During spawning, sturgeon lay in groups of two or three-that is, one or two males per female. No nest is built, but the sticky eggs adhere to stones and vegetation. Lake sturgeon may not be harvested because their numbers have dwindled alarmingly-even in the St. Lawrence River where the largest population exists. This fish is considered threatened in New York State. Dark dots represent where actual samples of lake sturgeon were taken.
