Biologists have found evidence that sturgeon are spawning successfully in the St. Louis River, marking only the second time recently hatched sturgeon have been found there.
A Duluth News Tribune report says fishery biologists with the Fond du Lac Band found a single tiny sturgeon this week that hatched from an egg. The only other time that happened was in 2011, when the same team of biologists found four tiny fish.
John Lindgren is a fisheries specialist with the Minnesota Department of Natural Resources. He says the find is important because it means there's consistent natural reproduction.
The DNRs in Minnesota and Wisconsin used to stock the river with the prehistoric-looking fish from 1983 to 2000, then stopped to see if they could find evidence of natural reproduction.
