separately. As these fish feed in the Strait of Georgia and adjacent waters throughout 

 the period of their marine life and as they wander about in this area, it follows that 

 only when spring salmon are caught in the rivers or as they are entering the rivers, 

 can one have any assurance in this area as to the river system to which they belong. 



The total number examined was 527, of which 412, or T8-2 per cent were of the 

 sea type and 115, or 21 -S per cent of the stream type. Of the sea type, 35 were in 

 their fifth year (&-5 per cent), 142 in the fourth year (34-5 per cent), 203 in the 

 third year (49-2 per cent) and 32 in the second year (7-8 per cent). Of the stream 

 type, 4 were in their sixth year (3-5 per cent), 26 in the fifth year (22-6 per cent), 

 50 in the fourth year (43-5 per cent) and 35 in the third year (30-4 per cent). (As 

 in previous years many of the fish were immature and hence these percentages give no 

 indication of the relative numbers that mature in each year). 



In both types the females outnumbered the males as indicated in the following

Although the data are not suitable for determining definitely the relative growth 

 of male and female fish it may be worth while to give the lengths of each type and 

 year to indicate the limits of each. The lengths are given in inches.
