I used to do the Qufim Ice Pond with Sinking Minnow. Only fish you will hook is Black Sole. However, even with Fishing Apron, bite rate is really low (about 20-25% over course of day). Fishing up 200 takes about 8+ hours. Really not a fun experience. Since Sole prices shot to sh*t on Hades, I just fish 200 Dil/Merc/Ahta in Talacca in half the time. Much better for your health if you are the kind of fisher that does it every day. About 30-40% of your catches will be Dil (eastern Black Sole) anyways.
