2 to spawn, and after hatching the juveniles of these fish 



3 spend varying periods of time in the tributary streams 



4 and the near -shore areas of Puget Sound before moving 



5 seaward . 



6 The juvenile salnoon studies were conducted 



7 in three of the study areas, in Bellingham, in Everett 



8 and Port Angeles. They consisted of, first, occurrence 



9 studies to determine the migration routes and distribution 



10 of wild juvenile salmon in each study area. Secondly, 



11 field bioassay tests to determine the survival of these 



12 fish in waters polluted by pulp and paper mill wastes and 



13 insofar as possible to determine what specific water 



14 quality parameters it is that does kill the fish that do 

 die. 



16 The occurrence studies made by the Project, 



17 along with similar studies made for the pulp mills by 



18 the Fisheries Research Institute at the University of 



19 Washington^ showed that wild juvenile salmon are present 



20 in large numbers at certain times of the year in each of 



21 the three areas studied, and more importantly that the 



22 migration patterns for a significant portion of these 



23 fish are through the zones of acute pollution near the 



24 mill outfalls.
