2. Studies of Diseases of Game and Pan Fish Having a Possible Viral Etiology, 

 Using Cell Cultures in vitro Originating from Normal Fish Tissues 



The objectives are: (1) To develop techniques for the production of cell 

 cultures in vitro originating from normal fish tissues; (2) to attempt to 

 isolate and study agents from diseased fish showing lesions of probable viral 

 etiology; and (3) to make epizootiological studies of diseased fish populations 

 for the purpose of eventual disease control.

1. Pond and Lake Survey 



This project is a survey of representative standing inland waters to evalu- 

 ate them for management needs.

 Leader; reports available. 



Address inquiries to: Saul B. Saila, Department of Zoology, University 

 of Rhode Island, Kingston, Rhode Island. 



2. Striped Bass Physiological Investigations 



The objectives are to establish a local race of striped bass in Rhode 

 Island's coastal waters and attempt to establish striped bass in fresh and 

 brackish water ponds. Studies include: (1) The effects of fish pituitary in- 

 jections on sexual development, (2) the effects of certain synthetic hormones 

 on salt retention and the ability to survive transfers from a more to a less 

 concentrated medium, (3) eifects on movements of migrant fish held beyond 

 the normal migration period, (4) effects of thyroid inhibitor on migration 

 and movement, and (5) a study of maximum temperature tolerance in the jj 



striped bass. 



Headquarters - University of Rhode Island; began March 1956, to close

3. Construction and Improvement of Fishing Areas on State -Owned Lands J 



The objective is to improve sport fishery facilities on state-owned or 

 controlled lands by construction of ponds, stream improvement structures, 

 parking lots, stream-side paths, and other facilities. 



Statewide; began December 1953, indefinite; $23,500; Chester Whaley, 

 Leader; reports available.
