Yes, you should. Your LMB are failing to thrive. They need food that is 1/4 to 1/3 their body size. It's a matter of calories received vs energy expended. Catch and release works on public lakes but not in enclosed ecosystems like a private pond. The culling/management of bass in a one acre pond never stops.

The crappie could be putting undue pressure on the size of forage that the LMB need. They spawn earlier than bass, have a hinged jaw like a bass and put a lot of pressure on the bass and the forage base when they emerge. They also spawn erratically so can't be depended on for management. Lusk tells about a 70 or so acre private lake in NE Texas. It was over loaded with small crappie. When analyzed, there were a lot of 7 year old, 4 inch crappie, with not enough predators to control them. They were no doubt eating the young of year predators. In other words, a typical out of balance ecosystem.

You need a max of 100 lbs of predators per acre. OK, what is really a predator? A large BG that eats a fingerling bass can be considered a predator but this thought kinda skews the concept.

Don't feel bad about this. Your situation is very typical in an unmanaged pond.

Clobber the crappie, reduce bass until the RW is back in control.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
