Snrub, RES are easy to catch when they start spawning. Just like BG. They start a little earlier than BG like late April, around here. I catch them the same way I fish for spawning BG. Very little or no weight just enough to cast, and a #6 or #8 hook with a small piece of nightcrawler. Put it on their beds. If you don't get a hit immediately, move it very slowly. If the pond is very clear use a 4 or 6 lb flouro leader.
And funny thing is, I have caught them in the same spot that I am catching BGs in.
