Both adults build a circular nest out of rocks, & guard their young. The young migrate to the ocean to begin their parasitic ways.

The only other NJ lamprey is the American Brook Lamprey. It is much smaller than the S.Lamprey, and totally non parasitic. Spends its entire life in freshwater streams. These are the ones that anglers harvest as primo walleye bait.

good info, thanks Mark
