Big Swordfish
From Runescape Guides & Runescape Tips
A Big swordfish is a swordfish that is randomly caught by members who are fishing for regular swordfish. You can high alchemy the swordfish for 3000 or cook it. If you cook it, it will turn into a regular cooked swordfish or a regular burnt swordfish. The most common use for a BiG Swordfish is to hang it on the wall of a player owned house. You can have the swordfish stuffed at the Taxidermist for 2500. Then, you can mount it on the wall, if you have 56 construction. Makes a nice momento to keep. =D
