Invasive carp compete with native species for food and habitat, so a healthy and diverse fishery is a positive sign.
34 silver carp captured in recent multi-agency operation.
Data will help agencies learn more about invasive carp.
A wholesale fish dealer from Platteville is facing state charges.
(Illinois DNR)Roy Sorce, owner of Sorce Enterprises, has teamed up with the Midwest Fishing Co-op to reduce the numbers of the fish and put another protein on the dinner table. “We are talking about 15 to 20 million pounds a year and that would help reduce the numbers and also less risk of them getting to the Great Lakes,” he…
Every flood drives destructive Asian carp further into North American waters.
The DNR says it’s the first documented capture of a grass carp from the lake that was diploid, or able to produce offspring.
In response to this discovery, the DNR is working with the U.S. Fish and Wildlife Service, the U.S. Geological Survey, the Wisconsin DNR and commercial fishing operators to conduct large-scale netting, studies of the captured carp and increased monitoring.
The fishing method is inspired by a traditional Chinese fishing technique. It involves setting a series of nets, underwater speakers and electrofishing gear to corral the carp.
An angler told the agency a silver carp jumped into his boat as he deployed a trolling motor.
The fence works as a deterrent by broadcasting noise at a frequency that irritates the carp. The noise is contained within a wall of bubbles that are lit by strobes. The combination has worked well in the laboratory and in smaller-scale outdoor settings.
(Illinois DNR)Wildlife agencies are stepping up waterway testing efforts following a spike in invasive Asian carp DNA detections in the Chicago River about five miles from Lake Michigan. Read the entire story here. Categories: Asian Carp, News Tags: Asian carp, Chicago River
A study led by University of Michigan researchers found that despite a drop-off in plankton, the tiny plants and animals on which bighead and silver carp typically feed, the lake has enough dietary options to sustain individual fish that venture away from nutrient-rich shoreline areas where most would congregate.
Some of the invasive fish reportedly from 20 to 30 pounds.
Thousands of the invasive carp reportedly clustering near the base of Lake Decatur dam.
The plan would use technology such as underwater loudspeakers, electric cables and air bubble curtains to deter the fish from migrating between the Illinois River and Lake Michigan through Chicago-area waterways.
The invasive was verified in the James River near LaMoure.
Efforts conducted June 3-14 included environmental DNA surveillance at more than 400 sites and investigation of 602 sites for fish.
The survey came after news broke that Gov. J.B. Pritzker wrote the U.S. Army Corps of Engineers a letter last week indicating that he had authorized the state’s collaboration with preconstruction, design and engineering work in the Brandon Road Lock and Dam near Joliet.
But a follow-up search turned up none of the invasive fish.
Location of choice is considered a crucial choke point where the invasive carp could be prevented from migrating upstream toward the lake.
A crew from the University of Toledo working with the U.S. Geological Survey found the larvae during sampling last June in the Maumee River, a Lake Erie tributary.
They have formed the Great Lakes Conservation Coalition, which will push for funding of a strategy proposed by the U.S. Army Corps of Engineers.
The Corps’ new plan is similar to a draft from August 2017, but the estimated price tag has jumped from $275 million to nearly $778 million.
FRANKFORT, Ky. — Kentucky officials say they are aiming to install a riverbed bubbler and sound system in Lake Barkley early next year as an environmentally friendly way to block the spread of an invasive fish. The Kentucky Tourism, Arts and Heritage Cabinet said the technology will be tested below Barkley Dam in western Kentucky. Several agencies in Kentucky and…
