5. Development and Improvement of Electric Shocker. (FA: F-l-R) 



Objectives were to test, design and improve electric shockers, including 

 A. C. andD.C. types, including also battery-operated (portable) apparatus and 

 electric trawl for deep water. 



State Fish Hatchery, Rome; began April 1952, to close March 1955; $5,418; 

 D. C. Haskell, Leader; reports available. 



Address inquiries to: John R. Greeley, as in No. 1 above. 



6. Hudson River Shad Investigation. 



In order to evaluate relative success of reproduction from year to year, 

 annual sampling of young shad is carried on by seining in late summer. 



Lower Hudson River; began July 1948, indefinite; $800; C. E. Heacox, 

 Leader. 



Address inquiries to: John R. Greeley, as in No. 1 above. 



7. Striped Bass Study. (FA: F-IO-R) 



This study will be centered in the Hudson River and Long Island waters, to 

 determine factors affecting maintenance of the resource of striped bass. Through 

 liaison with other Atlantic coast states, many of which are starting similar studies, 

 it is expected that these factors will be studied over the entire region. 



Hudson River and Long Island; began January 1954, indefinite; $23,810 (for 

 1/4 years). 



Address inquiries to: John R. Greeley, as in No. 1 above. 



8. Experimental Carp Control. (FA: F-9-R) 



In a number of selected lakes, tests of the value of controlling carp as a 

 fisheries management practice are being carried on through removal of a part 

 of the carp population and a study of associated species of other fish (including 

 game fish) before and after such operations. Observations on habitat changes 

 associated with removal of carp are included. 



Statewide; hdqrs. Norwich; began June 1953, indefinite; $21,862; H. A. Loeb, 

 Leader. 



Address inquiries to: John R. Greeley, as in No. 1 above. 



9. Studies in Disease Control of Hatchery Fish. 



In order to improve propagation methods, continuous research on control 

 of disease is necessary, including both experimental work and liaison with fish 

 hatchery personnel to diagnose and cure outbreaks responsible for losses. 



Rome Fish Hatchery Laboratory; began 1932, continuing; $12,000; L. E. Wolf, 

 Leader; reports available. 



Address inquiries to: John R. Greeley, as in No. 1 above. 



10. Studies in Nutrition of Hatchery Trout. 



In order to improve propagation methods, continuous research on trout diets 

 and physiology is carried on, including close liaison with fish hatchery personnel 

 concerning problems and practices. 



U. S. Fish and Wildlife Service and Cornell University cooperating; Fish 

 Nutrition Laboratory, Cortland; began 1934, continuing; $9, 500; D. R. Brockway, 

 Leader; reports available. 



Address inquiries to: John R. Greeley, as in No. 1 above, 



11. Lake Ontario Lake Trout Investigation. 



Objectives of the project are to explore possibilities of improving manage- 

 ment of lake trout at eastern end of Lake Ontario, a joint investigation of lake
