brook trout (Salvelinus fontinalis). An attempt is being made to deternnine 

 when the host first normally acquires the infection, and whether the fish used 

 in the stocking progrann harbor the parasite. If it is found that the fish acquire 

 the infection prior to being released, the present hatchery practices might 

 possibly be altered so as to produce P. agiibernaculum-free fish.

An Investigation of Landlocked Salmon in the Fish River Chain of Lakes 



This project is designed to gather information on reproduction, migra- 

 tion, early life history, age and growth, and survival of stocked hatchery 

 salmon and will contribute to better management of this species in the study 

 waters and statewide. Trap nets have been operated during the spawning 

 season on a major spawning thoroughfare to obtain detailed data on the spawn- 

 ing migration, reproduction, and characteristics of the spawning run. Scale 

 samples have been collected from the spawning run and by creel census to 

 evaluate age composition and growth characteristics. All hatchery salmon 

 stocked in the Chain of Lakes will be marked for a 3-year period. Evalua- 

 tions of the contribution of stocked fish to the salnnon fishery will be made by 

 creel census, voliantary returns and test netting.

 close June 1958; $2,000; Kendall Warner, Leader; reports available.

An Investigation of the Fresh-water Fisheries of Mount Desert Island 



The objectives are: (1) To re-establish an alewife population in Long Pond, 

 Mt. Desert, by stocking ripe adults. The progeny (of stocked spawners) re- 

 turning as adults are being counted. (2) To study returns to the creel, sur- 

 vival, and spawning habits of marked hatchery-reared brook trout and lake 

 Atlantic salmon by stream trapping and creel census. 



University of Maine cooperating; Hancock County; began May 1950, 

 closed December 1956; $2, 500; Keith A. Havey, Leader; reports available. 



Address inquiries to: Keith A. Havey, 31 Center Street, Machias, Maine. 



Preliminary Investigations of Anadromous Brook Trout Populations in Maine 



The objective is to determine the magnitude, distribution, and character- 

 istics of anadronnous brook trout populations in coastal Maine. Electro- 

 fishing and permanent two-way fish traps are being utilized to conduct the study. 



University of Maine cooperating; eastern and southern Maine; began April 

 1956, to close December 1960; $3,000; Keith A. Havey, Leader. 

 Address inquiries to: Keith A. Havey, as in No. 6 above. 



Statewide Lake and Stream Investigations 



The objective is to evaluate basic physical, chemical, and biological 

 characteristics of Maine lakes and streams including: (a) Physical and 

 chemical characteristics of Maine lakes and streams in relation to species 

 suitability and productivity, (b) population studies of lakes and streams, and 

 (c) age and growth studies of important species. 



University of Maine cooperating; statewide; began April 1951, continuing; 

 $40,000; W. Harry Everhart, Leader; reports available. 



Address inquiries to: Lyndon H. Bond, Fish and Game Department, State 

 House, Augusta, Maine.
