Something in the Water

Starting the quest
To start off you will need 51 fishing, a fishing rod and bait. Speak to Gerrant in Gerrant's Fishy Business just South of Grum's Gold Exchange in Port Sarim. Ask him for a quest (which requires 51 fishing for the option to appear). The conversation will go like this:
 * You: I am a Bold adventure and seeks for a quest!
 * Gerrant: Do you actually think a fisher store owner like me have anything interesting going in our lives?
 * You: Umm...I guess so.
 * Gerrant: Adventurer you are both wise and unexpectful
