The problem with other anglers is not them catching fish, it is mostly them preventing me from moving around after schools fishing the way I want, especially if I have gone out of my way to get away from people so i can drill like a madman.
some of you guys need to learn how to catch fish without telegraphing it. keep rod tips down, slide fish on ice and then toss directly into a bucket if keeping. I have fished in my flip over for only reason to keep people away from me. I have had guys setup next to me not catching a single thing and assumed I was not the entire time, only show them a limit when I leave. Fishing ninja style!
Other tips - fish at night, fish first or late ice when ATV's are not out, those lazy fishermen will not walk that far to crowd you.
If you are high sticking panfish and swinging them through air into a giant pile to flop around, don't be surprised when you attract sea gulls.
