How to determine when fish are UP

[bereabasser]

When the water temps start hitting the 40 degree mark the pigs start moving. I've had double limit days with a buddy throwing cranks in 43 degree water.

so since the water temp on dale right now is 45 it needs to come down 2 more degrees for the bigguns to start moving?I doubt any fish will be up roaming around in 43 degree water temps,maybe 53 or 63?
