Although there is a lot of very useful information on bait and temperatures on the forum, I cannot find the answer to this specific question.
When there is a sudden and unexpected change in temperature, should you change the bait? For example, it is July and the fish are on rice, as normal, and you know that rice still has some life left in it. But the temperature drops significantly for a few days, into the "oats range", before rising back to its normal level. Should you switch back to oats during the temporary temperature drop or continue with rice?
