 of the higher sulfite waste liquor concentrations. The 

 concentrations in Everett under the tests, however, were 

 not as high as those in areas in Bellingham Bay, which 

 apparently support salmon. Tyler's work also indicated 

 that the fish may migrate through Everett Bay much faster 

 than they do through either Elliott Bay or Bellingham Bay. 



The fish were constantly of one size, indi- 

 cating a new crop, either that or absolutely no growth, 

 but the only way to check this, of course, is once again 

 with marked individuals. 



In 1966 we did conduct a mark and recapture 

 experiment in the Snohomish River-Everett Bay system when 

 157,887 marked chinook from the May Creek Hatchery were 

 released in two areas of Everett Bay. Six days of sam- 

 pling showed recoveries along the waterfront in Everett 

 Bay during the first day or two only. After that time 

 we were unable to find chinook anywhere. Less than 100 

 chinook were caught in the bay and of these less than 20 

 were marked. I don't have the marked or unmarked ratios 

 of these releases at the hatchery, but I feel we have 

 enough information that we were sampling the group that 

 we had released and we followed it out through the bay. 



Ten days later an additional 50 or 60 of 

 these marks--the reason I don't know whether it is 50 or 60,
