Asian Carp Sampling Summary - Week of June 27, 2011

 *Note that these data are field summaries that are provisional and subject to revision pending thorough review.

No bighead or silver carp were captured or observed above the Dispersal Barrier nor were any found in new locations downstream of the Barrier.

Reach Sampling Upstream of the Dispersal Barrier

Reach 1: CSSC to Stickney Water Reclamation Plant (WRP)

Reach 2: CSSC and Cal-Sag Channel junction to Calumet Harbor

Reach 3: CSSC from Stickney WRP to Chicago Lock

Reach 4: North Branch Chicago River to Wilmette Pumping Station

One INHS electrofishing boat and crew electrofished at Reach 4 (North Shore Channel and North Branch Chicago River) on June 28.  Sample effort totaled 16 electrofishing runs (15 minutes each; 4.0 hours total).  A combined total of 294 fish representing 12 species were sampled during the effort.  No bighead or silver carp were captured or seen.   A catch summary is listed below.

DIDSON Barrier Efficacy Project

USFWS (Carterville and La Crosse) with help from the USACE (Rock Island and Chicago Districts) performed wild fish DIDSON studies at the electric fish barriers from June 28 – July 1.  Approximately 10.0 hours of DIDSON recordings were obtained in and around barriers 2A and 2B.   Videos will be reviewed and analyzed and then discussed in a final report after project completion.

Barrier Defense Asian Carp Removal Project

Dresden Island Pool:  10-24 miles downstream from Dispersal Barrier

Marseilles Pool:  24-51 miles downstream from Dispersal Barrier

Starved Rock Pool:  51-65 miles downstream from Dispersal Barrier

One IDNR boat and crew assisted crews from  SIUC in the marking phase of a mark-recapture study of Asian carp at the Hanson Material Services gravel pits near Morris.  This is the site in the Marseilles Pool of the Illinois River that receives a large portion of the fishing effort for the  Barrier Defense Removal Project.  Crews marked over 500 Asian carp during the effort.  The recapture sample will begin July 12,  the next scheduled date for  commercial harvest below the barrier.

Larval Fish, Zooplankton, and Productivity Monitoring

Monday, June 27

From June 27-July 3, one INHS boat and crew and one Western Illinois University (WIU) boat and crew sampled larval fish, zooplankton, and water quality from 21 locations on the Illinois River, lower Des Plaines River, and CAWS.  This sampling effort included all of the 21 sites designated for larval fish/productivity sampling.  Samples are currently being processed and results will be made available upon completion of sample processing.

Gear Evaluation Study
One INHS boat and crew sampled with multiple gears in the La Grange Pool of the Illinois River near Havana (river mile 116) from June 27-29.   Twelve types of gear were evaluated at each location.  A combined total of 3,004 fish representing 31 species and 1 hybrid group were sampled.  The catch included 44 Asian carp.  Of those, 7 were silver carp, 14 were bighead carp, 15 were obvious bighead x silver carp hybrids, and 8 were grass carp.

A summary of sampling effort and catch is listed below.  Note that catches for similar gears were combined for the summary.

Upper Des Plaines River Monitoring Project
One boat and crew from USFWS-La Crosse with assistance from MWRD completed  electrofishing and trammel/gill net sampling in the upper Des Plaines River at Lemont and Columbia Woods sites on June 28 and 29.  Sampling at a third site near Riverside was postponed to a later date in July.  Effort included 2.0 hours of DC electrofishing and 466 yards of net at Lemont and 2.25 hours of electrofishing and 666 yards of net at Columbia Woods.  A combined total of 466 fish representing 26 species were sampled during the effort.  No Asian carp were captured or seen.
