I spent yesterday learning how to ID Michigan's native freshwater mussels in a free workshop led by the state's top experts - 2 retired dudes sharing their accumulated knowledge of these fascinating animals
DYK mussels use a lifelike lure to attract fish, which are hosts for their parasitic larvae?

🪰 Freshwater Friday - Flat-bodied stone-clingers (Heptageniidae)
Larvae in this family of mayflies have a flattened shape, which is perfect for clinging to rocks in fast-flowing streams.
If you spot them, it’s a good sign of a healthy river.

New study from our lab: Feeding efficiency (trophic impact) of goldfish varies with combinations of thermal & salinity conditions typical of urban ponds in north temperate regions. Salinity enhances efficiency at temperatures below the thermal optimum of goldfish.

The Allegheny Front: Help Wanted - Stop The Spread Of Invasive Round Goby Fish In PA www.alleghenyfront.org/help-wanted-...
Help wanted: Stop the spread of invasive round goby fish in Pa.
The Eurasian round goby is causing big problems in Lake Erie, outcompeting native fish. Pennsylvania is looking to anglers to help stop it from spreading to inland waterways.

Not much is scarier for a #GreatLakes fish than the invasive sea lamprey, sometimes called vampire fish 🧛
But while they're more trick than treat in their introduced range, they're actually threatened in parts of their native range of the Atlantic coasts of Europe + North America - that's scary!

Spooky scary zombie salmon? Pacific salmon don't live long postspawning. While some die immediately, others live briefly + embrace rotting—literally—floating around and deteriorating. As their bodies decay, nutrients return to the environment, even to their future offspring! doi.org/10.1002/fsh....

🐟 “Arnie” the Murray cod (Maccullochella peelii) swam 530 miles upstream. A record journey across Australia’s Murray-Darling rivers. When rivers stay connected. Water flows. Life flows 💪

A freshwater fish named Arnie just swam a record 530 miles, mostly upstream, Australian scientists say
The Murray cod, named Arnie after Australia's recently retired Olympic champion Ariarne Titmus, was first tagged in 2022.
