It an untradeable item. The only other way to get to the dragons is to have 70 agillity. And as I don't have that and don't want to run near a blue dragon it not the best idea
Why do you want to fish pike? Shilo would be best to bank, or you can use the spot west of the fishing guild and sell the pike to Rasolo who hangs out near there. Thought it'd be quicker xp than Lobsters, What would be better doing bait fishing or fly fishing?
