Weekly News Roundup: Zebra Mussels, Asian Carp, and More

Hey everyone! Here are some of the things happening in Great Lakes conservation from this past week:

The Columbus Dispatch reports scientists are using blood samples from nesting chicks and eggs to study the presence of metal and chemical contamination in the Great Lakes. The samples are collected without harm to the birds. The researchers are also studying the birds’ nesting pattern to examine how these pollutants impact behavior and mortality.

The Associated Press reports that the U.S. Court of Appeals has dismissed a case brought by 5 Great Lake states against the U.S. Army Corps of Engineers and Chicago’s Metropolitan Water Reclamation District. The suit asked that physical barriers be installed to keep Asian carp out of the Great Lakes watershed. The court felt the states have not shown the ineffectiveness of currently used methods, such as electric barriers, screens, and poisons, reports the Northeast Ohio Media Group. Meanwhile, the Detroit Free Press reports that the two sides may be able to find some common ground on short-term solutions.

Researchers believe that invasive species, such as Zebra mussels, quagga mussels, and round gobies have played a larger role in altering Lake Erie’s zoobenthic community than pollution has, according to Phys.org. Scientists examined how the native communities have declined or recovered through time in relation to the severity of each stressor.

Public Radio International reports that a plan to develop offshore wind energy in Lake Erie is losing momentum. The plan, proposed by the Lake Erie Energy Development Corporation, has come up against concerns over the turbines potential impact on migratory birds, as well as opposition from people with lakeshore property views.

This Sunday will be the 25th annual Lake Superior Day, according to the Northland News Center. Lakeshore communities in both the U.S. and Canada will hold events and festivities in appreciation for the lake and its importance to local economies, ecosystems, and lifestyles.

The Wisconsin Department of Natural Resources released its most recent Lake Michigan fisheries plan to the public, reports the Milwaukee Journal Sentinel. The plan, revised every ten years, intends to preserve Lake Michigan’s sport fishing, commercial fishing, and overall ecosystem health.
