Air pressure and water and air temperature have a massive impact in the way (confidence) and amount the feed. I would like to think that this is in some way similar to captive kept koi. If all things are right could we possibly feed up to 20% body weight a day?

Do I understand that one blue carp eats 10 kg (22 lbs.) of bait daily, or the entire population in the lake gets fed 10kg daily?
I think that if our tanks were big enough for proper koi exercise, and filters were big enough to hold water steady, one could possibly feed 20% body weight.
I am going to try 10 % bw feeding due to the fact my captive koi seem to have hit a wall in size development. Air temp has been in the 80's F. The demand feeder also makes allot of sense. 100 lb blue carp...that is huge, be careful Sharpey! Do you tie a rope around your waste and attach it to a tree when you go for the big ones?
