EPA sued over new ballast water discharge rules.

dont forget rock snot, its invasive too

I don't think we want to stock more forage fish in Great Lakes as some of them are threatening to the rare and threatened Great lakes cisco/whitefish species such as Bloater, Kiyi and smaller whitefish species. Rainbow, steelhead, brown trouts and any salmon species are not native to the Great Lakes except the lake trout and the brook trout. And Great Lakes do not need another exotic gamefish like wipers or stripers to make the problems more worse, we have ENOUGH gamefish swimming in the Great Lakes. Thats right salmons and trouts are on Exotic List of Great Lakes. I personally think stripers/wipers are better off in the smaller inland lakes that's not connected to Great Lakes.

iam am aware that most salmon and the trout are exotic/ implanted species. but only coho are really taking hold this fall we had a record # of cohos and a very low king #. most cohos we catch around here are river spawned as they cary no tags or cut fins. trout populations are self sustaianing as well so they should be left.

I would feel the same way about stripers but they have made there way to the great lakes there is no large population "yet" but they are there. Any time i go to the local bait shops they have pictures of ones caught. and yes i asked the owner where they were caught. Ive talked to two people that have caught them. And no they were not white bass these where all over 8 pounds, they were longer and thinner then white bass as well.

Hmm I hope stripers dont reproduce in Great Lakes but then pacific salmons can reproduce in the Great Lakes then I believe stripers can reproduce in Great Lakes as the lakes are pretty big. I wonder how stripers get in the Great Lakes? Probably escaped from fish hatchery farms or from ballast water. And that is how the invasive white perch get in Great Lakes.

definate possiblity there, they can also get in from indiana where they stock them in there reservoirs which are connected to our rivers

naturally.
thats why we have gobies, zebra/quagga mussels, dungeness crabs, mitten crabs, and comb jellies.

Let's not forget ruffe and the spiny water flea

Let's not forget about white perch, alewifes, sea lamprey and three spined sticklebacks. They are not native to Lake Superior.

River Ruffe didnt come in from ballast tanks. Bait bucket and aquarium releases.

White Perch and Sticklebacks are not from Ballast. White Perch actually moved gradually inshore from the eastern seaboard, not introduced. Sticklebacks are from bait bucket releases.

this summer we had a record catch of white perch, every where i went i caught some and every body else was catching them and they thought they were white bass, but they had no stripes just yellows broken bands, near the top of there body.

And thats where you're wrong. Ruffe do come in from ballast as they are NOT American species but an European species. Why we need to order baitfish overseas especially from Europe? So it wasnt bait release. Ruffe are not popular aquarium fish..so it couldnt be aquarium release.

White perch invade the Great Lakes through the canals which the ships used often.

Three spined stickleback wasnt bait released, they invaded Great lakes through the canals.

But they could come in from ballast...not just use the canals but use different ways to get there.

how does a juvie Perch come in thru ballast? and ruffe? no ship is coming from a river in europe to the great lakes w/out dumping ballast. plus the saltwater in the ballast would kill a River Ruffe.
White Perch and Sticklebacks invading thru canals makes. sense. but to some extent did spread through natural water.
