Canyoncreek, you might be on to something with the artificially heated "refuge area".
I nominate you to build one, try it out, and report back to us on how it works.
Esshup has talked about how they will go to shallow water that the sun has warmed where he has snagged them.
Where most of the ones I captured are in a 1/10th acre sediment pond, have thought about just going out with the cast net and trying to canvass the bottom (basically trying pot luck). That is the pond where we mostly saw the white tilapia feeding this summer (and that I have retrieved only one of the whites) and the pond is small enough I might just get lucky.
Think I will go out and try that right now! Mostly stopped raining............finally.
