I agree with Chris, My die off is pretty consistent with the first week of December, here in SW Oklahoma anyway.
Rainman or anyone else, I do often see a couple hundred to about 1000 dead in the 3-5 inch range every year. I thought this was great size for my bass to eat. Did they all die at once in a cold snap maybe before the bass got to eat them? Maybe I just had so many that the bass couldn't eat them fast enough? any theories?
Are there any studies about bass and tilapia die off?
