 surface tow net. At that time the young chinook are large 

 enough to dive and they become unavailable to our sampling 

 gear. 



A considerably more modest experiment was 

 conducted this year on the Nooksack River and Bellingham 

 Bay area where 102,000 chinook and 169,000 coho were 

 marked and released at the Kendall Creek Hatchery and tow 

 netting was conducted in Bellingham Bay for parts of 17 

 days. These 17 days were from May 15 through June 20, in 

 that interim. We ceased on June 20 because we just ran out 

 of money, charter money. 



During that time, marked fish were captured 

 during the entire period. 1,500 fish were captured, of 

 which 140 were marked. All but 420 of the 1,500 were 

 chinook. This is by the board, but incidentally, accordirg 

 to our calculations, all of the chinook in Bellingham Bay 

 are of hatchery origin. We marked 10 percent of the fish 

 released at the hatchery and 10 percent of the fish we 

 caught were marked. The confluence limits on our estimates 

 haven't been determined as yet. 



Coho, the silvers, do not seem to be as 

 available as chinook in tow netting, although we captured 



coho or silver in all areas of Everett Bay, Elliott Bay, 



and Bellingham Bay. The total sampling hours in Bellingham
