Fisheries and aquaculture (plenty of fish, shrimp, lobster, clams, pearls and seaweed) are undergoing constant development. The population of the coastal waters of the Indo– Pacific Equatorial zone are linked to significant productivity as determined by the study of coral reefs ecosystems. Clear turquoise water ebbs and flows at the edge of a tropical shore. Beneath the water′s surface exists a breathtaking underwater world? Home to a diversity of colorful exotic fish, corals, and countless other marine creatures – this is the coral reef. Oceans, seas and fresh water cover more than seventy percent of the earth′s surface. While coral reefs take up only a very small fraction of the ocean (less than onetenth of a percent), they are home to an astonishing variety of animals and plants. Coral reefs have very high biological diversity (biodiversity) – approximately 93,000 species of plants and animals have already been identified in coral reefs, and scientists predict that there may be over three million. Coral reefs are the primary source of food and income for millions of people. They produce valuable chemical compounds for medicines, and provide natural wave barriers that protect beaches and coastlines from storms and floods.
