1. Fisheries Investigation of Region I 



The objective is to introduce and determine usage of threadfin shad by 

 other fish and the result upon the fisherman's catch. Fishing pressure on 

 warm water fish of Lake Mohave and on trout below Hoover and Davis Dams 

 by residents and nonresidents, the most economical size classes of trout 

 stocked, and the best time of the year for stocking in terms of return to the 

 fisherman's creel are also determined. 



The project leader and two assistants are making a comparative creel 

 census of the areas to be covered and are collecting stomach samples, scales, 

 and length data. Fin clipped and tagged trout are planted.

1. A Connparative Fisheries Study 



This is a comparison of the physical, chemical, and biological features 

 of Lakes Catherine, Hamilton, and Ouachita. These impoxindments are located 

 on the upper reaches of the Oiiachita River and are very similar except for 

 age. Fishing success seems to be directly affected by the age of the impovmd- 

 ment with the newer impoundments providing the best fishing. The purpose of 

 the project is to produce a management plan which will improve fishing in the 

 older impoundments and maintain good fishing in the newer impoundments.
