<br />

development. More than 4 million tourists visited the Bahamas in 2000 and tourism<br />

provides an estimated 60% <strong>of</strong> GDP and employs approximately 50% <strong>of</strong> the Bahamian<br />

workforce. Most <strong>of</strong> Bahamas’ population <strong>of</strong> 350,000 is in Nassau, Marsh Harbour and<br />

Freeport, predominantly associated with the tourist industry. This has resulted in rapid<br />

degradation <strong>of</strong> these coastal waters and coastal habitat destruction e.g. mangroves are<br />

<strong>of</strong>ten cleared for development. There is also over-exploitation <strong>of</strong> fishes, lobsters, conch<br />

and other target species.<br />

Bermuda has one <strong>of</strong> the highest population densities in the world e.g. 63,500 in 58km 2 .<br />

Virtually all available land has been developed and the coral reefs are under threat from<br />

coastal development, contaminated run-<strong>of</strong>f, sewage and industrial wastes. The inshore<br />

lagoons receive nutrients from agriculture and sewage run-<strong>of</strong>f and groundwater seepage.<br />

Sewage pollution is limited, however, by good flushing rates. The tourism industry<br />

accounts for about 28% <strong>of</strong> GDP, with the reefs a focus for diving tourists. There is some<br />

damage through poor diving practices, and anchor damage in the best locations.<br />

The resident population <strong>of</strong> the Cayman Islands is about 37,000, but total tourist arrivals<br />

exceed 1.4 million each year, accounting for about 70% <strong>of</strong> GDP. Rapid tourism growth is<br />

resulting in dredging <strong>of</strong> wetlands, but the 2 outer islands have escaped much <strong>of</strong> this, due<br />

to their remote location. Tourism-related developments have resulted in damage to the<br />

reefs including habitat destruction, increased suspended sediment loads from dredging<br />

and mangrove removal, sewage, oil pollution, and destruction by cruise ship anchors and<br />

anchor chains.<br />

In Cuba, about half <strong>of</strong> the shelf edge reefs are separated from the land by broad shallow<br />

lagoons and this protects the reefs and cays from most <strong>of</strong> the anthropogenic pressures.<br />

Threats to reefs <strong>of</strong> the southern archipelagos are currently low, however, tourism is<br />

growing rapidly with 1.8 million visitors in 2001, generating $US1.9 billion in gross<br />

revenues. While tourism expenditures generate considerable foreign exchange, the<br />

associated development is causing environmental damage along the coast, including<br />

prime habitats for endangered species. In addition to habitat destruction, there is<br />

increased pollution from sewage, agricultural run-<strong>of</strong>f and chemical contamination <strong>of</strong> reefs<br />

near high population centers (Cuba’s resident population is approximately 11.2 million).<br />
