Pelagic longline gear has been deployed in collaboration with French commercial longline vessels to study underwater capture/escapement processes of megafauna. Underwater cameras attached to the branch lines, 1-2 metres above the hook, allowed the observation of a pod of 3 short-beaked dolphins. Their echolocation clicks were also recorded by the Spydro® underwater camera. No interaction with the baited hook was observed.

The Gen&Rec project (“Distribution and behaviour of swordfish spawners and juveniles in the vicinity of Corsica”) was an IFREMER programme financed by the European Union (European Maritime and Fisheries Fund – EMFF) and by the fishing industry (France Filière Pêche - FFP), conducted in close collaboration with French swordfish longline fishers.
