failures and reasons they failed, and by following the results of various stocking 

 procedures, angling success and harvest fronn experimental ponds. Experimental 

 farm ponds are being chosen over the entire State, cleaned of existing fish, and 

 stocked according to experimental plans.

4. Land Use Practices in Relation to Trout Streams. (FA: F-4-R in part) 



The effects of various land use practices on trout streams, with particular 

 emphasis on bottom fauna, water temperature, stream flow, turbidity, trout 

 populations, food habits, and stream fertility are under investigation. The 

 project is using several study areas developed by the U. S. Forest Service Ex- 

 periment Station on the Coweeta Area. These areas have different land use 

 practices being carried out on them, such as timber cutting, farming, grazing, 

 etc. Sampling stations have been set up on each of these streams which measure 

 water tennperature and flow, and from which bottom samples are collected 

 regularly.

 Indian Wildlife Management Area; began July 1, 1952, to close July 1, 1956; 

 $6,000; L. B. Tebo, Jr., Leader; reports available.

5. Fish Management Investigation on Trout Streams. (FA: F-4-R in part) 



This section of the project is designed to obtain data on public trout streams 

 and their carrying capacities, present populations, annual yields, angling 

 pressures, and catch per unit effort. Streams on closely supervised manage- 

 ment areas are stocked, in part, with marked trout at predetermined times 

 during the trout fishing season. Each trout caught from these management 

 area streams is brought through the respective checking station. In this way 

 numbers, species, weights, and marked fish are carefully recorded. Each 

 fisherman records time fished and stream fished as well as numbers and species 

 caught.

1. Relationship of Oxygen Consumption of Tissues of Marine Fishes to Their 

 Activity and Habitat. 



Fishes occupy many different habitats and exhibit varying degrees of activity. 

 A basic question arises as to how these organisms are physiologically and mor- 

 phologically adapted to fit their way of life. The present physiological investiga- 

 tion concerns relationship of the oxygen consumption of fish tissues to their 

 activity and habitat. 



Duke Marine Laboratory, Beaufort; began June 1952; $300; F. John Vernberg, 

 Leader; reports available. 



Address inquiries to: Dr. F. John Vernberg, Department of Zoology, Duke 

 University, Durham, N. C. 



2. Correlation Between Gill Area, Habitat, and Activity in Marine Fishes. 



Marine fish species are being studied to determine the correlation between 

 gill area, habitat, and activity of the fishes.
