That certainly fits everything I've read. My pond doesn't have much in the way of fusiform forage, so they don't have much choice.
As I mentioned, I really only got excited about the WE as predators after catching some really nice [to me] fish that had obviously thrived on BG for several years. It got me thinking that they might be more useful in BG control than I had previously considered.
I've tried to assist the WE by:
1]Feeding over dropoffs, rockpiles, etc. in deeper water.
2]Positioning feeder to throw parallel to shoreline that drops off steeply.
3]Only feeding at dawn and dusk.
Thanks to TJ for these ideas. I'm not sure at this point whether it's due to a healthy SMB population with many year classes represented, some larger WE, feeder changes, or all three, but there has been a really noticible reduction in BG numbers and subsequent increase in BG size over the past year. I'm definitely going to add more WE this fall.
