1 – Making Great Lakes soda may help control Asian carp.
Researchers say adding carbon dioxide gas to water, a process similar to making carbonated soda, could help control the movement and behavior of invasive carp in the Great Lakes.
Scientists with the University of Illinois and the U.S. Geological Survey tested the effectiveness of infusing water with carbon dioxide gas to discourage movement of the carp. Both carp species avoided CO2-infused water in a research pond in Wisconsin.
The study’s lead author says the responses provide evidence that CO2 could be used as a tool to deter the movement of bighead and silver carp.
Scientists say further tests are needed before CO2 can be used in Asian carp management.
The next research step is to test the usefulness of CO2 gas in controlling carp movement in a natural river.
2 – Visit the Shiawassee National Wildlife Refuge, and don’t forget your cell phone.
The refuge, located in Saginaw County, is putting on a Cell Phone Photography Contest.
The contest will be judged by adult and youth age groups.
Each group can submit photos that depict wildlife, or plants and landscapes.
The public will vote online for their favorite photos in the two categories from July 24-30.
Certificates and prizes will be awarded.
– Mr. Great Lakes is heard at 9 a.m. Fridays in Bay City, Michigan, on Delta College Q-90.1 FM NPR.
