ok, I got an email about the research just after posting. Here was the response:
"Good morning!
Thank you for your email. I will pass it along to our scientists. I�m also passing it along to our Fisheries Extension Biologist, Allen Pattillo. Allen is out of the office on vacation at the moment, so he won�t respond immediately, however he can be reached at
[email protected] or 515-294-8616 when he returns.
Have a great day!

A bit more hopeful response here. I will try and contact Allen Pattillo as well. I would suggest another other Iowegians with interest in this topic might contact him as well..
