Control of the Sea Lamprey ('Petromyzon marinus') in Lake Superior, 1953-70.

摘要

The sea lamprey (Petromyzon marinus) gained entrance into Lake Superior in the early 1940’s, and began making drastic inroads on the fish stocks by the early 1950’s. Serious efforts to control the parasite began in 1953 with the installation of electrical’ barriers in streams to block spawning runs. Control measures became much more effective after 1958, when a selective toxicant, the lampricide 3-trifluoromethyl-4-nitrophenol (TFM), was used to destroy larval lampreys in streams.
