23. An Intensive Creel Census of an Ozark Stream Stocked Annually With Fingerling 

 Smallmouth Bass 



The objectives of this study are to estimate the annual yield of fish to anglers, 

 to determine the effect of annual stocking of fingerling smallmouth bass upon fish- 

 ing success, and to evaluate the cost of such stocking. An intensive creel census 

 has been in operation since 1951. information is collected in a systematic manner 

 so that the results can be expanded to provide estinnates of the yield for the entire 

 season and the entire length of the stream. Fingerlings were stocked annually 

 fronn 1951 to 1955. These fish were permanently marked by fin-searing so their 

 contribution to the creel can be recognized.

24. An Intensive Creel Census of a Missouri Ozark Stream With a Year-round Open 

 Fishing Season 



Objectives of this study are to estimate the yield of fish to anglers and to 

 determine the effect of the year-roiind open season upon the yield, especially 

 of smallmouth bass. An intensive creel census has been in operation on the 

 stream since 1951. The year-round open season will go into effect in 1957. By 

 comparing before and after data, an evaluation of the effect of the year-round 

 open season will be possible.

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

 in a Missouri Ozark Streann with a Year-round Open Season 



This study is designed, (1) to add to information on the spawning 

 success and survival of young of the important game, non-game, and forage 

 fishes (especially smallmouth bass); (2) to determine the species composi- 

 tion and relative abundance of forage fishes; (3) to determine the effect of a year- 

 round open season upon the reproductive success of the important game and 

 non-game fishes in an Ozark stream; (4) to develop and standardize a method 

 for the determination of the reproductive success of game, non-game and forage 

 fishes in Ozark streams. 



Diangua River; began December 1956, continuing; Perry E. Robinson, 

 Charles A. Purkett, Jr. , George G. Fleener, Leaders. 



Address inquiries to: Perry E. Robinson, as in No. 20 above. 



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

 in a Missouri Ozark Stream With a Year-round Open Season 



This study is designed to determine the species composition and relative 

 abundance of fishes present in an experimental stream selected as representative 

 of smallmouth bass streams of the Missouri Ozarks, and to determine the effect 

 of a year-round open season upon the existing population of smallmouth bass 

 and other important species. A population inventory has been in operation 

 since 1951. By comparing before and after data, an evaluation of the effect of 

 the year-round open season may be possible.
