If you've used a fish-friendly hook and it isn't in too deeply, unhooking a fish and releasing it is usually pretty straightforward. But sometimes, when you've got a really big, strong fish with a lot of fight in it, all the wild thrashing can make it frustratingly difficult to remove the hook. And the fish winds up injured. Canadian fishing expert Robin Pike recommends that you use this trick: Tail and invert the fish belly up in the water, which will disorient and pacify the fish for a few seconds. That should give you long enough to remove the hook and return it to its habitat.
