Midwest? Where in the midwest is the pond; as north, central, or southern Illinois? This does make a difference as to how well your RES will survive. Generally the further south it is the better RES will thrive. Can we assume that Keystone buys their RES from AK rather than raise them their self? Southern raised RES are famous for not surviving northern midwest's hard winters. Do you have a strong reason to stock both RES and PS? Both have same food habits and niche habits thus the intraspecies competition will be an influence so each does not reach its full potential.

Common knowledge here about not stunting of RES is mostly due to experience and comments of Dr.Dave Willis. I tend to agree, however I have seen and know of ponds with RES to become stunted when their density becomes overly abundant due mostly to lack of predation. IMO just about ALL reproducing fish will stunt when predation is not adequate to maintain a fishery density 'balance'.

Wanting a forage or predator species and obtaining a forage species are completely two different things due mostly to availability. Some commonly discussed fish species here are scarce as 'chicken teeth'.
