    Scientists Fear Leaping Carp to Invade U.S. Great Lakes

    February 21, 2006 — By Andrew Stern, Reuters


    CHICAGO — Fish that leap into passing boats may be a fisherman's fantasy, but scientists fear that hyperactive Asian carp will reach the Great Lakes, devour the base of the food chain and spoil drinking water for 40 million people.

    In less than a decade since escaping southern U.S. fish farms, the hardy and voracious carp have come to dominate sections of the Mississippi River and its tributaries.

    "It is a crisis," said Phil Moy of the University of Wisconsin and the government-affiliated water protection group Sea Grant. "We've seen some pretty significant adverse invaders in the Great Lakes. Right now, it's the carp, but what's around the corner?"

    The leaping fish are silver carp that jump haphazardly when alarmed by passing boats and have injured boaters, some of whom have taken up garbage can lids as shields.

    The only barriers between dense populations of silver and bighead carp -- two closely related Asian carp species -- and the world's largest collective body of fresh water are a few miles of waterway and a little-tested underwater electrical field spanning a canal near Chicago.

    The idea of adding a few more varieties of fish to the Great Lakes -- which have been abused by polluters, overfished, invaded by scores of unwanted species and repopulated with nonnative fish to eat invaders and please anglers -- would not appear catastrophic in light of the range of global environmental crises.

    But scientists believe the carp, which escaped lagoons in Arkansas during late 1990s flooding, could set off an ecological collapse in the lakes, ruining the primarily recreational $5 billion fishery and posing a threat to water quality for millions of people.

    "With invasive pest species, we can't turn back the clock, the lakes will be altered for good," said Cameron Davis of the group Alliance for the Great Lakes. "Not only do invasive species unravel the food web they also fool public perception: The lakes look cleaner because the food has been stripped out."

    Carp that can grow to 100 pounds filter huge amounts of water, consuming 40 percent of their body weight per day in microscopic plant and animal life that form the foundation of the aquatic food chain. The loss of this food relied on by crayfish and smaller fish such as alewifes, sculpins and perch would in turn eliminate the prey for popular game fish such as salmon, trout and bass.

    DEADLY ALGAE

    Lake water would become less cloudy, allowing sunlight to penetrate to greater depths and enhancing algae growth, some of which emit toxins that can cause itchiness, illness and even death. Varieties of toxic blue-green algae already hold an ecological advantage because they are avoided by the zebra mussel, another prolific Great Lakes invader that filters out plankton.

    Lake Saint Clair, which connects Lakes Erie and Huron, is sometimes choked with algae that tangles up boat props and swimmers, and algae blooms have fouled Green Bay off Lake Michigan.

    A few weeks each summer, bacteria that consume rotting algae lend a swampy taste to treated lake water. Rare bacteria outbreaks have fouled the lakes and made people sick, though advanced treatment systems have proven largely effective.

    The dire consequences from the carp's arrival may serve another purpose: publicizing the global issue of invasive species that cost hundreds of billions of dollars to fight.

    Public outrage that followed the Cuyahoga River catching fire in Cleveland in 1969 spurred passage of the Clean Water Act.

    Many ecologists have concluded the Great Lakes and Mississippi River watersheds need to be separated permanently.

    The temporary electric barrier -- a $9 million replacement is under construction -- guards a man-made channel that at the turn of the last century was dug to link the lakes and the Mississippi and to reverse the flow of the Chicago River, sending Chicago's sewage inland instead of out into the lake where it fouled the city's water supply.

    "The electric barrier is crude but it's the best thing we have now," said ecologist David Lodge of Notre Dame University. "The irony is the barrier was first proposed to keep round gobies (another fish invader in the Great Lakes) from colonizing the Mississippi River watershed, but by the time the barrier was built they had already passed it. Now the motivation is to keep the carp from coming from the other direction."

    Because many harmful invaders, though not the carp, arrived in ballast water dumped in Great Lakes ports by ocean vessels, one audacious proposal is to bar ocean vessels from the lakes.

    But such a drastic approach has drawn howls of protest from shipping interests, who instead are pursuing a foolproof method of killing the creatures that hitchhike in ballast water.

    International cargo, which is mostly imported steel and exported grain, carried by ocean-going vessels represents one-quarter of the 200 million tonnes shipped on the Great Lakes yearly, but as much as two-thirds of its value.

    A new species arrives in the lakes about every nine months. A few are introduced by fisherman dumping bait or aquarium owners setting animals loose. Illinois enacted a ban on transporting live carp out of fear of a Buddhist tradition that calls for setting one fish free for each one eaten.

    Lake watchers had a scare in 2004 when a Chicago fisherman caught a Northern snakehead, but no other examples have turned up of the voracious fish that can wriggle across land.

