| Despite meeting Clean Water Act mandated pollution targets for more than a decade, a new study shows Lake Erie is still fundamentally unhealthy. The Nearshore and Offshore Lake Erie Nutrient Study concludes this month after a year of research headed by principal investigator Chris Pennuto, a scientist at the Buffalo State College..

Despite years of phosphorus controls, Lake Erie remains unhealthy
Herring could help stabilize Great Lakes food webs
| As Great Lakes food webs collapse under the pressure of invasive species, some researchers say reviving a declining native fish could restore stability. Lake herring (Coregonus artedii), or “ciscoes,” were once a tremendously prolific fish in the Great Lakes and were prey for larger species. However, a number of factors have..

New York Sea Grant study investigates VHS transmission
| It’s non-treatable, widespread, and considered one of the most significant threats to Great Lakes fish. The viral hemorrhagic septicemia virus eats away the cells that line blood vessels in fish, leading to hemorrhaging, anemia, and other symptoms. The devastating virus has now been detected in 28 fish species located across all..

U.S. researchers lend a hand to Guatemala’s Lake Atitlán
| Lake Atitlán has been plagued by wastewater and watershed runoff for years, prompting the Global Nature Fund to dub it the “Threatened Lake of the Year” in 2009. The lake, located in the Guatemalan Highlands, is experiencing rapid growth of cyanobacteria, as well as other bacteria including Escherichia coli and Giardia. This..

Purdue researchers explore climate change’s impact on Lake Michigan fish
| A robotic submarine deployed in Lake Michigan will help Purdue University researchers study how climate change could be impacting the survival of young fish vital to the lake’s ecosystem. The Purdue researchers are studying the larvae of yellow perch and alewives in nearshore waters along the lake’s southern tip, near Michigan..
