The only reason not to collect in cold weather is that if you fall, you
will be very cold very quick and your water-filled waders might take you
downstream. So, if you need a collecting buddy, let me know. I need an
excuse to get out! Maybe we could make it a mini NANFA outing and invite
some of these other guys. I think I have made that kind of temp change
before. Sunfish will tolerate it better than darters, minnows or sculpins.
You need to maintain heavy aeration. I use a powerhead with a venturi
aerator. But that also adds heat. You just have to expect that the fish
are going to be stressed for a week or so until their bodies adjust to the
warm water. Get extras, because some will die. If it's in the basement,
open a window and keep things cooler for a while.
