I got my fish from a place that was about 1.5 hours from my place. They were placed in a very thick clear plastic bags filled as Theo said, half with water and the other half was injected with pure oxygen. For support the bags were then placed in a large foam transportation containers (looked essentially like a very big cooler). I moved about 3,000 two to three inch BG that way (and about 18 six to seven inch RES).
I think I lost 2 or 3 BG and no RES (at least at initial transfer, could have lost some in the days following, it would be real hard to tell on my pond).
