Ok so here is the plan for the SMB pond:

3 acres
WE 30
SMB 300
YP 450
RES 300
Paper shell crayfish 300
FH 10lbs
Grass shrimp?
Asian clams?

The goal of this pond would be two get trophy sized SMB, RES, and YP. With WE as a bonus fish. The Asian clam is already in missouri according to this map:

so I don't see any harm in having it in my local pond. however I don't know where I would be able to order any. the reason for the clam is to get trophy RES.
