And what about the MN river too? That's good. We KNOW for a fact that it won't work BUT we're going to spend millions upon millions to give it a try anyway. Good ol' gov at work again.

So, an electric barrier won't work but the less effective sonic/strobe/bubble barrier will? Sounds fishy to me! Come on DNR stand up to the federal Corps of Engineers and insist on an electric barrier or close the lock. Maybe our US House and Senate members can defund operation of the lock as a money saving measure. This is one lock and dam the US taxpayer can't afford anymore.

(from the article) "That leaves sound and bubble barriers as the only possible deterrent to the invasive fish..." ---- Yup. Those ideas will work. My fish in their fishtank are terribly annoyed by loud music and especially the rock-bubbler. DNR: STOP WASTING GRANT MONEY!

It's simple: close the lock. The riverfront upstream from Ford dam is being transitioned away from industrial use anyway. It doesn't see a great deal of commercial use compared with other locks.

Wait and ignore the problem...disregard scientific studies that clearly illustrate the threat...then claim defending against it is not financially feasible. Newsflash: The Flying Carp do not Care! Massive Fail.

crossing the PC barrier here, but if the DNR would announce that there is unlimited open season now and forever on the species, and more, than each dorsal fin pays a $5 bounty, we have hordes of people who would tie-line themselves to the banks and scoop those buggers out of the water 24x7.

We need to start eating these fish. The reason the carp are in the States is because people from their native habitat thought them too tasty to leave behind. We've got a latent industry here just waiting to be exploited. A Asian carp fishing contest with a moderate prize and a web site with recipes and the problem would be gone in no time at all. Never underestimate the power of a pro-tournament!

The light and bubble barriers are 50 to 70 percent effective. This is no protection at all. Its 19 million dollars down the drain. Why don't they go down to Keokuk Iowa and put in a electric barrier. This will protect a lot more of the states waters and and be a more effective deterrent. Lets not make another political decision that has little or no chance of succeeding. Democrats were watching.
