  • Comments
why we re worried
Why we’re worried
  • Large bodied (>100 lbs)
    • Bighead: 5 feet, 90 pounds
    • Silver: 3 feet, 60 pounds
  • Eating machines
    • Up to 20% of body weight/day
    • Planktivores
    • Eat same food as natives
  • Reproduce, develop quickly
    • 1 female = 1- 500 million eggs
    • Grow to ~10” in year 1
  • Tend to jump when startled
range and spread
Range and Spread
  • Can adapt to northern temperate zones
  • Currently within striking distance of the Great Lakes

Reproduce, develop quickly

    • 1 female = 1- 500 million eggs
    • Grow to ~10” in year 1
  • Tend to jump when startled

stopping the spread monitoring and detection
Stopping the Spread:Monitoring and Detection

Positive eDNA Detections above barriers

  • Detection above barrier
    • Silver = 2.9% positive
    • Bighead = 5.7% positive
  • Monitoring
    • Netting, electrofishing, ballast sampling, tagging
    • eDNA tests above and below barrier
stopping the spread electrical barriers
Stopping the Spread:Electrical Barriers

Lake Michigan

Water Flow

  • Barrier I (Demonstration):
  • In continuous operation since 2002
  • - 1 volt/in, 5 hz, 4 ms
  • Rehabilitated in Oct 2008
  • Other Ongoing Efforts:
  • Asian Carp Monitoring
  • Research on Optimum Operating Parameters
  • Study of Solutions to Potential Barrier Bypasses

I

  • Barrier I (Permanent):
  • Upgrade to a permanent barrier authorized
  • Plan activation by 2013 if funded

Chicago Sanitary and Ship Canal

800’

  • Barrier IIA:
  • Activated @ 1 Volt/in, 5 hz, 4 ms in APR 2009
  • Increased to 2 Volt/in, 15 hz, 6.5 ms in AUG 2009
  • Maintenance shutdown completed Dec 2009
  • Barrier IIB:
  • Site prep completed
  • Building construction contract NTP issued 3 Dec
  • Electronics design ongoing
  • Construction to be completed 30 Sep 2010

barrier status and funding
Barrier Status and Funding
  • Construction Status
    • Barrier I activated in 2002
    • Barrier II A activated in 2009
    • Barrier II B to be completed in late 2010
  • Funding Status
    • Funding provided in federal budgets
    • Construction and operations
stopping the spread rapid response
Stopping the Spread:Rapid Response
  • December 2009, Barrier IIA down for maintenance
  • 400+ respondents, XX agencies and organizations
  • Results…
    • Barrier maintenance success
    • Confirmed presence of Asian carp in canal
asian carp control strategy framework
Asian Carp Control Strategy Framework
  • Goal: Prevent establishment of self-sustaining carp populations in the Great Lakes
    • Integrate and unify future actions of participating agencies, develop collaborative approach
    • Transition to multi-tiered defense (beyond barriers)
  • Dynamic document based on growing body of knowledge gained from research and monitoring
  • Strategy: “…move quickly on proven solutions, and consider, develop, and test potential solutions and employ those that are most sound.”
framework short term actions
Framework:Short-term Actions
  • Carp population suppression measures
  • Enhanced detection measures
    • Increased sample collection
    • eDNA indicator refinement
  • Structural operation variations
  • Emergency engineering measures
  • Expedited biological control assessments
  • Enhanced electric barrier operations
framework long term actions
Framework:Long-term Actions
  • Efficacy study
  • Inter-basin feasibility study
  • Ecological-separation
  • Modified lock operations
  • Commercial market enhancement and ongoing fish population suppression
  • Biological controls
framework funding
Framework:Funding
  • Short-term actions
    • $38.6 million
  • Long-term actions
    • $39.9 million
  • Funding Sources
    • Great Lakes Restoration Initiative: $57.4 million
    • Base Program Funding: $21.1 million
the future ecological separation
The Future:Ecological Separation?
  • Ecological separation means…
    • NO interbasin transfer of aquatic organisms
    • PREVENT the movement; 100% effectiveness
  • Ecological separation does not necessarily mean…
    • Stopping shipping or recreational traffic
    • Lock closure
    • More frequent or more severe floods
the future ecological separation1
The Future:Ecological Separation?
  • Ecological separation might entail . . .
  • New infrastructure
    • E.g.: Lift lock for recreational vessels, similar to the Big Chute Marine Railway on the Trent Severn Waterway, Ontario
  • Chemical/heat barriers
  • Altered traffic flows (commercial and recreational navigation)
  • Changes to hydrology
  • Different management of stormwater and wastewater
  • Improved transportation infrastructure
  • Enhanced infrastructure for tourism
  • Ecological restoration of waterways
the future ecological separation2
The Future:Ecological Separation?
  • USACE “Feasibility Study”
    • Corps authorized to investigate “range of options” for separation
    • Multi-year study
  • Other elements for others:
    • Investigate the transportation and water management needs for the region;
    • Propose new infrastructure needs;
    • Take into consideration all connections that need to be severed.
