Bangladesh, located on the northern side of the Bay of Bengal in mainland Asia, supports five species of sea turtles in its territorial waters, including the olive ridley turtle, green turtle, hawksbill turtle, loggerhead turtle and leatherback turtle. The total coastline of Bangladesh measures 710 kilometres approximately. Not all the coastline is suitable for nesting, as sandy beaches are available in sections along the mainland coast. Apart from the mainland coast, there are numerous offshore islands whose sandy beaches ideal for sea turtle nesting. Olive ridleys, green turtles are common while hawksbills are rare. There was an unconfirmed record of loggerhead. Leatherback turtles are seldom encountered and with no known records of nesting, in Bangladesh. sea turtles have never been prioritized in any agenda for research or conservation since Bangladesh gained independence in 1971. Like other areas in the tropical world sea turtle population was far better along the coast of Bangladesh while the nesting rookeries were widespread. During the last 3 decades serious degradation and multifold threats in offshore and inshore areas turtle nesting is now confined only some undisturbed sandy beaches out of 710 entire coastlines. Areas identified by the researchers are St. Martin Island, Sahporirdwip to Cox?s Bazar long sandy beach of Sahporirdwip Teknaf Bordal Kochopia, Inani Monkhali Sonadia Island, Kutubdia Island, Sandwip, Egg Island, Mandarbaria, Dubla Island and sandy beaches of Sundarban area. The nesting season in Bangladesh begins in late monsoon to early winter each year with olive ridley first and then greens in late up to rainy season. While there is estimation to have five traversing species in our marine territorial waters only three species have been recorded to nest Including Hawksbill turtle in St. Martin Island and other nesting rookery only supported Olive ridley and Green turtle in some areas. The nesting population is extremely small comparing the size of rookeries resulted by the indiscriminate loss of nesting ground through development & disturbance, mortality of population stock in the sea by commercial shrimp trawl net and gill-netters.
