Fishing allows a character to hone their hunting skills and enables you to fish for fish and other things lurking in the watery depths. You can consume some items in their raw form or cook (if you've trained in cooking) for increased benefits. The food can be used by hunters for their pets and you can even fish out reagents useful to alchemy and chests with goodies hidden inside. - Worldofwar.net
