Antigua and Barbuda is home to 32 species of stony corals,
-
In 2006, 32 species of stony corals covered 2–19% of the reef benthos at 2-10m but cover on deep reefs was less than 3%.
-
Although only 1% of coral colonies showed signs of disease, more that 20% of shallow Montastraea colonies displayed yellow blotch disease. The 2005 bleaching event resulted in average coral cover being reduced from 16% to 7% by 2007

Fish consumption is high and commercial fishing accounts for 1.48% of GDP (2003) and employs over 1,000 people (2% of population). Catch includes conch, lobster and finfish and total export in 2001 was 368 metric tonnes. There are 9 export facilities in Antigua and 2 in Barbuda (2004). Fisheries Regulations, revised in 2013, limit the fishing of certain protected species like lobsters, marine turtles, conch and parrotfish. Fishing these species requires special permits for spear guns and beach seine nets that have minimum mesh sizes.

Famous for its 365 beaches ‘one for every day of the year’, tourism dominates the economy and accounts for over half of the nation's GDP. Tourism in Antigua and Barbuda accounted for over 70% of GDP in 2002 and was valued at $528 million. Boating tourism is particularly popular, due to the numerous sheltered bays and inlets ideally suited to fishing, snorkeling and SCUBA diving.

Coral reefs and their associated resources are essential to the economic sustainability and growth of Antigua and Barbuda, which is said to have the highest reef dependence in the Caribbean.
-
Key environmental threats include hurricanes and coral bleaching events. Hurricanes Hugo (1989), Luis and Marilyn (1995) caused extensive damage to reefs in the south and southeast.
-
ll reefs are threatened by human activities and key threats include overfishing and recreational diving. 70% of reefs are threatened by coastal development and 30% by marine based pollution and sedimentation, resulting in turbid coastal waters and elevated algal cove

According to climate modelling, reefs in the area will experience thermal stress severe enough to cause bleaching every year after 2040. Ocean acidification is expected to cause declines in coral calcification by 2040 of approximately 10%.

Six Marine Parks have been established, encompassing 13% of the total reef area. These include: Diamond Reef Marine Park; Palaster Reef Marine Park (both gazetted in 1973); the Cades Bay Marine Park (gazetted in 1999); and the Codrington Lagoon and the North Sound (gazetted in 2005). However, there is little active management of these reserves
