1. Selective Breeding Program for Trout. 



Preliminary studies on brook trout to develop, by individual selection, an improved 

 strain for artificial propagation and for angling. Selected trout have been indi- 

 vidually marked and their ability to transmit desirable characters through heredity 

 will be tested. Reciprocal crosses have been made between brook, brown and rain- 

 bow trout to test for hatchability and hybrid vigor. Egg and sperm viability after 

 storage in several media over varying periods of time was tested. Studies are 

 being conducted on methods of transporting milt and unfertilized eggs.

2. Biological Survey of Streams. 



Biological and physical surveys are conducted on streams to formulate proper 

 stocking policies. 



Statewide; began in 1932, continuing; $10,000; Individual stream surveys available.

3. General Lake Survey. 



The project aims to determine factors limiting the satisfactory production and har- 

 vest of lake fish populations, and to provide practical recommendations for the 

 improvement of adverse conditions affecting such harvest. Analysis is accomplished 

 through the ordinary techniques applied to such surveys and includes the evalua- 

 tion of lake quality, age and growth of fishes, and the ecological relationships of 

 fish populations. Findings to date indicate that when poor lake fishing is found the 

 underlying cause is usually unbalanced fish populations. Although liberalization of 

 the regulations on pan-forage species may be desirable, perhaps greater size re- 

 strictions on pikeperch, northern pike, pickerel, muskellunge, and bass are 

 necessary for the purpose of increased predatory function and improved repro- 

 duction.
