27. Brook Trout Spawning Studies. 



The project is set up to secure exact information on length on spawning season, 

 number of redds in which eggs are deposited, preferred sites for redds, and 

 number of young resulting from spawning of known numbers of adults of known 

 sizes. This information is secured fron:i experinnental stream, and from screened 

 natur£:l raceways. 



Experimental sections of Hunt Creek, Montmorency County; began October 1943, 



indefinite; $1,102; D. S. Shetter, Proj. Ldr.

28. Population Studies, Hunt Creek. 



The objective is to determine residual populations of brook trout through the use 

 of various estimation techniques in waters of Hunt Creek drainage at the close 

 of angling season.

 and sex ratio of each species for comparisons between waters, and comparison 

 of growth in individual waters with statewide averages. 



Statewide; began in 1932, continuing; $6,989; J. E. Williams, Proj. Ldr.; for reports
