How do you fish on wow?

Answer 1

Fishbuddy should automatically switch on and off according to if you have a fishing pole equipped. If it is not doing this then there is something wrong and you should ask on the add-on authors site why it is not working properly.

Answer 2

First, you need to learn the Fishing skill (from any Fishing profession trainer) and buy a Fishing Pole (At the Fishing trainer or a Trade Goods vendor).

Find a source of water (any will do) and equip the fishing pole in your weapon slot. Open your profession trade skill window (default K) and find the button "Fishing". You can click it from the spellbook (or drag it to a skill bar and click from there) to cast your rod.

In the water, a fishing bobber will appear. When you mouse-over it, your cursor changes into a small hook icon. If you see the bobber bounce up and down (accompanied by a watery slushy noise) right-click the bobber with the hook icon to retrieve a fish.

Sometimes you will only catch grey items. This indicates that your skill was too low to catch anything useful. You will still improve your fishing skill, until you catch useful items.

Don't forget to return to the Fishing trainer when your fishing skill is maxed, to obtain the next profession level.
