mixture of races that make up the June run in the 

 Peninsula area. 



3. Isolation of migratory runs -Time of 

 occurrence of migratory runs in the fishery is best 

 shown by comparing local and nonlocal tag recov- 

 eries in relation to time tagged (figure 4). Most 

 pink salmon bound for distant places have passed 

 through the area by July 10; few traveling fish 

 are found after July 1. Additional analysis is 

 needed to determine if all pink salmon in the area 

 during June are migrants, or if the runs consist 

 of a mixture of local and nonlocal stocks. Pres- 

 ent evidence indicates that most of the early-run 

 fish should be considered migrants. From tag 



returns, it is apparent that local fish far out- 

 number migrants after July 1. For practical 

 purposes this date should be used to separate and 

 distinguish the two groups. 



Patterns of movement within the area 



After July 1, when the catch can be con- 

 sideredto be composed mainly of Peninsula fish, 

 the patterns of local movement are of primary 

 interest. Results of tagging after July 1 indicate 

 that these runs can be differentiated both in space 

 and in time. 



For the purposes of discussion and com- 

 parison, the results of tagging experiments per- 

 formed over short intervals of time at the same
