Table 6. --Length, weight, and fecundity of 60 female king salmon 

 in four age groups, Cook Inlet, 1959 



in the Yentna and Skwentna systems in the 

 upper Susitna River by July 7. In Resur- 

 rection, Sixmile, and Bird Creeks of 

 Turnagain Arm, king salmon appeared about 

 the second and third weeks in June, the same 

 time as they appeared in streams on theKenai 

 Peninsula. The Beluga River system had king 

 salmon in the clear tributaries in late June 

 and in July, but the fish could not be seen in 

 the river itself because of the turbid water. No 

 king salmon were seen in the Matanuska 

 drainage on a survey flight that was made in 



July, but residents report use of this system 

 by king salmon. 



Relative Magnitude 



We were unable to determine if spawning 

 occurred in any of the turbid glacial streams 

 surveyed. Because of this, the vast area in- 

 volved, and the large number of small tribu- 

 tary streams, we could not estimate the rela- 

 tive magnitude of the escapement in the Cook 

 Inlet area or even between systems.
