This post used to be on my blog (http://www.aroundtheglobe.biz).
I decided to move it to Steemit for better hosting, sorry for the invonvenience, please update your links!

In this post you will find the list of fishes of the different zones, as well as maps indicating where to get them in these zones.
I did not try to map every single fishing hole on the map, but rather to provide at least a few fishing holes of each type of water on each map.

Map conventions and baits:

As there is no text coloration on steemit, blue fish will be in italic

As you probably know, the type of bait is critical for your rate of success while fishing. Read the maps as follow for optimal results:

It is an Ocean, use Worms or Chubs

It is a Lake, use Guts or Minnows

It is a River, use Insect Parts or Shads

It is Foul Water, use Crawlers or Fish Roe

I didn't throw a line here, plugin registered the hole, but I don't know what it is: use your intuition!

Tools

Credits deserved very much here, to the tools that made this tutorial possible:

• Rare Fish Tracker, By Katkat42, which make it easy to track what you had/need in each zone.
• Votan's Fisherman, By Votan, which allowed the creation of the maps (And his filetting addon that saved my mouse)

Zones:

The first three zones are islands, with only ocean, just walk around and you'll find many more holes than on my maps!

  Fishing in Cyro was the worst part of this achievement, mostly because as a member of the Ebonheart Pact, most fishing holes where in enemy territory. As the map tries to show:
• Foul waters are in the middle, near imperial city (I got all fishes from the same one)

• Rivers and Lakes are plentiful near Drakelowe keep.

That's all folks, I hope this guide helped you well! - Please upvote it if it did ;)

Update, I completely forgot to mention that as Zeni disabled OpenGL support, effectively removing Linux support. There is some marketing bullshit somewhere around there, as technically the game still runs on MAC... they just messed up somewhere and don't know how to fix, so they removed the support from the config. Anyway, I'm out of it for that reason: byebye ESO
