Abstract


We reviewed historical records and observations of the Silver Lamprey (Ichthyomyzon unicuspis) in the Hayes River in the Hudson Bay watershed. New records are presented from the Seeber River in the upper Hayes River system that extend the distribution of the Silver Lamprey in northern Manitoba. A new designatable unit for the Silver Lamprey, the Southern Hudson Bay–James Bay, is proposed.
