Bighead Asian Carp Found In Chicago Sanitary and Ship Canal 12/3/2009
CHICAGO – The Asian Carp Rapid Response Workgroup announced this evening that a bighead Asian carp was found in the Chicago Sanitary and Ship Canal (CSSC) just above the Lockport Lock and Dam. This is the first physical specimen that has been found in the CSSC since eDNA testing earlier this year suggested the presence of Asian carp in the area.
“This is clearly a significant find in this operation that validates why it is so important for this work to be done,” said Illinois Department of Natural Resources Assistant Director, John Rogner. “We will continue to work with the U.S. Army Corps of Engineers and our partners on maintaining the integrity of the area around the barrier.”
Concentrations of Asian carp in the Lockport Pool are expected to be low compared to total biomass collected.
The Bighead carp was found 500 feet above the Lockport Lock and Dam near the west bank by a U.S. Fish and Wildlife Service Assistant Project Leader from the Carterville Illinois office. The fish is 21 and 7/8 inches long. Biologists working with the Asian Carp Rapid Response Workgroup began applying Rotenone Wednesday evening on a 5.7 mile stretch of the canal. Rotenone application was chosen as the best option of keeping Asian carp from breaching the electric barrier while it is taken down for scheduled routine maintenance. The application went as planned and clean-up efforts began around 8am this morning. The discovery of the bighead was found during those efforts.
Clean-up operations ended at sundown this evening and will resume around 7am tomorrow morning. More than 350 people have contributed to the efforts on the ground during this week’s operation.

This fish was above the lock and downstream from the barrier. As to there being only one, well if there is only one, that's a good thing. But I think there were probably more than one, whether they ever find them or not. Bighead and silver carp have a tendency to sink, not float, when killed with rotenone. See below..Also note the fish was 22", not the 22 pounds being reported now.http://www.freep.com/article/2009120...3/?imw=YKiller carp: In hiding or just a big fish tale?Cleanup near Chicago yields just 1 bigheadBY TINA LAMFREE PRESS STAFF WRITERLOCKPORT, Ill. -- As cleanup and Asian carp-searching efforts continued after a massive poisoning in the Chicago Sanitary and Ship Canal on Thursday, officials said they had found a lone Asian carp among the 200,000 pounds of dead fish.The bighead carp, nearly 22 inches long, was found just above the lock and dam at Lockport.That's one of many spots where DNA testing since July has shown the presence of carp.The find is important because it established that the DNA testing is correct. That same testing has shown that there are carp just below an even more critical lock, the O'Brien lock, 7 miles from Lake Michigan.A biologist who tested the poison on carp said Thursday that the fact that more carp weren't showing up dead in the canal wasn't surprising, since his tests showed they would sink to the bottom."There is a chance someone will find one or two," wrote Duane Chapman, a biologist at the U.S. Geological Survey in Missouri.Finding the single carp Thursday will only increase the drumbeat to close the canal off from Lake Michigan. "We're concerned," said Dan Thomas, president of the Great Lakes Sport Fishing Council. The Great Lakes Fishery Commission has pushed for several years to try to get studies done about how the engineering work might be done, said Marc Gaden, spokesman for the Great Lakes Fishery Commission. The canal was built more than 100 years ago to let ships move between the Great Lakes and the Mississippi River basin, and to allow Chicago to flush its waste down the river. Now, it's become a pathway for invasive species to pass back and forth between the bodies of water.

Below is some information on the DNA testing that Carptracker referred to. The University of Dotre Dame in IN has been conducting the testing, and back in June, our club helped provide them with a list of sites on the Des Plaines river where the Asians could be found.
Congrats to the researchers who now have another viable tool at their disposal.

Congrats to the researchers who now have another viable tool at their disposal.
ago Sanitary and Ship Canal – Aquatic Nuisance Species Dspersal Environmental (eDNA) Detection
Overview:
Fishes, including Asian carp, release DNA into
the environment in the form of mucoidal secretions, feces, and
urine. DNA degrades in the environment, but this process is
not instantaneous, and DNA can be held in suspension and
transported. The presence of species can be detected by
filtering water samples, and then extracting and amplifying
short fragments of the shed DNA. In contrast to other
surveillance methods, the environmental DNA (eDNA)
method does not rely on direct observation of Asian carp to
evaluate presence.

