There are other nice things one can get from fishing. Fishing schools will yield fish of a certain type, but this is also where one will find Crystallized Water, Northrend's version of the mote of water. Combine ten to get one Eternal Water. The respawn rate on these schools is much faster than was seen in The Burning Crusade.

There are a number of achievements for fishing up assorted coins from Dalaran's Eventide fountain. A new mini-pet, a Giant Rat can be fished up from the waters of the Underbelly in Dalaran. Here you can also fish up a Rusty Prison Key, which can be used to open a treasure chest, which yields rare quality weapons and armor or other rewards.
