17. An Investigation of the Spawning Success of Innportant Ganne and Non-game Fishes 

 in the Large Impounded Waters in Missouri (Project 225). 



The two objectives of this project are: (I) to obtain a measure of the yearly spawn- 

 ing success of important fishes; and (2) to acquire a knowledge of the species 

 composition and relative abundance of the forage fishes in the large impoundments. 

 Specified areas are seined and all fish caught are counted and a sample is pre- 

 served for laboratory exannination. 



Statewide; began July 1950, indefinite; $4,100.

18. Censusing Fsh Populations in Snnall Sample Areas of the Large Impounded Waters 

 With Emulsifiable Rotenone (Project 230). 



The objective of this project is to obtain quantitative population data for certain 



species and sizes of fish, which is used in conjunction with other studies to eval- 

 uate the status of the fish populations in the reservoirs. 



Statewide; began August 1950, indefinite; $4,100.

19. A Study to Determine the Suitability of Pumpkinseed and Redear Sunfish as Forage 

 Species in Combination with Largemouth Bass (Project 311). 



This project was set up to test a combination of largemouth bass with punnpkinseed 

 and redear sunfish. A series of 10 ponds are being used for this project. They 

 are seined in mid-summer to check on the success of reproduction, and the 

 populations are sampled in the fall for age and rate of growth determinations.

20. A Study to Determine the Effect of Reversing the Order of Stocking of Ba.ss and Blue- 

 gills on the Growth Rates and Composition of Their Populations (Proj. 312). 



This project is designed to con-ipare the effects of two methods of stocking finger- 

 ling fish: (1) bass stocked in early sumnner and bluegills in the fall of the S£:me 

 year, (2) bluegills stocked in the fall and b^ss introduced the following summer. 

 In mid-summer, the ponds used are seined to evaluate the reproductive success 

 of both species. In the fall, data are collected for the analyses of the rates of 

 growth of the populations. 



St. Charles County; began July 1950, to close December 1953; $2,100.
