Lake trout historically supported the most valuable freshwater commercial fisheries in North America, but their populations crashed in parts of the Great Lakes during the 1950s and 1960s due to overfishing and invasive species.

A 31-mm sturgeon captured in the Missouri River near Williston, North Dakota, on July 8 using a beam trawl. Sampling efforts occurred in support of a recent inter-agency collaborative drift experiment involving 700,000 sturgeon embryos. This sturgeon will be genetically test to see if it is from those used for the experiment.
