Phil Wilink from the Field Museum and I went out to 12th Street Beach last week for a quick survey of the fish in the area. I was amazed to see the banded killifish which is a native Great Lakes fish I have never seen before in my more than 20 years of fishing. The banded killifish is a state threatened species based on Illinois Department of Resources standards which means it is a fish likely to become a state endangered species within the foreseeable future in Illinois. It has most likely suffered because of invasive species like round gobies and alewives dominating the food supply in Lake Michigan. I hope that seeing them near Burnham Harbor is a positive sign for their populations.
I go out regularly with the Great Lakes team to do beach sweeps at 12th Street Beach and never knew this fish was so close!
