or so of its second year. No special effort was made to secure the older fish, but when 
taken along with the younger fish they were measured and the data are included in 
Table 7. Table 8 and Figure 50 include the measurements of young fish only; that 
is, until an age of about 18 or 19 months is attained, as determined from Table 7. 
It is evident from Table 7 that it is a little difficult to separate the largest represen- 
tatives of the O class after they attain an age of 6 or 7 months from the I class, partly

because the two classes intergrade in size and partly because insufficient measure- 
ments of the larger fish are available. However, the average size given for the various 
months in Table 8 and Figure 50 must be nearly correct, as the larger fish, which may 
have been wrongly assigned as to the year class, are so few in number that the average 
could not have been affected greatly because of the error involved. While the 
maximum sizes given for the 0 class may be somewhat in error, it is believed, neverthe- 
less, that the average lengths shown for this year class are very nearly correct.
