2. Fish Guiding 



The objective is to determine non-electrical means of guiding young down- 

 stream, migrant salmon and steelhead trout, at dams and other water usage 

 projects, into areas of safe passage. The present studies have been concerned 

 primarily with the use of light to divert salmonoids into desired areas.

3. Water Quality Studies 



The objectives are to collect, analyze, and document information concern- 

 ing past and existing water qualities of sections of the Columbia River system 

 near sites of proposed dams. The data will be evaluated to ascertain the 

 changes in water quality which are taking place now and the changes which may 

 take place as the result of the proposed dams.

4. North Pacific Salmon Studies 



Development of serological and other methods for the identification of 

 specific strains of the bacteriunn Chondrococcus columnaris from salmon and 

 determination of the geographical distribution and relationship of the strains 

 to host fishes. The initial phase of the study has dealt primarily with fishes 

 from the Columbia River. The ultimate objective is the determination of the 

 feasibility of using microorganisms to identify races of salnnon. Information 

 regarding the consequence of the organisms as a cause of mortalities in 

 salmon is also being sought. 



Marine Vibrios, metacercariae of the fluke (Troglotrenna salnnincola) 

 and the etiological agents of kidney disease and tuberculosis are sonne of the 

 organisms singled out for specific study.

5. Salmon Fatigue Studies 



The objective is to study the swimming abilities of adult upstream migrant 

 salmon and steelhead to learn the capacities of these fish to perform physically. 

 Specific study is being made of: (1) the length of time various swimming speeds 

 can be maintained; (2) the maxinnum swimming speed which can be attained; 

 (3) the effects of fatigue induced by prolonged swimming activity on tinne re- 

 quired for recovery after complete exhaustion and life span; and (4) the effects 

 of environmental conditions on swimming performances.

The Relation of Preference of Pacific Salnnon to Experimentally Induced 

 Physiological Reactions 



The objective of this project is to determine the relationship of endocrine 

 activity to reactions of salmon fingerlings to temperature, salinity, carbon- 

 dioxide tension, and water flow.
