^ 1957 experiments overlapped on these dates. 



In 1958 about twice as many fish were 

 tagged in experiment 1 as in any of the other 

 three. Figure 6 shows that the composite 

 reflects this, i.e., nearly twice as many 

 recoveries were derived from experiment 1 

 as from any of the others. In 1958 Kijik Lake 

 was again in contrast with the composite, 

 though the pattern of high and low numbers of 

 recoveries per experiment was preserved. No 

 other recovery points appeared to contrast 

 significantly. 



In 1959 (fig. 7) most of the tags were put on 

 in experiments 2 and 3, and once again the 

 return was significantly higher from these 

 than from experiments 1 and 4. For the third 

 time the Kijik Lake distribution was in contrast 

 with the composite and for the third year 

 failed to have representation in all four ex- 



periments. Lower Talarik Creek (No. 23) was 

 represented by eight recoveries, all lumped 

 in experiments 2 and 3. The distributional 

 pattern of the composite was clearly pre- 

 served, however, so the recovery point does 

 not appear significantly discrepant. 



In summary of the 3 years' data, it appears 

 that only Gibraltar River, Newhalen-Nondalton, 

 and Kijik are notably in contrast with the 

 composites. Kijik is obviously the most con- 

 sistently aberrant recovery point, tending to 

 have fewer late- run fish. The other two con- 

 trasted most in 1957, though Gibraltar received 

 a slightly higher number of late-run fish, and 

 Newhalen-Nondalton a slightly higher number 

 of early-run fish in all 3 years. All three of 

 these recovery points will be considered 

 further in the statistical analysis.
