If Asian carp ever get into the Great Lakes, fun in boats as shown above could well be a thing of the past. These invasive fish jump out of the water when disturbed by noise and vibrations. With an average weight of 30-40 pounds and some weighing in over 100 pounds, they can cause injury or death to boaters.
The Freep reports that a plan tentatively recommended by the Army Corps of Engineers to keep Asian carp from the Great Lakes would cost $275 million plus annual costs for maintaining and operating it of nearly $20 million a year:
Of all the options considered by the Army Corps for blocking the advance of Asian carp at the Brandon Road Lock and Dam in Joliet, Ill., the tentatively selected plan was the most expensive. It would use noise to block the fish, along with an electric dispersal barrier, water jets, a flushing navigation lock and more.
…The plan, however, doesn’t guarantee success: The Army Corps estimated the species known as Asian carp would still have a 10%-17% probability of becoming established in the Great Lakes, down from 22%-36% if no action was taken.
The Corps estimated that closing the navigation lock altogether would have the greatest likelihood of stopping bighead carp and silver carp — the two invasive species that are known as Asian carp — from reaching Lake Michigan, bringing the probability down to 1%-3%. But the cost to inland shippers and the companies they serve would be in the hundreds of millions of dollars with some shippers going out of business.
I hate to be a jerk, but PUT THOSE SHIPPERS OUT OF BUSINESS. Asian carp in the Great Lakes would be a disaster* and seriously impact BILLIONS OF DOLLARS in wages tied to the health and recreational value of the Great Lakes.
