The management board of the Con Dao National Park on June 28 announced a temporary suspension of swimming and coral viewing activities at several marine conservation areas from July 1 to September 30 in an effort to help the reef ecosystems naturally recover after experiencing bleaching.

More than 50% of the coral reefs in Malaysia's marine parks have been affected by mass bleaching caused by rising sea temperatures, the country's Department of Fisheries said in its announcement following a study conducted between April and June.
