Carp Attack Five things you need to know about the fish that might destroy the Great Lakes NWF Staff Sep 02, The fifth annual Redneck Fishing Tournament last August had dozens of small boats pulling away from the Boat Tavern in Bath, Illinois, for an Illinois River fishing contest in which no one was permitted to use a fishing rod, though nets were perfectly fine.
During the two-day tournament, contestants captured 3, Asian carp. One team alone brought in —the largest of which weighed more than 25 pounds. All the fish jumped into a boat or were scooped out of the air with landing nets. The Redneck Fishing Tournament was started in by Boat Tavern owner Betty Ford in an attempt to focus national attention on a developing environmental disaster—silver and bighead carp from Southeast Asia that have invaded Midwest rivers and that may soon move into the Great Lakes, where experts already have tallied more than exotic species from around the world.
What Are These Threatening Fish? Four species of Asian carp have invaded the United States—bighead, silver, grass and black. Of these, the greatest threats to U. Silver carp attract the most media attention, because they leap 10 to 15 feet out of the water when spooked by boats —or at least they do in U. Bighead carp rarely leap, even in the United States. Several boaters have suffered injuries from leaping silver carp, including broken jaws, noses, ribs, arms and legs after being hit by flying carp.
Dozens of carp may blast into the air at once, giving anglers a chance to net them from mid air. Neither species will bite a baited hook.
They feed by sucking up nearly half their own weight in algae and tiny aquatic animals every day. The fish can breed rapidly. A female big-head carp may produce 1. The carp are fast growers, too. Silver carp in captivity have reached 12 pounds within a year. This rapid growth allows them quickly to reach a size at which they are too big to fall prey to predators, such as walleye. Moreover, when young they tend to live at the surface of rivers, while local predators hunt in deeper water, allowing the carp to evade an important biological control.
Biology and Ecosystems. Apply Filter. What are Asian Carp? Carp are not native to North American waters, but various carp species have been introduced here since the mids, much to the detriment of native fish.
Although carp eradication measures have been active for over years, long-established species, like the common carp, are present in almost every state. Asian carp bighead, black, grass, and Can I eat Asian carp? Asian carp of all types have white, firm, mild flesh, which is excellent table fare, but all Asian carp also have intramuscular bones in the filets that many people find undesirable.
Asian carp feed low on the food web, are fast growing, are low in fat in the filets, and are not usually bottom feeders — all properties of fish that are lower in Is it possible to eradicate Asian carp once they are in an area?
Eradicating an established population of Asian carp would be extremely difficult and expensive, if possible at all. Potential control methods include the use of fish poisons, physical barriers, physical removal, habitat alteration, or the addition of predators, parasites, or pathogens. Research on Asian carp control is ongoing as part of the Asian What is an invasive species and why are they a problem? An invasive species is an introduced, nonnative organism disease, parasite, plant, or animal that begins to spread or expand its range from the site of its original introduction and that has the potential to cause harm to the environment, the economy, or to human health.
