Due to the 2004 Indian Ocean earthquake, lagoon fishery was adversely affected, with many fishing communities losing all means of livelihood until the middle of April 2005, as the loss of lives, homes and boats prevented them from going fishing in the sea and the lagoon. They subsisted on relief supplies provided by the government and other agencies. Many people in fish related trades were also affected. However, a beneficial effect of the tsunami has been the widening of the opening to the lagoon.
