‘I’m happy we’re not killing them any more’: Ireland’s last basking shark hunter on the return of the giants

For 30 years, Brian McNeill hunted the world's second-biggest fish from small boats off the wild west coast of Ireland. Now the species has made a recovery so rapid it has astounded scientists

The ambush was simple. A spotter on a hill would scan the sea and when he saw the big black fins approach, he would shout down to the boatmen. They would ready their nets and quickly row out to the kill zone.

When a shark got tangled in the mesh, Brian McNeill would wait a minute or two while it struggled, then steady himself and raise his harpoon. This was the crucial moment. The creature would be diving and thrashing, desperate to escape. If the blade hit the gills blood would spurt, clouding the water. The trick was to hit a small spot between the vertebrae.
