They eat almost all of the pellets until it drifts up to the shoreline. Been feeding since I stocked them last September. I'm guessing that feeder is throwing about one to one & a half cups in a second. I don't know if the Sweeney spin plate distance is adjustable. I was just wondering if I'm feeding too much since they are still eating an hour or so later. They look healthy and have a big belly.
The way the feeder is set at the pond, does the prevailing wind push the pellets back to the shore or across the pond? If the feeder is throwing into the wind constantly, see about moving it so the feed drifts across the pond. The feed (if you are feeding smaller forage fish) should be thrown in water that is 3''-5' deep so the forage fish feel safer. Not that you have large predators now in the pond.
They might not be getting a chance to eat it before it is blown to shallow water. In my mature pond, I throw so the feed goes across a shallow area but some of the feed is thrown over deeper water. Smaller fish feed in the shallows and the predators (HSB) blow up on the feed in deeper water. The wind usually will blow it all out to deeper water and before it's half way across the pond it's all gone.
As your pond matures and the fish get bigger they will consume more of the food faster. You have the feeder set on the lowest setting now, I wouldn't worry about it.
