Fig. 75. Composition in point of size of the Finmark fish 
in different years. 
these falls nearly at the point of 
intersection of the two curves. 
This also indicates that the Fin- 
mark stock consists of two parts, 
the skrei group or mature fish, 
and the immature individuals. 
For the sake of convenience, we 
may in the following refer to 
those two groups of Finmark fish 
as the loddefisk group and the 
skrei group respectively, fixing the 
dividing limit at 65 cm. length *). 
This limit does not, as will be 
seen from the skrei curve, exactly 
coincide with the dividing line 
between mature and immature 
fish; there are also doubtless some 
skrei among the loddefisk; it is 
however, difficult to find any 
better definition, as any attempt 
at such must of necessity be of an 
arbitrary nature. 
Size of the Finmark fish in 
| different years. 
The table on p. 115 shows the 
size of the Finmark fish in the 
different years as far as known. 
This being a point of considerable 
importance, I have also added, 
(Fig. 75) a graphical representation 
of the same, while the following 
little table will serve to give a 
rough survey of the more salient 
features, including as it does the 
relative numbers of the larger 
groups. The tables and the figure 
reveal considerable fluctuations in 
the size of the Finmark fish from 
year to year, both as regards the 
averages and also within the 
*) In the following figures this limit 
is marked by a dotted vertical line, 
which for the sake of convenience is 
placed at the 65—69 cm. group in 
stead of a little to the left of same.
