Another question that needs answering: How much of the feed is actually consumed by fish? Geese are a serious problem at times, and even turtles can take a toll. Feed that floats seems especially prone to these issues, as does increasing fish vulnerability to herons when the wind blows pellets toward shallow shore water.

Does night feeding help with this? Would more sinking pellets, which contain less fat & thus may help fish health & longevity, be a good choice? Interesting.
