Water Resources Reform and Development Act Report
Today the U.S. Fish and Wildlife Service released to the public the second annual report to Congress on activities and expenditures to manage the threat of Asian carp in the Upper Mississippi and Ohio River basins. The report, developed pursuant to the Water Resources Reform and Development Act of 2014 (WRRDA), provides a summary of detection, prevention, control and management actions conducted by federal and state agencies to address the threat of Asian carp within the two river basins from July 2014 through September 2015.

Monitoring and Response Plan and Contingency Plan
The Asian Carp Regional Coordinating Committee (ACRCC) today released its first Contingency Plan which outlines member agencies’ preparedness to defend the Great Lakes from Asian carp in the Illinois River system. The Contingency Plan identifies actions partners will take if Asian carp are detected in new areas or if greater numbers of fish are observed. The plan complements the ACRCC’s 2016 Monitoring and Response Plan which details the scientific basis for control and management efforts to prevent the spread and establishment of Asian carp from the upper Illinois River into the Great Lakes.

On June 18, 2015, three Silver Carp larvae were collected, approximately a mile-and-a-half upstream of the I-55 Bridge (Channahon, Illinois), in the Dresden Island Pool of the Des Plaines River (River Mile (RM) 279.3).  These individuals ranged from 8.5 – 10.0 mm (0.33-0.39 inches) total length.  Asian carp eggs (either Silver or Bighead Carp) were also identified from samples collected from Marseilles and Starved Rock pools of the Illinois River, as well as from downstream pools (LaGrange and Peoria).

ANN ARBOR—If they successfully invade Lake Erie, Asian carp could eventually account for about a third of the total weight of fish in the lake and could cause declines in most fish species—including prized sport and commercial fish such as walleye, according to a new computer modeling study.

On October 22, 2015, as part of an on-going comprehensive monitoring plan for assessing location and populations of Asian carp in the Illinois Waterway, U.S. Fish and Wildlife Service (USFWS) sampling crews detected two small silver carp in the Marseilles Pool of the Illinois River. This site, near Moody Bayou, upstream of Seneca, Illinois, marks the furthest upstream location fish of this size have been captured. The fish, captured via electrofishing and measuring about 6.5 inches in length, will be aged by researchers to determine what year they were spawned.

This past year, the U.S. Fish and Wildlife Service conducted studies to test whether small fish could become trapped in the underwater spaces between commercial barges and inadvertently transported over various distances and across electrical barriers. The U.S. Army Corps of Engineers operates a system of three electrical fish dispersal barriers in the Chicago Sanitary and Ship Canal, which are designed to prevent the movement of non-native fish, including Asian carps, between the Great Lakes and Mississippi River basins. Research used golden shiners to examine the impact of commercial barge traffic on small fish movement to better understand the potential risk of small Asian carp passing through the electrical fish dispersal barriers in the Chicago Sanitary and Ship Canal.
