Yellowfin tuna are another mainstay of the Bermuda fishery. These beasts show up each spring and fall. The largest yellowfin caught here weigh up to 200 pounds and put up quite a fight, so be ready to invest a little muscle to get these bad boys to the boat. Chumming for tuna, a favorite technique, always gathers a crowd. In May and June, and then again during the fall months of September and October, you’ll find boats anchored on the bank with a chum bag hanging over the side to attract a wide range of species, turning the water into a veritable aquarium. You can literally pick and choose which fish you want to catch and go after it.
