After reading the Guide to Fishing Tamriel, I found the content lacking sufficient details to satisfy my scholarly curiosity. I wanted more details and it set out to answer my many unanswered questions.
The fish do you no good in the water.
This guide covers fishing in a very comprehensive and organized manner. Fishing results in special achievements (including one of the rarest titles in the game), crafting raw material (including the legendary ingredient for crafting experience potions), and rare sellable fish. The legendary ingredient, Perfect Roe, is currently fetching a high price and harvesting it is a lucrative activity. There are four types of water fish can be found and particular bait must be used at the right location to obtain the best results. Fishing parties looking for rare fish should limit their group to 4 or 5 people. The table below lists the water types and their respective baits. Several tools have been created to make fishing a lot easier.
