locking barn door after VHS got out?

Let's hope not; at least Minnesota is trying.

VHS has caused large fish kills in the eastern Great Lakes -- including Michigan and Wisconsin -- and Minnesota officials fear if it shows up here in Lake Superior or the Mississippi River, it could spread to inland lakes with devastating consequences.

To reduce chances of that nightmare, legislation pushed by the [Minnesota] Department of Natural Resources is moving forward at the state Capitol to tighten laws restricting the transportation and stocking of fish. Under legislation, some bait fish and game fish used to stock lakes would have to be tested for the fatal fish virus.
