Fishing Guide - ARR?

[LaxusLanverLais]

So, I am looking for a specific fish at a specific location, so please bare with me a bit.

River Sphinx, supposedly located in a "fishing hole" South of Thousand Maws, Now, I spent a ton of time there last night and never found a hole. When they say hole do they mean an actual hole", or does it stand for something else, like the start/end of a river, etc. I just got Gulleye, and am still new to fishing (even from 11), so the terminology and action are lost a bit on me. Been kind of winging it so far.

Any advice or help would be great, also I can safely assume no one has put together a comprehensive, lower level guide that lists out specific locations (I mean actual coordinates), fish level, and bait used to catch those fish. If so, please forgive me, and give me the link, please?

Thank you all for reading this and any replies you have.

Edit:
I have found some links I like, some from here, and from other places. Still need information on "holes" though. You can forget the rest if you like
