If the temp is warm at least 4 days in a row say lower to upper 60's and the water is warming up and some fish have begun to spawn and then a cold front comes through the next night...do the bass stay in there stage or retreat..??

aprreciate replys ???

Depends if its just the males up then they might disappear. If the females are up and locked on tight then its 50/50

either way the fish will be close

My observations tell me that the majority will leave if the water temp declines by 4 degrees or more. Last year after a strong cold front in my private laboratory pond, of 8 pairs (or trios in two cases) of bedding bass, just one female stayed locked on.  She relented after about 60 hours of cool down, and left the nest. I don't think she laid her eggs before she vanished either. Never did see her again return to that bed, nor did I see any fry. I think that cool front really hurt a successful spawn. I saw very few fry in '04 after a great '03.

so it would have to be a drassitic change pretty much....?
