Silver Lamprey

Icthyomyzon unicuspis

Silver Lamprey occurs as ammocoetes in medium-sized and larger streams with clean sand and gravel, and parasitic adults travel to a wider range of waters. It is native to six north and western watersheds and has also become established in the Upper and Lower Hudson. Improved sampling techniques may explain the greater number of collections made in more recent surveys.
