Environmiental Studies. 



Objectives of the project are to determine and evaluate factors of the environ- 

 nnent, both natural and man-nnade, controlling the survival and abundance of 

 salmon. Natural salmon food studies in both fresh and salt water are in progress. 

 The effects of pollution on both the salmon and its food in estuaries is being ap- 

 praised. Effects of stream conditions on natural and hatchery salmon production 

 is under study. 



Puget Sound streams, Minter Creek stream, and Deception Pass Marine 

 Research Station; began 1937; indefinite; $80, 000; William A. Smoker, H. T. Heg, 

 E. Salo, and Gil Holland, Leaders; reports available. 



Address inquiries to: Don Johnson, as in No. 1 above. 



Downstream Migration Mortalities at Power Dams. 



The objective of the project is the determination of mortalities to young 

 salmon that occur when they pass through power turbines or over high dam spill- 

 ways on their downstream migrations to the sea. 



Various hydroelectric dams in Washington; began 1952, indefinite; $50, 000; 

 Dale Schoeneman, Leader.

Salmon Sport Fishery Investigation. 



Routine visits and checks are made at the 160 boathouses in Puget Soxind 

 and the Straits of Juan de Fuca. Fishing intensity and gear study data is com- 

 piled. Annual sport catch of salmon by species, by area, and by month is 

 estinrvated from checks and boathouse reports. Other phases of the project 

 include: Mark recoveries, catch sampling, and salmon derby checks. 



Hdqrs. State Fisheries Laboratory; began 1938, continuing; $14,000; 

 J. W. Fitzgerald, Leader; reports available.

An Investigation of the Effects of Pollution on Fish and Fish Food Organisms. 



This project was undertaken in an attempt to determine the effects of botla 

 industrial and domestic wastes on downstream migrant salmon and fish food 

 organisms. Waste from four pulp mills and untreated sewage from the City of 

 Everett discharge in or in the vicinity of the Snohomish River, parent stream 

 for a large stock of anadromous fish. Studies will include determinations for 

 D. O. , sulfite waste liquor, salinity, temperature, HtS, etc. The field col- 

 lections will include net hauls, bottom fauna, and fish, for population density 

 and variety studies. 



Washington Pollution Control Commission cooperating; Everett Harbor, 

 Snohomis River, and Stillaguamish River; began January 18, 1954; to close 

 October 1954; Donald Johnson, Leader; reports available.
