i can attest to the shipping personally. i live less than 40 minutes from these shipping routes.
it would shut down many many companies!

i wish it could be that easy. just look at the round goby which they still have done nothing about!

in times like these both sides look at things like this with a half stupid view.
round gobys are bottom dwellers i proposed to the indiana DNR that they implore sinking explosives down in the ports, sure it could hurt other species but those species are still being stocked.i found a round goby more than 200 miles from lake mich.

asian carp in lake mich. would not be a big problem. the problem is the tributaries of the great lakes where it would pose the biggest threat!
