Describes the origin and organiza-

 search on and control of the sea lamprey 

 and (2) coordination of fishery research 

 on the Great Lakes; and reviews early

 Great Lakes. In Our endangered wild- 

 life, p. 23-24. Nat. Wildl, Fed., Wash-

Review of effects of sea lamprey 

 predation which has brought the lake 

 trout to near extinction in Lakes Huron 

 and Michigan and warning of impending 

 collapse in Lake Superior if lamprey 

 control is not achieved soon.

1957. Recent changes in the deep-water fish 

 populations of Lake Michigan. Trans. 

 Amer. Fish. Soc. 86:393-408. 



The invasion of the sea lannprey 

 precipitated a series of sweeping 

 changes that are still in progress. 

 First came the destruction of stocks of 

 lake trout and burbot, and with it an 

 end of predation by these fish on smaller 

 species, principally the bloater (a cisco) 

 and cottids. At the same time lampreys 

 were forced to turn to the larger 

 species and individuals of ciscoes or 

 chubs as food. As a result, bloaters 

 (and presumably cottids also) increased 

 in abundance and larger chubs grew 

 scarce. By 1954-55, the abundance of 

 bloaters was 347 percent but that of 

 large chubs (10 inches or longer) only 

 37 percent of that in 1930-32 when an 

 earlier survey was made.

1958a. Attack on the sea lamprey. Mich. 

 Conserv. 27(3):21-27. 



Reviews development of the sea 

 lamprey problem in Lakes Huron and 

 Michigan; stresses the evidence that the 

 lamprey alone brought collapse of the 

 lake trout fishery in these Lakes; and 

 warns of possible disaster in Lake 

 Superior. A review is given of the life 

 history of the sea lamprey and of re- 

 search to develop control methods. 

 The development and experimental use 

 of selective toxicants are emphasized.

1958b. Lake trout and sea lamprey. Minn. 

 Conserv. Volunteer 21(126): 18-23. 



Brief statement on the penetration of 

 the sea lamprey above Niagara Falls 

 and its destruction of lake trout stocks 

 in Lakes Huron and Michigan is followed 

 by a more detailed account of the 

 lamprey's spread and damage to the 

 fishery in Lake Superior. Development 

 of control methods is reviewed from