filtering water samples, and then extracting and amplifying
short fragments of the shed DNA. In contrast to other
surveillance methods, the environmental DNA (eDNA)
method does not rely on direct observation of Asian carp to
evaluate presence.
Scope:
Laboratory and preliminary field studies confirmed
that eDNA from Asian carps can be detected in 1 liter water
samples from sites with high, moderate, and low densities of
carp (see figure). Water samples are collected in the field and
filtered in the lab. DNA is extracted from the filtrate, and any
DNA from bighead and silver carp is amplified with PCR
using genetic markers that are unique to bighead and silver
carp. The eDNA approach uses standard genetic
identification methods in a novel application--the extraction of
low concentrations of DNA from water sampled in the field
that allows for species-specific detection.
The objectives of this study are to locate the invasion front
using the eDNA methodology and to compare the results with
other surveillance approaches. We will do this by completing
a longitudinal study of CSSC, sampling both the main-stem
and different microhabitats (pools, backwaters, side channels)
as we expect eDNA to accumulate in certain areas resulting in
an increased probability of detection. In addition, we will
increase the volume of water sampled as we sample around
the putative invasion front, as greater volumes may be needed
at low fish densities.
The data collected will allow an evaluation of detection probability
for variable water volumes and microhabitats that can be used to
inform improvements in the long term monitoring program. Data on
environmental covariates such as flow, pH, and temperature will also
be collected at each site to test how these variables influence
detection rates.

detection rates.
How will this improve our current monitoring?
The eDNA approach to surveillance will allow greater geographic
coverage throughout the CSSC and connected waterways, and should
be more sensitive at detecting low abundance of fish than the methods
currently employed. While adult carps are the most likely to be
detected with existing techniques, eDNA will be able to detect
juveniles as well as adults. Water sample collection can be
accomplished from boats, bridges, shorelines, in between the barriers,
and in habitats that are difficult to sample with the current approaches
(such as shallow channels of the Des Plaines River or deep sections of
the CSSC where electro fishing can be ineffective and high boater
traffic precludes the application of nets).
To calibrate the eDNA approach against current methods (e.g.,
electroshocking), we will conduct eDNA analyses on different
volumes of water taken from locations where current surveillance
methods are employed. Improvements over current methods would
then be achieved by routinely sampling larger volumes of water than
those necessary to match detection limits of the current methods.
To further increase the usefulness of eDNA in the surveillance
program, quantification of detection errors in experimental ponds or
flumes with known fish abundance would be necessary, but that is not
proposed here.

