Fig. 135 shows the composition in point of size of the Finmark samples; the 
dotted curve for June 1913, the fully drawn line for January 1914. 
I have already, in Chap. III. (p. 119 and Fig. 77) described the fluctuations in 
the stock of cod in Finmarken from May to June 1913. It will be remembered, 
that in May the Finmark stock consisted only of large fish (skrei) whereas on the 
Murman coast the fish were mostly small. In June, however, a change was apparent. 
The large fish moved eastward to the Murman coast, while fish from the eastern 
waters shifted over to Finmarken, so that the composition in point of age and size

---- from June 1913 and from January 1914. 
of the cod took the form of a curve with double summit, with a very small max- 
imum for the small loddefisk and a great maximum for the large skrei. (Figs. 77C. 
and 88, 3.) This is the position indicated by the dotted curve in Fig. 135. Looking 
next at the fully drawn line, we notice the interesting fact that both maxima have 
shifted to the right; i. e. the fish have grown larger, both as regards the group of 
small and that of the large fish. The numerical proportion between the two groups 
is almost unchanged, the small fish being somewhat more numerous, probably owing 
to the fact that their increased size renders them more liable to be captured by 
the lines; on the whole, however, the skrei far outnumber the others. This leads 
us to the definite conclusion that the stock in January 1914 is exactly identical with
