21. Control and Eradication of Aquatic Vegetation with Several Weed Control Agents 

 (Project 325). 



This project is designed to test various herbicides on a number of plants with the 

 object of determining their effectiveness over a period of time, concentrations 

 necessary for control, and their effectiveness when used with various carriers. 



St. Charles and Boone Counties; began June 1950, indefinite; $2,100.

22. The Use of Inorganic Fertilizers for Fish Production in Small Lakes and Ponds 

 (Project 330). 



The objective of this project is to measure the availability of several plant nutrients 

 when added to water, and to deter n>ine the most economical and efficient method 

 of fertilization in Missouri farm ponds. The experimental ponds have been stocked 

 with bass and bluegill. 



St. Charles and Boone Counties; began May 1951, to close Decennber 1953; $5, 000.

23. Fisheries Management Planning and Research Project (FA: F-l-R). 

 This project includes four principal activities: 



(a) Creel census and estimates of total fishing pressure. 



A statewide, continuing, general creel census is being carried on to determine 

 the utilization of the fishery resources within the State, detect trends, and 

 determine the effect of regulations. Fishing pressure determination is made 

 from information gathered from the creel census and from an analysis of fish- 

 ing licenses sold and questionnaires submitted. 



Statewide; began May 1946, continuing.

(b) A study of fish populations in selected streams. 



The population densities of the various species are determined and evaluated 

 in relation to each other in three test sections in each of 10 watersheds. Samples 

 are collected at each station three times annually. Fish tagged and released 

 in this study are used also to determine migration patterns for the species. 

 Special data is being collected with regard to abundance, distribution and 

 ecology of forage fishes caught in these study streams. On the White River 

 and Salt River, emphasis is being placed on a study of the growth rate of 

 important stream fishes. 



Statewide; began 1946, continuing; John L. Funk, Perry E. Robinson, Edward M. 



Lowry, Charles A. Purkett, Jr., Leaders.
