efficient method of fertilization in Missouri farm ponds. The experimental ponds 

 are stocked with bass and bluegill.

18. A Statewide, Continuing General Creel Census. (FA: F-l-R in part) 



The census is carried on to determine the utilization of the fishery resources 

 of the State, detect trends and to determine the effect of regulations. Conserva- 

 tion agents record creel data fron-i 20 percent of all anglers interviewed in the 

 regular course of their duties as enforcement officers. These data are tabulated 

 by fishery technicians. Rate of success and species composition of the catch is 

 determined for the various watersheds and impoundments and for the major zoo- 

 geographic areas of the State. Results for previous years are available for 

 comparison. 



Statewide; began May 1946, continuing; John L. Funk, Leader.

 Commission, 903a Elm Street, Columbia, Mo. 



19. The Estimation of Total Fishing Pressure on Missouri Waters. (FA: F-l-R in 

 part) 



This study has the objective of developing a sound nnethod for estirrtating the 

 number of fishing trips made and the number of fish caught annually in waters of 

 the State. Estimations to be made using information on number of fishing trips, 

 county of residence of fishermen and number of fish caught from the creel census, 

 number of licenses sold in each county, and the average number of fishing trips 

 made by licensees, the latter piece of information obtained by a questionnaire. 



Statewide; began 1952, to close 1954; John L. Funk, Leader. 



Address inquiries to: John L. Funk, as in No. 18 above. 



20. A Study of the Composition and Relative Abundance of the Fish Population in 

 Selected Areas of Study Streams. (FA: F-l-R in part) 



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

 of the fish population in three test sections on each of eight watersheds. The 

 cause of any trends observed is to be determined, if possible. Previously, 

 three collections were made annually but starting in 1954 only one collection 

 will be made at each study section. 



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

 Charles E. Purkett, Jr., Leaders. 



Address inquiries to: John L. Funk, as in No. 18 above. 



21. A Study of the Migration of Stream Fishes. (FA: F-l-R in part) 



This study is made to determine the extent of migration of warm-water stream 

 fishes and to correlate, if possible, migration with season, water conditions, 

 and population pressure. Fish collected in the population study are tagged and 

 released. Records of tagged fish reported caught by fishermen are analyzed to 

 determine for each species average time and distance travelled, and direction 

 and season of greatest migratory activity. 



Statewide; began 1947, continuing; John L. Funk, Leader. 



Address inquiries to: John L. Funk, as in No. 18 above. 



22. A Study of the Growth Rate of the Important Stream Fishes in Various Missouri 

 Watersheds. (FA: F-l-R in part) 



Objectives of this study are to determine the age and rate of growth of
