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.

The push and pull of lake management.
