La baie de Corisco est une zone d'alimentation importante pour les tortues imbriquées (Eretmochelys imbricata), classés comme en danger critique à l'échelle mondiale. Après un certain nombre de «années perdues» en haute mer, les juvéniles recrutent pour les eaux littorales, loin de leurs plages natales. Zones rocheuses peu profondes convenables pour ce stade de développement se produisent uniquement dans la baie de Corisco, qui couvre les frontières du Gabon et de la Guinée équatoriale. Une meilleure compréhension de l'utilisation de l'habitat des tortues marines dans cette région est fondamental pour informer tous les efforts de conservation ou atténuation de l'impact ultérieures. En Novembre 2015, nous avons commencé baliser un petit échantillon de tortues imbriquées pour obtenir le premier oeil à leur utilisation de l'habitat marin de cette région.

*****************************************************

Corisco Bay hosts important foraging habitat for hawksbill turtles (Eretmochelys imbricata), classified as critically endangered globally. After a number of “lost years†in the high seas, juveniles recruit to nearshore waters, far from their natal beaches. Suitable shallow rocky areas for this developmental stage uniquely occur in Corisco Bay, which spans the borders of Gabon and Equatorial Guinea. A better understanding of habitat use of sea turtles in this region is fundamental to inform all subsequent conservation or impact mitigation efforts. In November 2015, we began satellite tagging a small sample of hawksbill turtles to get the first ever look at their use of the marine habitat of this region.
