Asian Carp Regional Coordinating Committee 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

Asian Carp Regional Coordinating Committee 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 SILVERBIGHEAD (From Mandrak and Cudmore and Kolar et al) BIGHEAD SILVER

Asian Carp Regional Coordinating Committee Chronologic Upstream Movement of Asian Carp
9
Asian Carp Regional Coordinating Committee Detection above barrier –Silver = 2.9% positive –Bighead = 5.7% positive Stopping the Spread: Monitoring and Detection Monitoring –Netting, electrofishing, ballast sampling, tagging –eDNA tests above and below barrier Positive eDNA Detections above barriers

Asian Carp Regional Coordinating Committee Barrier Effect
11
Asian Carp Regional Coordinating Committee Stopping the Spread: Electrical Barriers 800’ 220’ Chicago Sanitary and Ship Canal Lake Michigan Water Flow 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 I (Demonstration): ₋ In continuous operation since 2002 - 1 volt/in, 5 hz, 4 ms -Rehabilitated in Oct 2008 Barrier I (Permanent): -Upgrade to a permanent barrier authorized -Plan activation by 2013 if funded I IIB IIA Other Ongoing Efforts: -Asian Carp Monitoring -Research on Optimum Operating Parameters -Study of Solutions to Potential Barrier Bypasses Barrier IIB: ₋ Site prep completed ₋ Building construction contract NTP issued 3 Dec ₋ Electronics design ongoing ₋ Construction to be completed 30 Sep 2010

13
Asian Carp Regional Coordinating Committee 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
14
Asian Carp Regional Coordinating Committee 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
15
Asian Carp Regional Coordinating Committee Strategic Framework: Short-and Long-term Actions
16
Asian Carp Regional Coordinating Committee 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.”
17
Asian Carp Regional Coordinating Committee 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
18
Asian Carp Regional Coordinating Committee 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
19
Asian Carp Regional Coordinating Committee 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
20
Asian Carp Regional Coordinating Committee 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
21
Asian Carp Regional Coordinating Committee Ecological separation might entail... –New infrastructure o 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 Separation?
22
Asian Carp Regional Coordinating Committee 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. The Future: Ecological Separation?
