Asian carp will certainly survive and most likely thrive if they are able to make their way into Lake Michigan, according to a study released Monday by the University of Michigan. Some researchers had theorized that the invasive species would do well in areas close to the shore where there are more nutrients but might struggle in open water where zebra and quagga mussels — also invasive species — eat most of the plankton that forms the base of the aquatic food chain. But the new study suggests that Asian carp would be able to sustain themselves by feeding on the feces of invasive mussels and other waste products. For Flanagan, the new study reaffirms the importance of Congress appropriating funding to allow the U. The plan involves a series of defenses including a bubble screen, an acoustic deterrent and a flushing lock designed prevent the carp from spreading further. We expect them to start moving on them in September when they return from recess.
New Asian Carp Study Reaffirms Need to Protect Great Lakes
Asian Carp Integrated Control and Containment
First, we will introduce students to the concepts of watersheds, food webs and invasive species. Then we will introduce the Asian Carp, an invasive species that could become a threat to the Great Lakes watershed by traveling up the Mississippi River. Students will fold, match, and color a worksheet that shows an aquatic food web with and without Asian Carp. We will discuss what differences they find and how those differences could have ecological and social effects beyond the scope of the worksheet. Next we will discuss with the students how plants and animals are not static, that is, they can change their strategies to adapt to changes in their environment.
Asian Carp Removal and Monitoring in the Upper Mississippi River
Bighead carp and silver carp Asian carp populations are increasing in abundance and expanding their upstream range within the Upper Mississippi River UMR. However, the detection of young-of—year Asian carp above LD19 indicates that Asian carp populations have reached densities capable of detectable reproduction. To combat this population expansion and decrease Asian carp densities at the established front pools , Quad Cities — Keokuk, IA , IRBS is taking additional measures to monitor, control and manage Asian carp while densities are still relatively low. The removal of Asian carp species by commercial fishers from pools reduces Asian carp densities and minimize their chances of supporting a reproductive population in the Upper Mississippi River. This removal is aided by mark and recapture efforts and hydroacoustic surveys to assess the effectiveness of harvest to reduce Asian carp populations.
Current Asian carp research at MAISRC primarily focuses on preventing their introduction using enhanced bubble curtains and modifications to locks and dams.
