1952, Sea lamprey spawnings Michigan streams of Lake Superior. 

 Fish and Wildlife SerVo., Spec. Sci. Rep.: Fish. No. ?0, 

 68 pp. 



Results of surveys of 869 streams in 195o and 178 in 

 1951 (both figures inclusive of tributaries) to ascertain occur- 

 rence of sea lamprey spawning runs and to estimate productive 

 potentials of streams on basis of extent of spawning grounds and 

 larval habitat. Tentative outline is given of control program 

 (based principally on electrical devices and barrier dams) for 

 the 19ij. streams on which control ultimately may prove necessary.

 marinus , in the Lake Huron basin. Trans. Am. FiihT 

 Socj Vol. 81 (1951), pp. 9ii"100. 



Results of examination of 2l5 recently transformed young, 

 29 active feeders from the lake, and 25^7 sexually matiire upstream 

 migrants. Evidence of disease was small. Percentages of para- 

 sitic infestation weres recently transformed young— 2. 3j lake 

 feeders— 3I0O1 sexually mature lampreys--lii,8. Yoimg lampreys 

 harbored nematodes only; last two groups carried acanthocephalans , 

 nematodes., and cestodes. Parasites are considered unimportant as 

 a natural control of the lamprey.

 problem of developing methods of control by mechanical barriers, 

 electricity, poisons, and other means.
