18. A Study of the Important Stream Fishes in Various Missouri Watersheds 



This study is being done to determine the age and rate of growth of all the 

 important stream fishes in representative watersheds, and to detect growth 

 trends and effects of environnnent. The results of this study are correlated with 

 tliose of other investigations to develop a comprehensive management plan for 

 the watershed. Information from individual watershed studies is being combined 

 to set up a standard for statewide comparisons of fish growth. The scale samples 

 used are collected in the population study. 



Statewide; began 1947, continuing; Charles A. Purkett, Jr. , Leader; reports 

 available. 



Address inquiries to: Charles A. Purkett, Jr. , Fisheries Section, Con- 

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



19. A Study of the Connposition and Relative Abxindance of the Fish Population in 

 Selected Areas of Study Streams 



This study is carried on to determine the composition and relative abundance 

 of the fish population in three sample areas on each of nine watersheds. Cause 

 of any trends observed is to be determined, if possible. One collection has been 

 made annually since 1954 at each test section. 



Statewide; began 1956, continuing; John L. Funk, Ronald E. Gumtow and 

 Robert W. McVey, Leaders. 



Address inquiries to: John L. Funk, as in No. 17 above. 



20. The Abundance, Distribution, and Ecology of Forage Fishes in Streams 



The objectives of this study are: (1) To determine the species composition of 

 small fish collections made in connection with the population study, (2) to evalu- 

 ate yearly fluctuations in species composition and relative abundance and, (3) to 

 establish distribution records. 



Statewide; began 1947, continuing; Perry E. Robinson, Leader. 



Address inquiries to: Perry E. Robinson, Fisheries Section, Conservation 

 Commission, 903a Elm Street, Columbia, Missour.

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

 in a Missouri Ozark Stream Stocked With Fingerling Smallniouth Bass 



The objectives of this study are to obtain information on, (1) the spawning 

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

 fishes; (2) to determine the species composition and relative abundance of forage 

 fishes; (3) to determine the effect of stocking of smallmouth bass fingerlings upon 

 the reproductive success of the important game and non-game fishes and; (4) to 

 develop and standardize a method for the determination of the reproductive success 

 of game, non-game, and forage fishes in Ozark streams. 



Big Piney River; began December 1956, continuing; Perry E. Robinson, 

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



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



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

 in a Missouri Ozark Stream Stocked with Fingerling Smallmouth Bass 



This study was designed to determine the species composition and relative 

 abundance of fishes present in a stream which was stocked annually with finger- 

 ling smallmouth bass. Stocking was done to determine the effect of stocking 

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

 fish. A census crew makes collections from three test sections on the stream 

 two times annually. 



Big Piney River; began 1951, to close 1958; George G. Fleener, Ronald B. 

 Gumtow, and John L. Funk, Leaders.
