(c) Smallmouth bass studies. 



Ozark streams are the location for these intensive studies to determine abun- 

 dance, species composition, estimates of annual yield, and effects of stocking 

 of this species. 



The Big Piney and Niangua Rivers; began August 1950, continuing.

(d) Largemouth bass stocking study and investigation of reproduction of channel 

 catfish. 



The econonnic feasibility and practicality of rearing bass in bottomland lakes 

 and stocking one pound largemouth bass is being investigated. An investiga- 

 tion is being made to determine the conditions necessary for effective natural 

 reproduction of channel catfish and methods for creating these conditions are 

 being studied. 



Statewide; began March 1952, continuing.

1. Age and Growth of the White Grapple in Missouri. 



The objectives of the project are to verify the scale method for the white crappie by 

 raising known age fish; to compare the growth rates of five white crappie popula- 

 tions from different reservoirs within the State; to compare the growth rate of a 

 new population with that of old populations, to describe the seasonal growth 

 picture of the white crappie by an intensive study at the Niangua Arm of the Lake 

 of the Ozarks . 



Statewide; Conservation Commission and Univ. of Mo. cooperating; began in 1949, 



planned for 3 years.

2. Limnological and Fishery Investigation at the Niangua Arm of the Lake of the Ozarks. 



The project includes: a long-term study of the growth rate of the white crappie, 

 description of the growth rates of rough and game fishes within this arm of the 

 lake, determination of the influence of inflowing spring water on the limnology of 

 this arm, description of the summer migration of the white bass into this inflow- 

 ing spring water. 



Niangua Arm of the Lake of the Ozarks; Conservation Commission and Univ. of Mo. 



cooperating; began in 1949, indefinite.
