A Raw swordfish is a fish that can be caught with level 50 Fishing or higher with a harpoon, granting 100 experience per catch. Fishing swordfish takes a lot longer because tuna is also caught with it. The amount of tuna caught is significantly higher than the number of swordfish caught while fishing with a level under 60. Above 60, the amounts get closer, but a player will always catch more tuna than swordfish while harpoon fishing.
Cooking a Raw swordfish will yield a Swordfish if the player has at least level 45 Cooking. It is impossible to burn swordfish after level 86 Cooking or 81 with Cooking gauntlets.
