So, I finally got my fisher to 60 (all geared in my nice ironworks gathering gear)

And I cannot figure the fishing aetherial system.


I tried going back like 10 pages in the section, nothing.
Looked on the internet, there is barely anything, and no real guides.

Why is this? I know you fishers know how to get that sweet sweet seaborne.
Please help a Roe out!

PS-I gather land and leaf all the time btw so I know how it work with mining botany. but this...
