OHIO (Com. ) 



Statewide; closed December 1956; Clarence F. Clark, Mark O. White,

 Leaders; reports available. 



Address inquiries to: E. L. Wickliff, 1500 Dublin Road, Columbus 12, Ohio. 



2. Aquatic Vegetation Control 



Aquatic vegetation is controlled by chemical treatment and mechanical 

 cutters. Experimental use of various types of chemicals and an evaluation 

 of them is under way. 



Statewide; continuing; Clarence F. Clark, John D. Walker, Ray H. Reith- 

 miller, Mark O. White and Daniel C. Armbruster, Leaders; reports available. 



Address inquiries to: E. L. Wickliff, as in No. 1 above. 



3. Statewide Inventories 



All major public fishing waters were inventoried to check on production and 

 standing populations. The results are closely correlated with creel census to 

 determine the harvest. 



Statewide; continuing; Robert Cummins, Clarence F. Clark, Daniel C. 

 Armbruster, Mark O. White, Ray H. Riethmiller, and John D. Walker, 

 Leaders; reports available. 



Address inquiries to: E. L. Wickliff, as in No. 1 above. 



4. Planned Population Balance and Control Program 



One part of the planned population balance and control program consists of 

 corrective stocking. Several large areas were stocked with large predator 

 species, nannely, walleye pike, northern pike, and muskellunge, in an attempt 

 to improve the quality of certain pan fishes. Largemouth bass and white bass 

 were stocked in certain problem lakes with the same idea in mind.

5. New Methods of Catching Fish 



New methods of catching fish are constantly being tried. Wire traps of 

 various sizes and designs were fished experimentally in two different rivers. 

 The results will be summarized. Trot lines and float lines were fished experi- 

 mentally in Mosquito Creek Reservoir and Berlin Reservoir, and further study 

 is needed before any real evaluation can be made. Trawls have been used in 

 several inland lakes and rivers to find out how effective such a tool might be in 

 our fish management work, especially as to sampling year classes and possible 

 removal.

6. Farm Ponds 



Farm pond experimental stocking of bluegills and largemouth bass has been 

 carried on for the past three years in 12 one-acre ponds located at the United 

 States Fish Cultural Station near Buckeye Lake. The 3-year study will give 

 the results of basic stocking ratios as they apply generally to Ohio's ponds and 

 other small impo\indments . 



U. S. Fish and Wildlife Service and Denison University cooperating; U. S. 

 Fish Cultural Station, Hebron; began 1953, continuing; Ray H. Riethnniller , 

 Leader; reports available.
