10. Guiding of Young Salmon and Trout by Non-Electrical Means. 



The objectives of the project are to determine the effects of various water 

 velocities and current patterns; air bubbles and water jets; objects in water 

 such as stakes, reflecting surfaces, and floats; and light, but not sound, on the 

 behavior of young salmon and trout for possible use in guiding. Also, the 

 project will attempt to determine the extent to which the above stimuli may be 

 used in conjunction with eletricity. 



U. S. Army Corps of Engineers cooperating; hdqrs. University of Wash- 

 ington; began July 1, 1953, to close June 30, 1955; $45,000; Leon A. Verhoeven, 

 Leader. 



Address inquiries to: R. Van Clave, Director, School of Fisheries, Uni- 

 versity of Washington, Seattle 5, Wash. 



11. Effects of Electricity on Salmon and Trout. 



The project objectives are to determine the following in relation to the use 

 of electricity in guiding young salmon and trout: Immediate or delayed mortality; 

 cause and extent of non-fatal injuries; physiological factors causing orientation 

 toward the anode in a D. C. field; response to A. C. of different frequencies in 

 the high frequency range; changes in conductivity of young anadromous salmonoid 

 fishes during fresh-water and downstream migrant stages; modification of be- 

 havior; the most efficient arrangements of field, electrodes, etc. 



U. S. Army Corps of Engineers cooperating; hdqrs. University of Washington; 

 began July 1, 1953, to close June 30, 1955; $39,000; Leon A. Verhoeven, Leader. 



Address inquiries to: R. Van Cleve, Director, as in No. 10 above." 



Pollution Control Commission 



1. An Investigation of Pollution in Grays Harbor. 



This project was undertaken to determine the effect upon fish and fish food 

 organisms of all wastes which are discharged into Upper Grays Harbor. The 

 large sulphite pulp mill at Hoquiam has been impounding waste sulphite liquor 

 during periods of low flow in a 70-acre lagoon on Rennie Island. Other wastes 

 from the Cities of Aberdeen and Hoquiam are discharged without treatment 

 into the waters of Grays Harbor. The field collections included tow net hauls, 

 bottom fauna, and fish for a population study. 



U. S. Public Health Service and State Department of Fisheries cooperating; 

 Aberdeen-Hoquiam area; began June 10, 1953, to close September 3, 1953; 

 Donald R. Peterson, Leader; reports available. 



Address inquiries to: Washington Pollution Control Commission, 408 Old

 Game-fish and Hatcheries, Fish and Wildlife Service, Swan Island, Portland 18, 

 Ore. 



2. A Method for the Introduction of Malachite Green Into Hatchery Water Supplies. 



The objective is to develop a fast, easy method of treating an entire hatchery
