Abstract

The presence of four sharks was documented in coastal waters of Antofagasta (Chile) using an unmanned aerial video camera. Fishers took advantage of this aggregation to catch and sold three adult broadnose sevengill sharksNotorynchus cepedianus. Species identity was determined by using thecox1 gene. One additional video was later recorded 3000 km south of Antofagasta, and shows a large female interacting with a salmon farming facility. Shallow water records ofN. cepedianuswere previously undocumented in Chilean waters, yet historically have provided an opportunistic event to fishers in Chile.
