Vários chernes juvenis, Polyprion americanus (Schneider. 1801) foram capturados à superfície da água e marcados em vários locais próximos das ilhas do Grupo Central dos Açores. Um dos exemplares foi recapturado 3 meses depois ter sido marcado, a 217 km do local onde tinha sido libertado e a uma profundidade de 254 m. A recaptura deste espécime indica que o cherne passa para uma vida demersal quando atinge um comprimento total de cerca de 50 cm.
ABSTRACT: Pelagic juvenile wreckfish, Polyprion americanus (Schneider, 1801) were tagged in the surface waters around the Central Group of the Azores. One wreckfish was recaptured three months after tagging, and 217 km from its release point. It had settled to the bottom in 254 m of water. The recapture of this specimen suggests that wreckfish take up a demersal life at a total length of about 50 cm.
