I generally feed once or twice a day -- early morning and/or late evening. Since the pond is so small, I throw the pellets out by hand. I would estimate that I feed on average a pound per day (a 50 pound bag of feed may last almost 2 months).
This would equate to 2.5 pounds per acre per day, which is pretty significant feeding from what I've read.
But, as I mentioned earlier, it seems that most of the feeding is done by really small bluegill... which is puzzling if in fact there are large bluegill in the pond. I would think the larger fish would wear the feed out.
