Kootenai River White Sturgeon

A recent study by the U.S. Geological Survey found that the eggs of endangered Kootenai River white sturgeon are less likely to hatch on some of the surfaces that have been made more common by human changes on the river.

The white sturgeon (Acipenser transmontanus) was once common in much of North America. White sturgeon in Idaho and Montana’s Kootenai River basin were listed as endangered in 1994.

The publication, "Hatch Success of White Sturgeon Embryos Incubated on Various Substrates," USGS Report Series 2013-5180, by Michael J. Parsley and Eric Kofoot, is available online.
