Abstract: A total of 183 C. mydas individuals were caught foraging in the Grand Lagon Sud (GLS) of New Caledonia. This area was added to the World Heritage list in 2008 but turtles are still being hunted for traditional use in that area. C. mydas were captured in three different areas by the rodeo method with the knowledge of the traditional landowners, so females as well as males and juveniles could be sampled.. All individuals were tagged and measured before being released where they were caught. No adults were captured and only 5 sub-adults were encountered. No significant difference in the size Curved Carapace Length (CCL) was found between the individuals caught during nesting season when compared to the ones caught outside nesting season but adults were captured during the same period for traditional use. There results show that recruitment is happening for C. mydas in New Caledonia but also raise concerns about the number of adults in the area.
