Fishermen don't necessarily catch them at sea and bring them closer to shore. Sharks can easily navigate to shallow water on their own. Last time I was at Holden (about 2 weeks ago) I saw a fisherman at the Point (who was standing on a sand bar at low tide) catch a three-foot shark (sand shark most likely). No boat/ship necessary. Like the surfer said, it's the ocean - not a pool or lake. It's part of the experience.
