What’s the deal with Lake Michigan’s chinook salmon population?
The Michigan Department of Natural Resources has heard a lot of rumors and confusion about why the salmon fishing in Lake Michigan is so inconsistent at times.
So they’ve put together a video to explain what’s actually going on. In the end, it all really ties into the invasive zebra and quagga mussel populations in the lake.
What a bizarre situation considering the chinooks were brought in to control an invasive species, but now another invasive species is helping wipe them out.
Because the salmon don’t eat anything other than the alewives, this means the fishing is always likely going to be tied to how the alewives are doing, for better or for worse.
Unfortunately, because the roots of this stretch back over 50 years, there’s no way anyone could have predicted it. Let’s just hope this can be used as an example to take extra steps to avoid other invasive species like Asian carp from reaching the lake.
Who knows how things could be further thrown for a loop if more non-native animals get into the lake?
