Seychelles' Coral Marine Environment at Risk

The coral reefs of Seychelles are in grave danger due to the damage sustained during last year's warm El Niño and the general effect of climate change, says a local marine biologist.

Jude Bijoux told SNA that, “The current live coral cover in sites that have been monitored is now approximately 3 to 5 percent and very much at risk due to the warming effect of the climate change."

The level of coral bleaching currently is similar to the bleaching catastrophe which happened in 1998, where up to 97 percent of corals in some areas bleached and caused many reefs around the islands to collapse into rubble.

Bleached coral continues to live, but without its colourful symbiotic algae it loses most of its food source and becomes extremely vulnerable to disease, predators and invasive organisms like seaweed and sponges. If the water temperature remains high, the coral will die.
