Hi fellow DoLers!
First off, I'd like to thank Truvy for her contributions and I'm sure many fishermen and women have found Truvy's Isle of Umbra resource to be absolutely fantastic, as did I.
I've been doing some exploring as well and testing and I found another location which has given me great results as well.
In Gridania, there is grade 10 body of water at Murmur Rills (9,36), which is southwest of Camp Crimson Bark. This whole area is fishable, as it is surrounded by water. The area I fish at is (10,35) or (11,35) which is a little stream of water rushing down. I'm fairly certain you can fish anywhere around Murmur Rills and still have the same results, but for me I really enjoy the fast stream of water when I fish because it makes me feel like a grizzly bear snatching fish out of water. The only mobs around here are goblins and they do not aggro. Very safe near the aetherial node as well. However, getting here from Crimson Bark is a bit tough because of the mobs that aggro (diremites and efts), but I had quickstride so I was able to blast through them easily.
Anyways, the lure that I use is wildfowl flies and and I set the depth to -4 to catch striped gobies. I get the "fish seem to be biting on wildfowl flies" and the "something big hits your line!" messages just as often I as I did at Isles of Umbra with sinking minnows. With fatigue and surplus, I was getting 270-290 per catch at rank 43. I will note my SP/hr here once my surplus resets in about two days.
The reason why I like this camp a lot is because sinking minnows are never sold at the market wards on my server, whereas wildfowl flies are usually available or much easier crafted than the minnows. Also, the Isles of Umbra is full of fish botters so I wanted to stay as far away from them as I could. Murmur Rills is usually all mine when I fish there.
Please give it a try and let me know how it goes! Again, thanks Truvy for inspiring me to explore more, and the wonderful contributions you have made to this site.

UPDATE
With surplus and fatigue gone, at rank 44 I was able to pull in 14k/hr here with Sweat of Brow. Good luck guys!
