NEW YORK (Cont. ) 



populations of yellow perch and other species undesirable for trout management. 

 By use of barrier dams the area is subdivided so as to be handled by rotenone 

 treatment over a 3-year period. Effects are being evaluated. 



Franklin County; began April 1952, to close March 1956; $11,253; R. G. 

 Zilliox, Leader. 



Address inquiries to: R. G. Zilliox, as in No. 16 above. 



18. Adirondack Trout Restoration Project. 



This is a combination of research and management work to develop methods 

 for reclaiming Adirondack trout ponds and lakes for trout production. Checks of 

 efficiency of destruction of undesirable fish following rotenone treatment are 

 made, also creel census of trout fishing in several waters following trout stocking. 



Northern New York; began 1950, indefinite; $17, 000; R. G. Zilliox, Leader; 

 reports available.

19. Control of Light Intensity to Induce Early Egg Production in Hatchery Trout. 



The light cycle is controlled through equipment to light breeder ponds to 

 lengthen the day and equipment to darken the ponds and thus shorten the day. By 

 experimentation in operation of this equipment brown and brook trout have been 

 made to produce eggs much earlier than usual. 



Randolph and De Bruce fish hatcheries; began 1950, indefinite; $100; O. R. 

 Kingsbury, Leader; reports available.

20. St. Lawrence River and Lake Ontario Smallmouth Bass Investigation. 



The purpose of this investigation is to obtain facts basic to management of 

 the important bass resource of the large area of eastern Lake Ontario and upper 

 St. Lawrence, following up through tagging and migration studies previous work 

 which indicated localized nature of bass populations. 



Lake Ontario and St. Lawrence River; began 1941, indefinite; $1,000; D. G. 

 Pasko, Leader; reports available. 



Address inquiries to: D. G. Pasko, Senior Aquatic Biologist, Conservation 

 Department, 95 Public Square, Watertown, N. Y. 



21. Management of Game Fish and Bait Miruiows in Farm Ponds. (FA: F-4-R) 



This project, handled through Cornell University (contract basis), is designed 

 to test and improve management methods in trout ponds, ponds stocked with warm- 

 water game fish, and bait minnow ponds. Work on trout ponds includes evalua- 

 tions of experimental stocking rates, determinations of angling yield and natural 

 mortality, and investigations of the relative longevity of various trout hybrids and 

 late-maturing strains of trout. Research on warm-water ponds is concerned 

 with evaluations of various stocking ratios of largemouth bass and bluegill sunfish, 

 of ponds stocked with bass and bluegills plus yellow perch or chain pickerel, and 

 of ponds stocked with channel catfish alone. Objectives of the minnow pond invest! 

 gations are to determine the production, growth, and optimum stocking rates for 

 golden shiners, fathead minnows, common suckers, and silvery minnows in New 

 York, and to investigate the feasibility of planting green and eyed sucker eggs in 

 farnn ponds.
