Encroaching Carp, Barrier Delays Threaten Great Lakes Ecosystem
For decades, four species of invasive carp have been working their way toward the Great Lakes. On their way, they’ve left a trail of decimated native fish populations and injured boaters.

Alternatively: Why you should give a carp about the recent news that juvenile invasive carp have been found closer to Lake Michigan and the stop-work order on the Brandon Road barrier.

Harmful algae blooms might not just cause harm in the water. Researchers are working to understand how the toxins produced in these blooms can become airborne and impact people’s health - something boaters and anglers around Lake Erie call "August cough" www.cbc.ca/news/canada/...
Scientists near Lake Erie are studying the health impacts of airborne algae | CBC News
So far, the American-led research has tracked roughly 200 people connected to Lake Erie coastal communities.

Wandering tattler?? I'm convinced that ornithologists are just trolling when it comes to bird names www.detroitnews.com/story/news/l...
Wandering tattler makes first confirmed Michigan appearance
These small gray birds rarely venture east of the Rocky Mountains. Then one showed up on the Lake Michigan shoreline in Ottawa County.

Caught this baby trying to shove its whole head into its parent's crop.
(I would really have liked to spend more time with them but apparently @ferries.wsdot.wa.gov wants you to "drive your car off the ferry" without "holding everyone up." Even for baby cormorants!)

Female Coho (Oncorhynchus kisutch) have returned to the #Salmon River on the #Oregon coast where I am visiting. Thought she would be appropriate for today's #SundayFishSketch. Hoping to participate more as we turn to autumn. #fish #illustration

This year's crop of wild rice/manoomin in Wisconsin has been better than average, due to both stable weather conditions during the growing season and the efforts of tribes to restore and protect wild rice-growing waters www.wpr.org/environment/...
Wisconsin's wild rice harvest is expected to be up this year
Wild rice, or manoomin in the Ojibwe language, is culturally significant to northern Wisconsin tribes, and Wisconsin regulators are anticipating an increased wild rice harvest this year.

In some areas of Lakes Michigan and Huron, almost no whitefish hatchlings have survived to adulthood for nearly two decades. Now, state and tribal scientists are collecting spawning whitefish - a kind of Noah's Ark attempt to save several distinct genetic strains

With no time to spare, Michigan hatches a Great Lakes whitefish rescue plan - Bridge Michigan
With little time left to avert a population collapse, officials plan to pluck whitefish from the mussel-infested Great Lakes and raise their offspring in hatcheries.
