important stream fishes in certain designated watersheds, to detect growth 

 trends, and to correlate the results of this study with those of other investiga- 

 tions to develop a comprehensive management plan for the watershed. Scale 

 samples collected in the population study are used. All important game and 

 rough fishes are studied. An attempt is made to correlate growth with environ- 

 mental factors.

23. The Abundance, Distribution and Ecology of Forage Fishes in Streams. (FA: 

 F-l-R in part) 



Objectives of this study are to determine the species composition of small 

 fish collections made in connection with the population study, to evaluate seasonal 

 and yearly fluctuations in species composition and relative abundance and to 

 establish distribution records. The effect of environmental conditions upon the 

 population of forage and other small fishes is given special attention.

 servation Commission, 903a Elm Street, Columbia, Mo. 



24. An Intensive Creel Census of Two Similar Smallmouth Bass Streams. (FA: 

 F-l-R in part) 



Objectives of this study are to estimate the annual yield to anglers, to de- 

 termine the effect of annually stocking smallmouth bass upon fishing success 

 and to evaluate the cost of such stocking. One stream is stocked annually with 

 fingerlings, the other serves as a control. Clerks collect creel census infor- 

 mation in a systematic manner so that the results can be expanded to provide 

 estinaates of the yield for the entire season and the entire length of each stream. 

 Stocked fish are fin-clipped so that their contribution to the creel can be 

 recognized.

25. A Study of the Species Composition and Relative Abundance of Fishes Present 

 (With Particular Reference to Smallmouth Bass) in Two Missouri Smallmouth 

 Bass Streams. (FA: F-l-R in part) 



Objectives of this project are to ascertain the species composition and 

 relative abundance of fishes present in two similar streams, one of which is 

 stocked annually with fingerling smallmouth bass, to determine the effect of 

 stocking upon the existing population and to evaluate the rate of survival of the 

 stocked fish. 



Big Piney and Niangua River watersheds; began August 1950, continuing;

Address inquiries to: George G. Fleener, as in No. 24 above. 



26. A Study of Trends in Reproductive Success of Game, Rough and Forage Fishes 

 in Two Missouri Ozark Streams. (FA: F-l-R in part) 



Objectives of this study are to obtain information on the spawning success 

 and survival of important game and rough fishes (especially smallmouth bass), 

 to determine the species composition and relative abundance of forage fishes,
