the deepwater fishes of that Lake. Particular 

 attention was given to progressive changes in 

 Cisco stocks, the expansion of alewife stocks, 

 and the distribution and habits of larval fishes . 

 Limnological observations also were resumed. 



An important phase of research on 

 coregonids has been the artificial rearing of 

 young of known parentage at the Biological Sta- 

 tion in Northville (a former Federal hatchery 

 near Ann Arbor). The project was set up in an 

 attempt to find characters for the field identifi- 

 cation of young ciscoes (separation by species 

 usually is impossible at lengths less than 7 

 inches). The success in rearing was surpris- 

 ingly good, and much valuable information was 

 accumulated, but attainment of the original goal 

 seems unlikely. The station was closed in early 

 1964. 



Environmental research on the Great Lakes 

 has been handicapped by the lack of a specially 

 designed and equipped limnological vessel. 

 Staff members of the Environmental Program 

 have worked regularly with fishery research 

 programs and have obtained extensive ma- 

 terials and data from the fishery research 

 vessels. From this cooperative arrangement 

 have come numerous and significant advances 

 in knowledge and understanding of the physical 

 and chemical characteristics of Great Lakes 

 waters, currents and seiches, plankton, bottom 

 fauna. . . . The joint study of the fisheries and 

 limnology of Lake Erie is proving most valu- 

 able to the environmental unit and the Lake 

 Erie staff in demonstrating better the effects 

 of the increasing pollution of the Lake. 



The tabulation of statistics on production of 

 all species and on catch, effort, and catch per 

 unit of effort for principal species in the dif- 

 ferent areas (statistical districts) of the Great 

 Lakes has continued uninterrupted. The Bio- 

 logical Laboratory at Ann Arbor now carries 

 out this work for seven States; the eighthState 

 and the Province of Ontario compile their own 

 records by procedures developed in the 

 Laboratory. These statistical records are pro- 

 viding increasingly valuable background for the 

 expanding biological researches. 



PUBLICATIONS BY STAFF MEMBERS 



The following list includes the principal 

 publications of staff members of the Bureau of 

 Commercial Fisheries Biological Laboratory 

 in Ann Arbor. Ornitted have been papers re- 

 sulting from work not associated with Great 

 Lakes research, reviews, and numerous proc- 

 essed memoranda and informational releases 

 of only temporary value, prepared for admin- 

 istrative use, or given restricted distribution. 

 The list does include a number of publications 

 of a popular character prepared for the infor- 

 mation of the general public and the fishing 

 industry; most of these popular articles con- 

 tain illustrative original materials drawnfrom 



the Great Lakes files or are summaries of 

 longer papers issued in scientific publications 

 not generally accessible. 



Reports on researches connpleted under con- 

 tract are listed here if staff members of the 

 Laboratory participated closely in the planning 

 and conduct of the study and the preparation of 

 the final report. Reports on contract research 

 completed more or less independently of the 

 Laboratory are listed in the later section on 

 publications by associated scientists.

 central Lake Huron. In Proc. 7th Conf. 

 Great Lakes Res., p. 45-53, Univ. 

 Mich., Inst. Sci. Technol., Great Lakes 

 Res. Div., Publ. 11. 



Contains data on temperature, pH, 

 conductivity, and concentrations of Na, 

 K, Ca, CI, SO4, Si02, and dissolved 

 oxygen off the mouth of Saginaw Bay 

 and along a transect from Harbor Beach, 

 Mich., to Goderich, Ontario, June- 

 October 1956. Chemical composition did 

 not vary with season or depth. Outflow 

 from Saginaw Bay sometimes caused 

 large increases in concentrations of 

 chemicals in surface waters.

 chemical into streams for control of sea 

 lamprey. Progr. Fish-Cult. 24(4): 190-

Three lightweight, readily portable 

 metering devices were developed for 

 application of selective larvicides in 

 small streams--gravity feeder, fuel- 

 pump feeder, and electric-pumpfeeder. 

 The construction and use of each type 

 are described; photographs of the de- 

 vices are included.
