CHILTON – The DNR’s top sturgeon biologist resigned Thursday, the same day he was found guilty in Calumet County of obstructing a conservation warden during an investigation into the illegal bartering of sturgeon eggs for caviar.
Ryan Koenigs pleaded no contest to the charge and was fined $500, according to court records.
DNR spokesperson Sarah Hoye said he resigned from the agency Thursday morning.
Koenigs also was convicted last month in Winnebago County of resisting a conservation warden and fined $50, according to court records.
Koenigs was accused of taking sturgeon eggs from a state research lab with a former DNR biologist after working hours and having them made into more than $100,000 worth of caviar for friends, processors and DNR employees, according to a criminal complaint filed in Winnebago County.
