Asian carp waking illinois river


Some of the carp caught at Redneck Fishing provide research that can prevent the invasive species from entering the Great Lakes. At the annual Redneck Fishing Tournament in early August, teams of Asian carp catchers unload their hauls into a semi-trailer full of the invasive, dead fish.

Most of the harvest went to cat food and fertilizer factories, but several dozen were taken by Asian carp waking illinois river U. Jan Jeffrey Hoover, a research fishery biologist for the U. Army Engineer Research and Development Center in Vicksburg, Mississippi, went to the Redneck Fishing Tournament in the small western Illinois town of Bath to take measurements from the larger carp caught at the event.

These measurements will help the corps replicate their serendipitous success at blocking large numbers of Asian carp from the Upper Mississippi River.

At Redneck Fishing, the race to net the most Asian carp in four separate heats resulted in a catch of more than 2, of the fish. The carp that elude capture continue up the Illinois River and are prevented from reaching Lake Michigan by an electric barrier. The corps already has a series of electric barriers in the Chicago Sanitary and Ship Canal, which connects to Lake Michigan. But despite "Asian carp waking illinois river" largely successful track record, a live Asian Carp was recently found just a few miles away from Lake Michigan, according to the the Chicago Tribune.

It could have been carted there by a bird rather than jumping the barrier — scientists are unsure, Asian carp waking illinois river said. If funding is approved, the jet-enabled new layer of protection would have to be fine-tuned to keep out silver carp, a greater threat than the bighead carp, both of which are found in the Illinois and Des Plaines rivers, Hoover said. Silver carp, unlike bighead carp, jump when stirred by a wake and noise. They also occur in substantially larger numbers and have higher burst-swimming speeds than the bighead carp.

Both types of carp have gradually inched closer to Lake Michigan since flooding from fish farms in southern states introduced them into the Mississippi River in the late s. Finding the right water flow to impede Northern Illinois-adapted carp requires data on fish length and weight, which Hoover gathered at the event.

He only picked the largest fish because they swim faster. Having weight and length measurements for the fastest fish will allow the corps to develop maximum water velocities that prevent most carp from moving upstream. Data are also gathered using water tunnels like this to evaluate swimming behavior and endurance at different water velocities.

Hoover also collected data that will be useful for lowering the count of Asian carp in Illinois rivers through other harvest events like Redneck Fishing. Bath — and its slice of the Illinois River — is a global hotspot for Asian carp. Not only does the yearly Asian carp waking illinois river help keep the population in this section of the river at bay, but it also gives scientists hundreds of fish to choose from for scientific study.

Lifelong Bath resident Robin Daniels has volunteered at every Redneck Fishing tournament since the extravaganza began 11 years ago. While they were able to fill a semi-trailer full of the Asian carp waking illinois river, prior years had much larger harvests. The turnout this year was lower, and the water level was high due to rain — making the fish less likely to jump, she said.

I would have never thought of seeing a flying fish back in those days.
