Your LMB likely are exhausting their food chain hammering YP and BG in that size range [2-6"]. Good news is your adult YP and BG should be pretty solid fish that have grown beyond predation range due to lack of competition for forage. Bad news is you may have a bottleneck of skinny, hungry [low WR] LMB.

Depending on your goals this is good or bad. If you want more trophy LMB reduce their population - take out all skinny or bottlenecked LMB 12-15" you can catch. Leave healthy LMB in the fishery. Also consider harvesting any CC you catch. Both these actions will help take the pressure off your BG and YP populations.

If you don't mind high population of LMB and want a trophy BG/YP pond you can keep density of predators [CC and LMB] high and continue to supplementally stock adult YP annually.

What are your goals?

Many men go fishing all of their lives without knowing that it is not fish they are after. ~ Henry David Thoreau
