I would appreciate if anybody could confirm the fish in the photos by Carlos De la Pena Jr. are bighead carp or not.
He took them during the cleanup of the winter fish kill at McKinley Park lagoon on Tuesday.
It would not be surprising if more bigheads were in that lagoon. Within the past decade three large bigheads have been confirmed there.
If anybody knows the answer about the photos, please post below or e-mail at firstname.lastname@example.org.
Here's De la Pena's note:
Just wanted to fill you in on my discovery this afternoon at McKinley Park on the southside of Chicago.
There was apparently a major winter fish kill at McKinley Park Lagoon!
Today I assisted a gentlemen that works for the a company called Aramark, his job entitles him to remove dead fish and debris from the shoreline of several city park lagoons.
I noticed that there were several Large dead Asian Bighead carp along the shoreline and I immediately flag him down and told him that those are invasive species. I recommend that he inform his boss so that they can contact the IDNR. I counted about five 25+ lb Asian bighead carps along the northern shoreline near the fishing pier.
I tried to call the IDNR but I didn't get an answer from those guys and I also left a voice message for Bob Long Jr at the Park District office informing him of what I witnessed.
