IOWA (Cont. ) 



Statewide; began July 1948, to close November 1955; $2,000; R. E. Cleary 

 and Harry M. Harrison, Leaders. 



Address inquiries to: E. B. Speaker, as in No. 4 above. 



15. Continuing Inventory of the Fishes of Iowa. 



The project involves population trend determinations by netting surveys at 

 fixed stations. Each survey station is visited annually at the same time each 

 successive year to approximate similar ecological conditions. Specimens are 

 taken with trap and hoopnets and the data is handled on a catch and weigh per 

 net-hour basis. Reproduction indices are gathered at the station by use of a 

 25-foot drag seine. The geographical distribution of the various species in the 

 State is recorded. 



Statewide; began June 1949, continuing; R. E. Cleary and Harry Harrison, 

 Leaders; reports available. 



Address inquiries to: E. B. Speaker, as in No. 4 above. 



16. Angling Instructions. 



The objective is to teach productive methods of catching panfish as an aid 

 in Species control to innprove game fishing. This is to be accomplished through 

 conducting two angling schools. Kid Fish Day events, departmental instruction 

 as part of the duty of fishery employees as public contacts are made, and through 

 press and radio information releases. 



Statewide; continuing; $6,000; Charlie King and Garfield Harker, Leaders; 

 reports available. 



Address inquiries to: K. M. Madden, Division of Fish and Game, East 

 Seventh and Court Avenue, Des Moines, Iowa. 



17. New Artificial Lake Construction and Stocking. 



The objective is to provide water recreation including angling in areas now 

 lacking such facilities. This includes the stocking and opening to fishing of four 

 new artificial lakes (total acres 634); stocking two new artificial lakes (total 

 acres 1, 030); stocking and opening of one new city water reservoir (total acres 

 130); and continuous routine fish management on above areas and all other arti- 

 ficial lakes and city reservoirs. 



City of Montezuma cooperating; statewide; continuing; Charle King and 

 William Tate, Leaders. 



Address inquiries to: K. M. Madden, as in No. 16 above. 



18. Nursery Lakes. 



The project objective is to produce from artificial hatching advanced finger - 

 ling sized walleye and northern pike for statewide predator stocking as an aid 

 in species control. Shallow Freezeout Lakes and marshes are used for the 

 rearing of these fingerlings. 



Statewide: began March 1953, to close December 1953; $16,000; Garfield 

 Harker, Leader. 



Address inquiries to: K. M. Madden, as in No. 16 above. 



19. Statewide Undesirable Fish Control. 



The objective is to reduce undesirable populations in state-owned inland 

 waters to increase game fish growth rates or catchable fish. Thirty permanent 

 traps plus seining by two permanent crews using l/2-inch up to 2 l/2-ich mesh 

 bar measure net are employed. Except for concentrations in streams at barriers 

 all of the control work is confined to natural lakes.
