Catfish question

Cuz they're not smart enough to move up in the water column to find oxygen?.....look at the massive walleye kill they had a cumberland last year when the oxygen level got low

I didn't know about the large walleye kill, I catch a few every spring. but this spring, I had the best year for walleye. I've ever had. I thought the walleye in cumberland were doing great.
