In the news: Carp explanation may be a fish story

Posted August 17th, 2010 in Aquatic Invasive Species, News

From the Milwaukee-Journal Sentinel:

In the wake of a government news release that pointed a finger at humans for planting an Asian carp near Lake Michigan, facts are coming to light that indicate Illinois officials may have stretched their own science to sell a whopper of a fish tale.

When netting crews hunting for Asian carp above an electric barrier on the Chicago canal system in June pulled a three-foot long, 20-pound mature bighead carp from Lake Calumet – just six miles south of Lake Michigan – the question was: How did it get there?

If it swam on its own, that would spell trouble for Lake Michigan because it could indicate that the electric fish barrier about 35 miles downstream from the lake was not doing its job, and more fish had perhaps breached this last line of defense.

If it were determined that the fish got there with human help, then it could more easily be explained as an isolated find, and not evidence that additional steps should be taken on the canal system to protect the Great Lakes. Read more.

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.

Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.

Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.

Managers and researchers can be faced with a need to classify the risk of new crayfish invaders. Rapid assessment tools, such as the Science-based Tools for Assessing Invasion Risk (STAIR), can assist in this process by providing a streamlined framework for analysis and decision-making.

Join us for an ICC webinar with John Bieber from Loyola University Chicago to learn how rapid assessment tools are used to classify invasive species risk and how STAIR can support invasive crayfish management.