December 6, 2009
Maintenance on the electric barrier, IIA, was completed and the barrier was returned to operation at 10 p.m. on Friday, December 4.
"This has been a tremendous cooperative undertaking. Thanks to the outstanding efforts of our partner agencies from the U.S. and Canada, the Corps team was able to successfully complete this necessary maintenance and to do so ahead of schedule," said Col. Vincent Quarles, Commander of the U.S. Army Corps of Engineers, Chicago District.
"We appreciate the understanding and support of the navigation industry during this important maintenance operation. The Army Corps of Engineers is fully aware of both the economic and environmental importance of the area waterways," Quarles said.
The U.S Coast Guard (USCG) began enforcing a safety zone on the CSSC on December 2 in support of Asian Carp Rapid Response Operations. USCG has already restored access to parts of the canal and will continue to reduce the safety zone as the workgroup completes final phases of the operation.
In support of scheduled routine barrier maintenance, biologists working with the Asian Carp Rapid Response Workgroup began applying Rotenone, a fish toxicant, on Wednesday, December 2 on a 5.7-mile stretch of the canal.
“I want to thank each and every person and organization who put forth an extreme amount of time, energy and resources to make this project a success,” said Illinois Department of Natural Resources Assistant Director John Rogner. “The eDNA testing worked to give us an early warning. We took it seriously and we took action. The alternative was to do nothing and that would have been a mistake.”
Rotenone application was chosen as the best option for keeping Asian carp from breaching the lower voltage demonstration barrier while the more powerful Barrier IIA was taken down for scheduled routine maintenance. The application of rotenone and a detoxifying agent was successful and the clean-up of visible dead fish are complete at this time.
One Bighead Asian carp was discovered nearly 500 feet above the Lockport Lock on Thursday afternoon, December 3. Biologists with the workgroup believe there is a high probability that additional Asian carp were killed during the toxicant application but may not be found.
“The cold water temperatures on the canal this week means far more fish are sinking to the bottom of the waterway than will float to the top. Over the next several weeks and months, some fish may float to the surface but the majority of fish will break down naturally below the surface,” said Illinois Department of Natural Resources Fisheries Chief Steve Pallo.
The workgroup has collected thousands of fish, mostly common carp, from the canal since cleanup efforts began on December 3. Those fish are being disposed of properly in a landfill.
The public should be advised that dead fish may be observed from time to time over the next several weeks as some fish may rise to the surface. Public health officials always caution against eating dead or dying fish in any instance that have not been caught alive.
The workgroup is now focused on efforts above the electrical barrier system near T.J. Obrien Lock in an attempt to find Asian carp in areas where positive eDNA tests have been found. Positive Asian carp DNA evidence exists over nearly 10 miles of the Cal-Sag Channel and Sanitary and Ship Canal above the barrier.
The workgroup is using commercial fishermen, augmented with state and federal fisheries personnel, to deploy commercial fishing gear in a 5.5-mile stretch of the Cal-Sag Channel. Fishing operations are using nearly 2,000 yards of fishing nets deployed for two overnight periods. Nets have been deployed over portions of the reach since Dec. 1 and have been highly successful in collecting fish, although no Asian carp have been collected.
While the workgroup considered additional Rotenone application in specific areas above the barrier as a sampling option, there is no evidence to suggest Asian carp might be concentrated in any specific part of the 10-mile stretch of the canal where eDNA tests have been positive.
Water temperatures above the barrier are much colder than downstream where Rotenone was applied for the main project in support of scheduled barrier maintenance. At these temperatures, dead fish would likely never surface to be identified. Without identification, Rotenone would be ineffective as a sampling tool.
In contrast, fishing nets would effectively sample the entire reach and provide the best evidence of the potential presence and relative abundance of Asian carp in this stretch of channel. It would also confirm the exact location of any fish collected. Any Asian carp collected will be removed from the system, thereby providing a measure of population reduction.
“The effort near the O’Brien Lock is fundamentally different from the action below the barrier. The purpose of applying Rotenone below the barrier was to ensure no Asian carp advanced up the channel while the barrier was powered down. In addition, Rotenone would provide us little if any information about the presence and abundance of carp in this reach upstream,” said IDNR Assistant Director John Rogner.
The Asian Carp Rapid Response Workgroup and its partners are committed to remaining vigilant in the future and to explore all options available to prevent the spread of Asian carp to the Great Lakes.
The Asian CarpRapid Response Workgroup includes the Illinois Department of Natural Resources, U.S. Army Corps of Engineers, U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service, U.S. Coast Guard, USDA Animal and Plant Health Inspection Service, Chicago Department of Environment, Metropolitan Water Reclamation District of Greater Chicago, Midwest Generation, Great Lakes Commission, Great Lakes Fishery Commission, International Joint Commission, and Wisconsin Sea Grant. Fisheries management agencies from Indiana, Wisconsin, Michigan, Minnesota, Ohio, Pennsylvania, New York and Canada have also provided support to the operation.

December 8, 2009
CHICAGO – The Asian Carp Rapid Response Workgroup has completed fishing operations near the T.J. O’Brien Lock in an attempt to locate Asian carp after eDNA sampling in the area tested positive for the invasive species. The Workgroup used commercial fishermen and federal fisheries personnel to deploy nearly 3,000 yards of fishing nets along a 5.5-mile stretch of the Cal-Sag Channel. While the nets were successful in collecting more than 800 fish, no Asian carp were found. The catch included more than 700 common carp and 10 other species.
The fishing operations that began on Dec. 1, wrapped up late yesterday, Dec. 7. On Monday evening, the U.S. Coast Guard reopened the Cal-Sag Channel and Little Calumet River to vessel traffic.
While the fishing operations and the Chicago Sanitary and Ship Canal rotenone application have thus far confirmed just one Bighead Asian carp, the Workgroup expects their work to continue for some time.
eDNA is serving its purpose as an early warning system and suggests that Asian carp may have reached the Cal-Sag Channel. Based on recent sampling and the fish collection efforts there, the Workgroup believes that if Asian carp are present, their numbers are likely very small. The Workgroup and its partners are committed to remaining vigilant in the future and exploring all options available to prevent the spread of Asian carp to the Great Lakes.
Among the next steps already underway to prevent the spread of the destructive fish to the Great Lakes:

Thanks for all the info Bulz and Duane. It was funny, when that guy from the Asian Carp work group called me, I was shopping at Costco. I'm standing in the produce section trying to talk invasive carp. I was getting a lot of weird looks. (more than usual) 
Thanks for being our 'Location Liaison'.

Chris, one of the head researchers with the eDNA project, hopes that the new technology may be used to monitor other invasive species like Snakeheads and even endagered ones like Sturgeon.
There is a lot of excitement over at Notre Dame right now.
