express or parcel post, utilizing plastic bags and corrugated boxes is under 

 development. A number of test shipnnents have been made. The method 

 utilizes a small amount of water, several ounces of fish per container, hyp- 

 notic type drugs, and oxygen.

1. Razor Clam Management Studies 



The objective is to determine maximum annual yield from razor clam stocks. 

 The project involves extensive sampling of sport and commercial catches to de- 

 termine digger success and age composition of sport and commercial catches. 

 Methods of relating success of spawning to abundance of year-class as it 

 progresses through the fishery are under study.

2. Coastal Salmon Studies 



General survey work to locate and correct factors that limit salmon pro- 

 duction in Oregon coastal streams. Studies involve enumeration of certain 

 runs in selected areas, collection of data on gill net fisheries in streams that 

 are open to fishing, and relationships between spawning escapements and re- 

 cruitment. 



One aspect of work involves analysis of stomach contents of fingerling 

 silver salmon to determine if food is a limiting factor in natural production 

 of this species in Oregon. Ecological studies are also conducted at a small 

 weir on a tributary of a representative stream. 



Coastal streams; began 1946, continuing; $30,000; Raymond A. Willis, 

 Leader; reports available.

3. Hatchery Biology Studies 



Experimental diets are being tested to find the most economical, nutri- 

 tious diet for rearing salmon and steelhead trout in hatcheries. Major empha- 

 sis has been put on use of marine scrap fishes and fish processing plant 

 wastes. Work is currently being done to control rancidity in prepared meals. 

 One diet is now being tested at production level. 



In addition to diet studies, investigations of diseases of salmon and steel- 

 head raised in hatcheries are being conducted. Primary attention has been 

 given to kidney disease and tuberculosis. Limited work has been done on test- 

 ing the toxicity of various algacides in regard to salmon and steelhead fry 

 and fingerlings.
