nice info, Lux :-)

Update: As of latest patch 1.22 Young Indigo Herring is the same as Indigo Herring. The favored bait is Floating Minnow / Depth: +3 / School of Fish Only / Grade 5 by Camp Bard Knoll. Jig is Middle. Also, Navigator's Ear same position. You should be able to yield 5-10 Fishes 70% of the time in one pull. (Assuming you have good gear on). Average about 200+ fishes in 1 hour 30 minutes or less. (Including HQ). The Fish are traded for Points and Ranking for Hamlet Defense plus Anima recovery. The Navigator' ear can also be used in Alchemy 45+ with a few more cheap ingridients to make potions for Hamlet defence to turn in for more points.

Note: there will be 4 spots not more then 200 yalms apart from each other on west of camp where the schools are located. Use your FSH abilities to find grade 5 School.

I can fish them up with just my spoon lure :)
Sometime i got like 10 fish for 1 reel.
Yield for anima trading 10 fishes = 4 animas
