Catfish are making a comeback in the Chicago River.
State Natural Resources officials and “The Friends of the Chicago River” released 30,000 fish into the Chicago River and little Calumet River Tuesday.
According to the Chicago Tribune, the fish release is part of a $300,000 restoration effort, paid for with a grant from the National Fish and Wildlife Foundation Chi-Cal Rivers Fund, to increase the population of catfish in Chicago-area waterways.
Catfish were once native to the Chicago area.
By the end of next year, another 70,000 fish will be released into the rivers.