    I haven't eaten them but they are supposed to be very good to eat and folks out there are researching developing a markt for them.
    The Carpbusters Forum has recipes for the new asian carps, and commons, at www.carpbusters.com

    I had heard so many rumors, so I had to fry up some of the meat. The fillets are large, so I had quite a bit of extra and took it to a local bait shop around noon when everyone hangs out and tell stories. Everyone was eating it and commenting on how good it tasted. Some thought that it was spoonbill, since it was spring and the fillets were large. Others thought that it might be catfish from a large flathead. They did not believe me at first because of all the rumors about smell etc. Anyway, the meat is not strong tasting and very white. It breads and frys very nicely. I hope to try smoking some of the meat this spring.
    All that being said, there are Y bones in these fish very similar to the Y bones in a common carp. One advantage is that these fillets are so large, that you can fillet around the bones to some degree (they are in a line, but not connected to the ribs or spine). Also, these fish have a pink meat and vein along the sides that should be trimmed off (like many fish). The resulting meat to fry sometimes looks like long chickhen tenders when fried.
    Catching them is a bit tough except in the spring when they can be snagged as they stack up below the dams on the Mississippi or Illinois rivers. At that time, you can catch fish 10 to 50 lbs until you are exhausted. Landing a large asian in the tailwaters often takes 30 minutes or more with 80 to 100 lb line and a strong rod. It is almost a spectator sport to watch people fight the fish. Often you see someone give up the rod to rest. Remember, you have the fish by the tail many times!!! The fish run larger in the Missi and 40's are common. The MO state record is 75 and the national record was 90 lbs the last I saw. Just saw a picture of an 81 lber from Lake Texoma. The silver (jumpers) do not get as large as the bighead and can flat fly out of the water. You see them jump 20' across the water at times or go straight up in the air for 7 to 8'. In the spring, the silvers jump against the dam is a fashion that resembles salmon migrating. Many times, they make a great leap only to slam into the cement wall of the dam! Come visit!!!!

    Never tried it myself, but I'm sure if you fried it, it would taste just like any other fish, just cut into small chunks. Remember to remove that mud vein.

    A carp is any of various freshwater fish of the family Cyprinidae. The common carp (Cyprinus carpio) is the most common and best-known species of carp.
    [edit]

    Introduction of carp to North America

    Carp were introduced to England from western Europe during the 13th century, when they were cultivated mainly by monks. They were subsequently introduced into North America to great fanfare as "the world's finest fish" in 1877. The original shipment of 345 live fish were released in ponds in Druid Hill Park in Baltimore, Maryland. Later, surplus populations were released in Babcock Lakes in Monument Park in Washington D.C.. This was a project of Rudolf Hessel, a fish culturist in the employ of the United States Government. There was substantial favorable publicity and carp were widely introduced throughout the United States. Introduced Carp readily adapted to their new environment, spreading rapidly throughout any drainage area they were released in.
    Separating the Carp's reputed impacts from its actual impacts can be difficult. There is little evidence yet to support the claims of Carp eating the spawn of other fish. Tales of Carp muddying waters and destroying water weed through their bottom-grubbing feeding habits however are often accurate . Such raised turbidity may have serious impacts on aquatic ecosystems and submergent macrophytes ("water weed"), and loss of submergent macrophytes may also have serious effects on fish and invertebrate species reliant on them for habitat. In Australia, where the dominant Carp strain was illegally introduced, there is overwhelming anecdotal evidence and mounting scientific evidence that Carp do indeed raise water turbidity, destroy a number of submergent macrophyte species, and consequently seriously impact upon aquatic ecosystems and native fish species dependent upon those submergent macrophytes.
    While tasty when grown in good water, carp can be riddled with small bones in unpredictable locations. Most carp have a fishy taste and are not considered to be good for eating in North America, although they are popular in restaurants in Japan and Taiwan where the fish are also considered to be signs of good fortune. Carp is a traditional Christmas Eve dish in the Czech Republic, Germany and Poland.
    Despite having food and angling value that is celebrated in most parts of the world, in North America, Carp are viewed unfavorably. In Australia Carp are despised.
    Carp have taken much of the blame for the loss of native species in the U.S. It can be argued that US native fish populations were suffering even before introduction of carp. Over pressured freshwater fisheries are suggested as the reason why carp were originally stocked in the US. However, all introduced species have negative impacts on native fauna, particularly species like Carp that achieve high densities, and the introduction of non-native species for frivolous reasons such as sport fishing should not be encouraged or excused.
    Carp have an ability to survive in water that has been polluted by years of unregulated industrial discharge better than many sensitive native species. Carp extermination practices often take place, such as poisoning all fish in the lake then later re-introducing "desirable" fish. Because of the carp's hardiness, these efforts have been historically unsuccessful.
    The carp has not yet gained gamefish status in the U.S.; however, the carp is one of the hardest fighting freshwater fish to be found in the world. Europe in particular enjoys carp as a top angling resource. U.S. opinions may soon change due to new events and organizations that celebrate carp as a game fish. In 2005, the World Carp Championships are being held on the Saint Lawrence River in New York state. Teams from all over the world will compete in this 5 day tournament with the additional bonus of a $1,000,000 payout if any of the competitors breaks the New York state record of 50lb 4oz. But that being said, $1,000,000 is a drop in the bucket compared with the tax dollars spent to remove or reduce the numbers of this invasive fish.
