Offshore Grand and Super Grand Slam Club An angler must capture three or four of the following species: dolphin, wahoo, billfish species, or any tuna species of the genus Thunnus (e.g., bluefin, yellowfin, bigeye, blackfin, longfin, albacore). Catching three of the four will earn an Offshore Grand Slam, and catching all four will qualify for an Offshore Super Grand Slam. Photos and/or witness information are required for each catch. Weighing the fish is not required for this, or any Slam Club. Anglers should limit the handling of all these species, especially billfish, to ensure a safe release.
