A big swordfish is an abnormally large swordfish caught while fishing at any cage/harpoon fishing spot, it is obtainable by both barbarian fishing and by normally fishing swordfish using a harpoon. Since players can only get it while fishing for swordfish, it requires 50 Fishing to obtain. It is a very rare catch (1/2500).
To stuff the big swordfish, players must take it to the Taxidermist in Canifis. She will charge the player 2,500 coins and turn it into a stuffed swordfish. Once it is stuffed, players can mount it in their Skill Hall at 56 Construction, using a stuffed swordfish and 2 teak planks, producing a mounted swordfish.
- Previously, if a player attempted to cook a big swordfish they would get the message "You don't have any more swordfish to cook." Now, players can cook big swordfish just like normal swordfish (the player will receive the normal XP and will receive a cooked swordfish, if they don't burn it).
- Whenever you catch a big swordfish you will receive the message: "You catch an enormous swordfish!"
