1. A Creel Census on Wononskopomuc Lake 



The objective is to determine the species of trout best suited for stocking 

 in Connecticut trout lakes, the age class best suited for stocking and the 

 period or periods most effective for stocking. 



Equal numbers of brook, brown, and rainbow trout, both yearlings and 

 2-year-olds are stocked in Wononskopomuc Lake. The creel census gives 

 approximately 80 percent coverage of the lake. Brown trout have provided the 

 highest returns to the rod for the past 3 years. Recovery has varied from 60 

 to 80 percent. 



Northwestern Connecticut; began December 1953, to close November 1957;

 Board of Fisheries and Game, State Office Building, Hartford, Connecticut. 



2. Yellow Pike -Perch Fishery in Lake Lillinonah 



The objective is to establish yellow pike-perch in the new 1, 900-acre im- 

 poundment on the Housatonic River in western Connecticut. 



Approximately 20, 000, 000 pike-perch eggs were obtained from New York and 

 Ohio. These eggs were hatched in the State fish hatchery in Burlington and 

 9, 800, 000 day-old fry were stocked in Lake Lillinonah. The extent of survival 

 has not been determined, but six pike-perch taken during sampling operations 

 in October averaged 9^ inches long. 



Western Connecticut; began November 1955, to close November 1958; $4, 000; 

 James P. Galligan, Leader. 



Address inquiries to: James P. Galligan, Supervisor of Fisheries Man- 

 agement, State Board of Fisheries and Game, State Office Building, Hartford, 

 Connecticut. 



3. Investigation of the Candlewood Lake Rainbow Trout Population 



The objective is to determine the recovery rate of stocked adult rainbow 

 trout and the contribution of other sources of rainbow trout to the fishery. 



Three thousand 2-year-old rainbows were tagged and stocked last year. 

 In addition to the tagging of adults, all rainbows of hatchery origin have been 

 fin-clipped. This includes yearlings from the federal hatcheries for lake 

 stocking and state fingerlings stocked in two tributary streams. By identifying 

 every stocked rainbow with a mark or tag over a period of four to five years 

 we can determine to what extent the naturally spawned wild trout contribute to 

 the fishery. Also to be determined is the numbers of fingerlings and yearlings 

 appearing in the catch. 



Western Connecticut; began June 1955, to close 1959-1960; $5, 000; James P. 

 Galligan, Leader. 



Address inquiries to: James P. Galligan, as in No. 2 above. 



4. Control of Submerged Vegetation 



The objective is to control submerged vegetation in ponds where the density 

 of these "water weeds" makes fishing or boating difficult or impossible. 



Submerged vegetation is treated with 5 parts per million of sodium ar- 

 senite. This is sufficient to kill most submerged weeds with the exception of 

 Myriophyllum, sp. , which is treated with 7 parts per million. 



Statewide; began May 1956, closed July 1956; $3,788; Cole W. Wilde and 

 James P. Galligan, Leaders. 



Address inquiries to: Cole W. Wilde, as in No. 1 above.
