METHOD FOR CONTROLLING SEA 

 LAMPREYS (PETROMYZON MARINUS) 

 Application Serial Number 583,889 

 May 9, 1956 



Control of lamprey populations by 

 the chemical treatment of streams 

 with 0-ethyl-S-pentachlorophenyl 

 thiolcarbonate, a selectively toxic 

 agent. Controlled applications permit 

 destruction of all larval lampreys 

 in a watershed without causing sig- 

 nificant harm to other aquatic life.

METHOD OF CONTROLLING SEA 



LAMPREYS WITH HALOGEN 



NITROPHENOLS 



U.S. Dept. Int. Case No. FWS-313 



July 13, 1956 



Control of lamprey populations by 



the chemical treatment of streams 



with various halogen mononitro- 



phenols. These selectively toxic 



agents destroy the larval stage of 



the sea lamprey without causing 



significant harm to other aquatic 



life.
