Abstract

The parasitic sea lamprey, Petromyzon marinus, has in recent years spread throughout Lakes Huron and Michigan and is now firmly established in these waters (Applegate, 1949, Mich. Cons., 18 (4): 13-15). Coincident with their spread, the abundance of lake trout, Salvelinus namaycush, has declined in both lakes (Hile, 1949, Trans. Amer. Fish. Soc., 76 (1946): 121-147) and the lake trout as well as other species of fishes are showing an increase in scarring from lamprey attacks. For Lake Michigan the analysis of fishermen's questionnaires gave an increase in percentage by weight of lamprey-scarred lake trout from 31 percent in 1947 to 41 percent in 1948. The sea lamprey is now spreading through Lake Superior, the last of the Great Lakes containing a large population of lake trout.
