5. Tagging Program, Lake Erie. 



A tagging project is under way to study migratory habits of Lake Erie specie: 

 including blue pike, yellow pike, yellow perch, and white bass. 



Pennsylvania waters of Lake Erie; began August 1953, continuing; $1, 000; 

 Alfred Larsen, Leader. 



Address inquiries to: Gordon L. Trembley, as in No. 1 above. 



6. Evaluation of Waste Materials of the Marine Clam Processing Industry in 

 Hatchery Diets. 



The objective is to determine the value of marine clam visceral trimmings 

 as a fish food. Growth rate, color changes, mortality of fish and feeding costs 

 are being studied. Clam trimmings are used alone and in conribination with other 

 dietary mixtures. Trout of various sizes are being used presently as test fish. 



Fisheries Research Laboratory, Bellefonte; began April 195 3, to close 1955; 

 $500; Arthur D. Bradford, Leader. 



Address inquiries to: Arthur D. Bradford, Pathologist, Fisheries Research 

 Laboratory, Pennsylvania Fish Commission, Bellefonte, Pa. 



7. Biological Survey of Streams. 



Objectives are to evaluate the biological, physical and chemical factors of 

 streams, and to obtain basic information to assist in the management of streams. 

 The primary purpose is to determine to what extent major streams shall be 

 classified as to trout or warm-water areas. Special emphasis is placed on fish 

 populations, temperatures, bottom-food organisms, flow and pollution. 



Statewide; began 1932, continuing; $15,000; Otis Robbins, Jr., Leader; 

 reports available. 



Address inquiries to: C. R. Bxiller, Chief Fish Culturist, Fisheries Re- 

 search Laboratory, Pennsylvania Fish Commission, Bellefonte, Pa. 



8. Acquisition and Construction of Public Fishing Lakes. (FA: in part) 



Objectives of the project are to purchase existing lakes and lake sites and 

 to build dams, thus providing additional acreage of public fishing lakes. An 

 attempt is made to locate lakes near centers of heavy human populations. During 

 1953, 3 dams to impound 86 acres of water were constructed and one 18-acre 

 pond was purchased. 



Statewide; began 1952, continuing; T. F. O'Hara and Cyril G. Regan, 

 Leaders. 



Address inquiries to: T. F. O'Hara, Chief Engineer, Fisheries Research 

 Laboratory, Pennsylvania Fish Commission, Bellefonte, Pa.

1. Bio-assay Studies of Industrial Wastes. 



Objectives of the project are to evaluate the lethality of industrial wastes, 

 their components and other water pollutants to fish. The evaluation, as deter- 

 mined by bio-assay procedures, offers a reasonable judgment tool in administer- 

 ing effective stream pollution abatement. 



Fisheries Research Laboratory, Bellefonte; began November 1949, indefi- 

 nite; C. S. Myers and Thomas lezzi. Leaders; reports available. 



Address inquiries to: Dr. C. S. Myers, Department of Health, Bureau of 

 Sanitary Engineering, Harrisburg, Pa.
