Zach a very intresting question...I am so glad you started this thread, although I am afraid very few people will respond. I tell you, you will ask about diffrent species 'if they will eat pellets' and you always get "Oh Yehaa" "sure they eat pellets" I get this from every fish Dealer on just about every species execept Redear.
My guess is, Blues only eat pellets when they absolutly have to. These guys, I don't care what people tell you, are as predatious as Bass or even Flatheads for that matter. From what I read, you have a TON of forage in you LAKE, in the form of shad and other bait fish...correct?? If so blues are going to eat them, and not the pellets.
The first pond I had two years ago had blues for about a year when I stocked them...they NEVER eat the feed, but the channles tore it up.
