Assessing the genetic composition and origin of green turtle populations, which are migratory marine species, is known to be an effective way to increase their conservation efficiency. This study showed the genetic composition and origin of the green turtle population found in Korea and evaluated the genetic composition, diversity, and origin of the Korean feeding population. Genetic analysis was performed using partial mitochondrial control region (CR) sequences, and mixed stock analysis (MSA) was performed to confirm the origin. A total of 10 CR haplotypes were identified in Korean feeding population and all of them previously reported in the green turtle breeding population in Japan. In the haplotype network analysis, six haplotypes were grouped with the Japan clade, three haplotypes were grouped with the Indo-Pacific clade, and one haplotype was grouped with the Central South Pacific clade. In the MSA results, the Korean feeding population is largely contributed by the rookeries in Ogasawara Island (OGA) and Central Ryukyu Island (CRI). In regard to season, maturity, and specific feeding region groups, individuals found in summer and the Jeju feeding region had the highest contribution of OGA, and found in fall and the East Sea feeding region had the highest contribution of CRI. The results of analysis by maturity group showed no significant differences. Our results showed that the origin of Korean green sea turtle feeding population is mainly from Japan's MU, and have genetic orgin from Japan, Indo-Pacific, and Central South Pacific clades. Population conservation efforts in Korea will not only affect the nearby Japanese breeding population, but also affect Indo-Pacific region. International collaboration with Japan as well as the countries in Northeast Asia and Southeast Asia must develop for green turtle conservation.
