2. If a program is to continue over a period 

 of more than 1 year, sampling should be done 

 in the same localities and the same time 

 periods each year. 



3. Larger scale samples than are custom- 

 arily taken for determining age in other 

 species of salmon are required. 



4. To eliminate the task of converting length 

 measurements, a single measurement, such as 

 mideye to hypural plate, should be taken in both 

 fresh- and salt-water samples. 



5. In view of the difficulty in interpreting 

 age from chum salmon scales, the problem 

 should be reviewed and methods standardized.
