Meanwhile waterfowl/wading birds are free to fly from waterway to waterway with no restrictions 
Someone needs to make a law that they can't do that and they will be fined and incarcerated if they do!

Sorry couldn't resist.
I do get your point.
The feds made testing for a virus mandatory on fish farms in the Great Lakes region. Never mind it's never been found on a fish farm and probably never will be. Meanwhile it's source still goes unchecked -- ballast water from ships coming in from all over the world. I think we are up to 118 exotic fish, plants, mussels, zooplankton, viruses, etc. that have mostly come in with ballast water as far away as the Caspian Sea.
