I went fishing for these for Grand Company provisioning missions. I used honey worm as I wasn't high enough level to use spinner. I first tried Middle Hathoeva River (South Shroud) but after about 15 casts and not a single one I decided to try Rootslake (South Shroud). My gear was all HQ, although a bit outdated (item level 32). Gathering 167 Perception 137. I went from level 37 to 40, and again this is all on honey worm at Rootslake. I was going to go through three stacks of worms but the exp just didn't seem that great and I wasn't catching as many HQ Armored Pleco as I would have liked. I was hoping for at least 9 or 12 but I stopped at 6. Out of 201 catches my results were as follows;
Bone Crayfish (lvl 5) NQ 20 (9.95%) HQ 5 (2.49%)
Climbing Perch (lvl 27) NQ 30 (14.92%) HQ 7 (3.48%)
Armored Pleco (lvl 37) NQ 70 (34.83%) HQ 6 (2.99%)
Root Skipper (lvl 33) NQ 23 (11.44%) HQ 11 (5.47%)
Mitten Crab (lvl 34) NQ 23 (11.44%) HQ 6 (2.99%)
