<BLOCKQUOTE>quote:</font><HR>St. Paul, Minnesota-AP -- Minnesota officials are studying whether to build an underwater electric fence across the Mississippi River to prevent the northward spread of Asian carp.
Electrified cables or bars on the river bottom would shock fish as they swim toward it.
The barrier might be installed somewhere between the Iowa border and the Minneapolis-St. Paul area if a study concludes that it would work.
Two exotic species of carp -- silver and bighead -- have been moving upriver since the 1980s, after they were imported by Arkansas fish farmers and apparently escaped.
The fish can weigh more than 60 pounds.
When motorboats pass through waters infested with silver carp, the fish jump several feet out of the water and sometimes land in boats. The airborne fish have injured boaters and damaged equipment.<HR></BLOCKQUOTE>MY OPINION: As if damaged boat equipment was the only reason to stop the spread of silver carp.
Sounds like an interesting idea, but all it will take is an hour's worth of power outage to let a couple hundred across the barrier, then all will be for naught. Seems to be a futile effort.
