MIGRATION OF ADULT SOCKEYE SALMON. 27 
Table 15 gives the number of specimens, which were marked at 
each of the marking stations, recovered from each of these regions, 
and the average number of days en route. It is apparent from this 
that even with this increase in the size of the regions no significant 
and consistent difference in the length of time required to reach the 
different regions appears, and for the purposes of statistical analysis 
it was necessary to consider all of the returns from the main Cana- 
dian waters as constituting a single group, and to combine regions 
10 to 16 into one region, 10. It is much to be regretted that the 
data are not such as to make possible a reliable estimate of the rate 
of travel in the river itself. Whether this is due to the manner of 
collecting and recording the data can not be stated. Although 
these records from Canadian waters do not admit of detailed analysis, 
when combined as a single group they agree well with the results 
obtained from American waters.

In Table 16 is shown the total number of individuals marked at 
each station which were taken in each region, together with the 
average time en route. This combines the totals and averages 
developed in Tables 5 to 14.
