For decades, scientists estimated lake sturgeon lived for 150 years. New evidence suggests some Great Lakes fish may reach more than 400 years

• Their lives can stretch far beyond those of most freshwater fish, but just how far has remained uncertain.
• New research now suggests that some may survive for more than four centuries.
