Thanks a lot CGBS! I will see if I can find a souce of Mississippi grass shrimp for one of the deeper shallow ponds. Both of the deeper ones flooded and have maintained sunfish populations up till now from the local stream. It will be interesting to see if they make it through all the ice cover we had this winter. I threw in 5 LMB last summer in an attempt to keep the sunfish under control, but I am not hopeful that they will survive. One of these shallow ponds get choaked with weeds and supports lots of invertibrates. It even has a healthy bladderwort population. These were intended to be fish free, but nature had another idea. It would be cool to have shrimp in there. Thanks again!
