Ok when u start off and u liked fishing in runescape. all u know is your a total noob! most likely your like fishing shrimp is way too long. so hear is an idea go to the swamp area go see the fishing guy. so ask about crayfish cage fishing. after u get the cage run behind church u will know it when u see it don't have any thing accept the crayfish cage.next after u get 27 crayfish or the rest of your inventory samething.go see the cooking guy go use his range cuz in the castle he doesn't use it unless u finish a quest.now cook them this way u get cooking up to.so after that do over again tell about 20 fishing.then fly fish tell u can harpoonthen harpoon tell u get 5 lvls above lobster pot fishing.then harpoon again at 60 cuz u can harpoon swordfish.ps don't cook lobbies or swordies cuz then they won't sell at the grand exchange.
