A three stage outreach transferability program of decision making tool to prevent, manage, and control Asian carp populations in Lake Michigan tributaries based on the evaluation of transport of eggs of local Asian carp populations

  • Develop an outreach plan for technology transfer targeting three stakeholder groups: technical and scientific community, decision makers, and K-12 students and general public
  • Train and instruct the technical and scientific community on how to use and
    interpret FluEgg as a decision making tool, but also to educate decision makers and the general public on the importance of preventing, controlling and managing Asian carp at early life stages

Aquatic nuisance species – evaluating the ecological and economic value of the 100th Meridian Initiative

  • In what parts of the Columbia and Colorado river and reservoir systems are zebra mussels likely to thrive if they are introduced from infested eastern waters?
  • For those parts of the target river systems that meet the ecological requirements of zebra mussel, what a) environmental goods and services, and b) financial and commercial goods and services are at risk?
  • What are the costs and how effective are different prevention strategies? For the 100th Meridian Initiative, what is the most cost-effective level of investment in prevention and control?

Aquatic nuisance species: an evaluation of barriers for preventing the spread of Bighead and Silver carp to the Great Lakes

  • Evaluate the effectiveness of electric barriers in restricting the movement of bighead and/or silver carp
  • Evaluate the effectiveness of acoustic/bubble barriers in restricting the movement of bighead and/or silver carp
  • Evaluate the effectiveness of combined barrier types (i.e. electric / acoustic / bubble) in restricting the movements of bighead and/or silver carp

Bighead carp in the upper midwest river: competition with native filter-feeding fishes and potential threats to the Great Lakes

  • To determine the extent of dietary overlap between bighead carp and native filter-feeding fishes in the Mississippi and Illinois river systems
  • To use data from the Long Term Resource Monitoring Program to examine whether specific environmental factors correlate with successful reproduction of bighead carp in the Upper Mississippi River System
  • To test the effectiveness of an electric barrier in restricting the spread of bighead carp

Dispersal of Exotic Species in the Great Lakes: Crayfish as a Model System for Benthic Species

  • Reconstruct the chronology of invasions of Orconectes rusticus and other nonnative crayfishes into the Great Lakes
  • Use genetic analyses of the regions in Lake Michigan where O. rusticus is displacing O. propinquus
  • Predict the future distribution of O. rusticus in the Great Lakes by comparing the environmental requirements of O. rusticus (especially substrata) with the characteristics of Great Lakes littoral zones
