Each year, during the full moons of spring, whale sharks gather in Gladden Spit, a remote reef located 30 miles off the coast of Belize. Gladden Spit is an important reproduction site for more than 35 species of fish who aggregate there to spawn. Whale sharks are attracted by the huge cloud of gametes released into the water. Not so long ago the site was endangered due to uncontrolled fishing. A local conservation organization, S.E.A was chosen to manage the area and protect it. One of their initiatives is the promotion of sustainable tourism based on whale sharks.
