BigJoe's tip

Keep the shark in the water at the side of the boat, cut the trace close to the hook or use a long de-hooker, and let it swim off.

Catch and release

Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.

Regulations

Listed as Vulnerable (Critically Endangered in Europe) by the IUCN. Keeping porbeagle is banned in EU and UK waters; it is catch-and-release only, and other countries restrict it heavily. Every country sets its own rules: sea fishing licenses or registration in some countries, a national or regional license plus a local permit for fresh water, and minimum sizes everywhere. Check before you fish.

Conservation

Overfished nearly to collapse in the North Atlantic. Release every one.
