Sea lamprey (Petromyzon marinus) ammocoetes collectected from 18 locations within Lake
Superior were eIectrophoretically analyzed for genetic variability at 25 enzyme loci. Analysis
by F statistics and x2 tests indicated that a significant degree of population structuring occurs
among lampreys from Lake Superior. Cluster analysis of genetic distances generally grouped
collections that were in close geographical proximity to each other. A weak but significant
correlation was detected between genetic and geographic distances. It was concluded that
multiple populations of sea lamprey occur within Lake Superior. If this is the case, then sea
lamprey control emphasis might shift from individual streams to population regions to minimize
the rate of reestablishment subsequent to chemical treatment. It may also be wise to
avoid the planting of fish species with migratory habits so as to prevent the passive transport
of adult lampreys out of their population areas.
