Evaluating Electric Barrier Effectiveness for Asian Carp using Telemetry-Based Fish Tagging

This research investigates the effectiveness of electric barriers in preventing Asian carp movement in the Upper IWW/CAWS. Utilizing individually coded ultrasonic transmitters, 200 fish, including bighead and silver carp as well as surrogate species, were tagged and monitored. The study aimed to assess whether these fish could breach barriers and navigate lock structures. Initial findings indicate high detection rates of tagged fish, with no breaches observed at the barrier. The study lays the groundwork for future telemetric approaches to manage invasive species effectively.

  1. 2.3.4 Tagged Fish Research to Test Electric Barrier Effectiveness Kelly Baerwaldt USACE

  2. MRRP Telemetry • Tagging of fish with individually coded ultrasonic transmitters in the Upper IWW/CAWS; • Acoustic network supplemented by a mobile hydrophone unit to collect information from tags (N=200) implanted into free-swimming Asian carp (bighead carp and silver carp) and surrogate species; • Purpose is to monitor fish movements in the immediate vicinity of the Barrier to determine if fish are able to challenge and/or penetrate the Barrier; if Asian carp are able to navigate through lock structures in the Upper IWW; and to determine the leading edge of Asian carp.

  3. 2011 Planned Effort 2010 Effort • 105 tags implanted into adult Asian carp and surrogate species (July - Nov 2010) • CSSC/Chicago River above Barrier: 20 common carp • Lockport Pool above Barrier: 18 common carp; 2 freshwater drum • Lockport Pool below Barrier: 29 common carp • Brandon Road pool: 1 grass carp; 1 smallmouth buffalo, 17 common carp • Dresden Island pool: 17 bighead carp • 60 tags into adult surrogate species (Lockport Pool) and Asian carp and surrogate species (Brandon Road Pool) • 5 tags into Asian carp in Dresden Island pool • 30 additional tags to be implanted into small fish (species TBD) in Lockport pool below and between the Barriers • 15 tags in spring (high water) • 15 tags in late summer (low water) • Mobile tracking 200 TAGS TOTAL 2.5 yr battery life Transmitter being implanted into Asian carp Transmitter size relative to size of Asian carp

  4. Telemetry Path Forward MRRWG Telemetry Master Plan: GOAL • Priority Areas: • At Barrier • Below Barrier • Above Barrier USACE Stationary Receiver (14) MWRD Stationary Receiver (14) *Will add 4 more armored receivers around Barrier TOTAL: 8 Barrier Receivers; 32 System Receivers Above barrier: 40 tags implanted Surrogates only * At and Below barrier: 138 tags by Spring 2011 Lockport pool: surrogate only (adult and juvenile) Brandon Road: surrogate and Asian carp Dresden Island Pool 22 tags implanted into Asian Carp Brandon Rd Lock 105 tagged fish thru NOV 2010 (actual) 200 tagged fish by Summer 2011

  5. Summary: Stationary Receivers • Data collected 21 July – 27 Oct 2010 • 621,091 detections • 54 tags detected • Single ‘hit’ data discarded • No tagged fish crossed Barriers

  6. October Mobile Tracking Data • 41 Tags Detected • 4 days tracking • 7 tags detected by Mobile Tracking not detected by receivers

  7. Barrier Receivers • Around Barrier = 519 detections (3 tags) • 3 common carp were detected in range of Barrier; all detected next day by downstream receivers • Two fish detected around Barrier in October; one in September • No evidence of Barrier breach Armored Receivers CSSC Barrier I Cal-Sag Barrier IIA Des Plaines River Barrier

  8. Barrier Receivers • Need better detection resolution of fish at Barrier to determine EXACT location of fish in detection range • 2011: Procure four VR4 Receivers • Deploy for five years • Surface downloads (modem, no need to retrieve receivers) • Positioning data can determine EXACT location of fish, data is processed by Vemco • Pilot study in March; not available for retail until June

  9. Summary • No tagged fish have crossed Barrier • 61 Tags detected July - Oct • CAWS: 61 out of 87 tags detected (70%) • 18 tags were implanted in Nov, not included in detection rate analysis • High rate detection considering open system and use of passive detection; more active detection to be used in 2011 • Lockport Pool Below Barrier: 29 out of 29 tags detected (100%) • New VR4 Receivers to be deployed June 2011 THANK YOU to ILDNR and USFWS for tagging and field assistance
