It's been my experience that unless a pond is heavily vegetated, chain pickerel(CP) don't compete well with LMB in smaller ponds. They are narrow and easily swallowed by bass.

They can take up some of the biomass that bass would otherwise take up, so that should be kept in mind. I do believe they can be utilized in controlling bass numbers, so they do not get out of control. They are less effective at controlling BG numbers.
