Lake Superior 'love nest' aims to save sturgeon population

January 15, 2009 - MPR’s Bob Kelleher reports that efforts to help Lake Superior sturgeon become self-sustaining is entering a critical phase. Lake Superior sturgeon were nearly wiped out in the big lake about a century ago. In the 1980's, wildlife officials began restocking sturgeon. Those fish are just now reaching the age to reproduce - but they don't have a good place to do that. Crews have been busy this winter, trying to build the perfect sturgeon love nest.
