Prince Edward Island is the bluefin tuna capital of the world, and the fish grow to extraordinary sizes in the Atlantic here, averaging 700 pounds and nine feet in length. In scenic Tignish, on the northeastern coast of Prince Edward Island, you can board a charter boat and learn to fish for mackerel, another popular fish. While it’s possible to simply cast a line and fish for mackerel from many piers, you’ll head off in search of larger schools on a charter tour. The much smaller mackerel—the largest are around 20 inches—provide meals for the pods of tuna that will swim right under your boat as you hand-feed them your fresh catch. An added bonus: opportunities to spot minke whales and watch amazing gannets dive into the sea looking for their own fishy meals.
