PROGRESS IN BIOLOGICAL INQUIRIES, 1931 443 



bureau's biological or experimental stations or at universities. Only 

 a small administrative staff in the office of the chief of the division is 

 located at Washington, D. C. A half dozen or so investigators 

 whose duties require their location there are accommodated in the 

 new laboratories of the Department of Commerce building. 



The scientific projects cover three major fields: Marine and fresh- 

 water commercial fisheries investigations, investigations pertaining 

 to game fishes, and shell-fisheries investigations. Commercial fishery 

 investigations are organized under six distinct sections, each with a 

 responsible technical head. The North Atlantic fishery investiga- 

 tions, directed l)y O. E. Sette, are conducted fi'om headquarters lo- 

 cated at the Harvard Biological Institute, Cambridge, Mass., the 

 Woods Hole Biological Laboratory serving as headquarters during 

 the summer season only. The South Atlantic staff is housed at the 

 Fisheries Biological Laboratory, Beaufort, N. C, under the direction 

 of Dr. H. F. Prytherch. Investigations in the Gulf, directed by Dr. 

 F. W. Weymouth, chiefly concerned with the great shrimp fishery, 

 are conducted from headquarters provided by the Conservation De- 

 partment of Louisiana at New Orleans. Fishery investigations in 

 interior waters, under Dr. M. M. Ellis, including studies of pollution 

 of the Mississippi River system and the propagation of fresh-water 

 pearl mussels, are facilitated by laboratories provided by the Uni- 

 versity of Missouri, Columbia, Mo. Great Lakes fishery investiga- 

 tions, directed by Dr. John Van Oosten, are centered at the Uni- 

 vei-sity of Michigan, Ann Arbor. The staff for the Pacific coast and 

 Alaska fishery investigations, directed by Joseph A. Craig, is housed 

 at the new Fisheries Biological Laboratory, Seattle, which was com- 

 pleted during the past year and is adjacent to the campus of the 

 University of AVashington. 



Although the division of scientific inquiry conducts no investiga- 

 tions directly concerned with angling, a considerable amount of atten- 

 tion is given to problems of interest to the angler inasmuch as they 

 concern the food and game fishes of interior waters, their culture, 

 distribution, and their planting in depleted or formerly barren 

 waters. 



These investigations are of various types. The original distribu- 

 tion and taxonomic distinctions of the Salmonidse of New England 

 have been investigated by Dr. W. C. Kendall. While the chief in- 

 vestigator in aquiculture, Dr. H. S. Davis, is located in Washington, 

 D. C, studies under his direction in the interest of fish culture, 

 pathology of fishes, fish nutrition, and selective breeding are con- 

 ducted at the Fisheries Biological Laboratory, Fairport, Iowa, at 

 the experimental trout hatchery, Pittsford, Vt., at the experimental 

 trout and bass station at Leetown, W. Va., and at certain cooperative 

 stations where facilities are provided. Headquarters for trout-cul- 

 tural investigations and stream surveys conducted by Dr. A. S. Haz- 

 zard in the national parks and forests of the Rocky Mountain region 

 are maintained at the University of Utah, Salt Lake City, while Cali- 

 fornia trout investigations carried on by Allan C. Taft are centered 

 at Stanford University. 



As a by-product of studies on the life history of fishes in Chesa- 

 peake Bay, John C. Pearson produced a popular Fishery Circular 

 on the sport fishing in those waters.
