hi there , the only method of feeding sturgeon i have had success with is to drop the food down a pipe directly to the pond bottom , this way the koi don't seem to notice until it's too late and the sturgeon have eaten it all .Don't worry too much about the koi they will stop eating when it's too cold ,but this pipe method might help in the temp change in late autumn . stephen walker
