Outdoor - My experience is that LMB will not grow as large solely on YP as forage compared to LMB with BG for forage. Reasons have a lot to do with Theo's answer.

1. Minnows from stream that spawned in your pond will not leave the pond, at least most of them will not leave. The species of minnows from the swamp stream could be any of several species including sunfish. LMB (& YP) will probably do a good job of controlling or eventually eliminating the minnows providing they are not carp. If carp you may have somewhat of a problem. Unless you know what species of fish spawned in your pond, I would stock LMB this fall to make sure the hatchling fish do not get out of control or too large for predation. If you want BG find a local pond with a good population of true BG (not hybrids or green sunfish) and add 8-20 juveniles (4"-6")or adults per 0.5 acre this fall or next spring.
