Would like to raise some shrimp to transplant to ponds. Was thinking of a 27 foot round grain bin ring. Berried 2.5 feet in ground with a liner put in it. Would they live and reproduce in it, without any air or up keep? Would need a bale of alfalfa put in for food. Would they need some dirt on bottom of tank? I put some in my 14 foot stock tank and they didn't live. I think water was to cold all year long. Would also like to try this with minnows. Anyone ever have success with this?
