New non-invasive methods for short-term electronic tagging of pelagic sharks and rays
Biologging technology has provided scientists with unprecedented tools to investigate the ecology and behaviour of marine animals, but tag deployment and attachment methods have lagged behind.

Biologging technology has provided scientists with unprecedented tools to investigate the ecology and behaviour of marine animals, but tag deployment and attachment methods have lagged behind. Electronic tagging of elasmobranchs still essentially involves implanting anchors or drilling the fins of restrained animals.

The attachment of a modified fin clamp and a harness systems were tested on 12 blue sharks and four devil rays in the Azores, mid-north Atlantic.
