and to evaluate the effects of various physical phenomena upon reproductive 

 success and survival of the fishes in two Ozark streams.

27. Practicality and Econonnic Feasibility of Rearing and Stocking Largemouth Bass 

 of One Pound Size. (FA: F-l-R in part) 



The objective of this study is to determine the practicality and economic 

 feasibility in terms of return to the creel of rearing and stocking bass of one 

 pound size. Various types of ponds have been stocked at various rates with 

 bass fingerlings. Those which reach one pound size will be stocked in Lake 

 of the Ozarks. Economic feasibility will be determined by the prorated cost 

 of the stocked bass which may be caught within a reasonable length of time. 



Statewide; began March 1952, to close 1954; Richard Marzolf, Leader. 



Address inquiries to: Richard Marzolf, Fish and Game Division, Conser- 

 vation Commission, 903a Elm Street, Columbia, Mo. 



28. Investigation of the Natural Reproduction of Channel Catfish with Special Refer- 

 ence to Small Impoundments. (FA: F-l-R in part) 



Objectives of this study are to determine the conditions necessary for ef- 

 fective natural reproduction of channel catfish and to devise methods for creating 

 these conditions in small impoundments. Factors influencing the survival of fry 

 are being investigated. Initial abundance of fry, turbidity of water, suitable 

 escape cover, and presence of predators or competitors are among the factors 

 receiving attention.

29. A Survey of Gigging on Representative Streams of the Missouri Ozarks. (FA: 

 F- 1 -R in part) 



Objectives are to determine the portion of the various streams subject to 

 gigging, to- ascertain the techniques and equipment used, the effect of various 

 physical factors upon gigging activity, and to determine the rate of success and 

 species composition of the catch of giggers. Four watersheds are to be used 

 for the study. Information is to be obtained by direct observation and from inter- 

 views with Conservation Agents, giggers, and other reliable local residents. 



Big Piney, Niangua, Current, and James River Watersheds; began March 

 1954, to close 1955; Richard Marzolf, Leader. 



Address inquiries to: Richard Marzolf, as in No. 27 above.

1. Effect of Carp on the Limnology of Farm Ponds. 



A two-year intensive study of the effect of a large population of carp on the 

 limnology and fish populations of Missouri farm ponds. Turbidity, water chem- 

 istry, temperature and biological effects are receiving especial attention. 



Statewide; began 1953, to close 1955; Joseph L. Hendricks, Leader. 



Address inquiries to: Dr. Robert S. Campbell, Wildlife Research Unit, 

 Wildlife Conservation Building, University of Missouri, Columbia, Mo. 



2. The Effect of Strip-mine Lake Pollution on the Chemistry and Biota of a Stream. 



The study has two major phases: (1) The effect of strip-mine spill (acid 

 pollution) on the chemistry and biota of a stream; and (2) the dynamics of acid
