Decades of harvesting and habitat degradation have led to a drastic decline in the sea turtle population in the last century. Manr, foraging grounds and nesting sites have been degraded or have disappearedas a result of human activities.Nowadays, there are onll' a few nesting sitesand evenfewer foraging grounds for seaturtles in China. Fishery'bycatch is also believed to have been a major cause of sea turtle ntortality' in recent years. There is an urgent need for more efforts to be focused on the conservation of sea turtles in the region. However, limited information is available, which has impeded the formulation of effective conservation lneasures. The goal of this paper is to provide an overvieu' on the current population and conservation status of sea turtles, as well as recommendationsfor their effective management in China.
