| 内容記述 | Loggerhead turtles (Caretta caretta) in the North Pacific Ocean are primarily born in the southern coast of the Japanese Archipelago. After a developmental period of several years in Central and East Pacific Oceans, they re-migrate to Japanese waters at a larger juvenile stage. However, the exact duration until re-migrating to Japanese waters is not known because of methodological limitations of current age estimation among wild sea turtles. On 27 August 2018, a juvenile loggerhead turtle (straight carapace length: 60.8 cm, body mass: 35.0 kg) with a passive integrated transponder (PIT) tag was incidentally captured by a set net at the Sanriku Coast, Northeastern Japan (39°22′21″N, 141°58′41″E). The PIT tag number revealed that it is a 10-year old turtle born in Yakushima Island (30°24′21″N, 130°25′58″E) in 2008. Total 1,095 loggerhead hatchlings with PIT tags were released from Yakushima Island in 2008. To the best of our knowledge, this is the first record of a known-age and non-head started loggerhead turtle in the North Pacific population. The tagged loggerhead turtle provides important knowledge about the pelagic stage duration of this species in the North Pacific population. | |||||
