DISTRIBUTION OF SPAWNERS 



Sashin Creek has 13,629 rn. of spawning 

 ground between the weir and an innpassable 

 falls. The distance between the weir and the 

 falls is 1,200 m., but the upper 300 m, are 

 mostly in a narrow canyon and are rarely used 

 by indigenous pink salmon for spawning. 



The transplanted fish began to move upstreann 

 from the weir within 24 hours after they were 

 released above the weir. Five pink salmon 

 were in the pool 366 m. above the weir on 

 August 26, 1 day after the first fish were re- 

 leased into the stream (table 2). 



We divided the spawning ground into four 

 sections and counted the number of female 

 pink salmon in each sectiondaily. SectionI was 

 farthest upstream and section IV farthest down- 

 stream. Together the sections included 96 

 percent of the total spawning ground: section 

 I--22 percent, section II--30 percent, sec- 

 tion III- -27 percent, and section IV-- 17 percent. 



The spawning ground Is that portion of a stream usable 

 for spawning and does not include pools. 



A total of 2,193 pink salmon spawners en- 

 tered Sashin Creek in 1964, of which 1,305 

 were females. The first female occupied the 

 spawning ground August 28, and the die-off of 

 spawned female pink salmon was complete by 

 October 3. Spawning reached its peak on Sep- 

 tember 16, when 695 females were counted on 

 the spawning ground. 



We assumed that 1,253 females, or 96 per- 

 cent of the 1,305 females in the stream, spawned 

 in the four study sections. The percentage 

 spawning in eacli section was obtained by sum- 

 ming the daily counts in each section and divid- 

 ing this number by the summed daily counts in 

 all sections. 



The density of female pink salmon was 

 highest in downstream section IV and low- 

 est in upstream section I (table 3). This dis- 

 tribution is characteristic of small runs of 

 pink salmon in Sashin Creek (Merrell, 1962). 

 Although fresh-water survival of pink salmon 

 is better in section I (McNeil, 1966; 1968), 

 this area is only lightly used except in years 

 of large runs.
