This is the irony of the re-emergence of Harmful Algal Blooms on Lake Erie - more #Walleye. More algae means more #zooplankton (and #benthos) which ultimately feeds these fish. They have also been eating Yellow Perch (another desirable, targeted planktivorous fish), and driven down their numbers considerably.

Some people want more fish.
Some people want less harmful algae.
Can't have both.

The push and pull of lake management.

Blooms of #Cyanobacteria pose a significant threat to #freshwater systems including rivers driving both #eutrophication and its dire implications for freshwater species as oxygen availability plummets and also the additional threat posed by #cyanotoxins produced by some Cyanobacteria.

This new research in Scientific Reports takes a #metagenomics and Q-PCR approach to explore the composition of the Cyanobacterial populations and their cyanotoxin production gene in major rivers across the United States (in 2019) and identifies Microcystis as the key toxin producing genus across this study.
