We don't do much ice fishing here in Texas. The perch you are referring to may not be the fish that we call perch. We have bluegill here which is a member of the sunfish family. I would think you catch them in much the same way. We use a very small cricket hook with a long shank. The long shank helps in removing the hook. We use night crawler worms.....they are long and fat so we just use about an inch of the worm at a time. You may even find that the perch will take whole kernel corn. Trout should hit the corn too. We set up with small float and a bobber-stoper. This way when we find the preferred depth, it will go to that depth each time.
