year. In each case, the average weight (whole) is given for each 5cm. group, as also 
the average weight of liver and the proportion between the weight of the liver (i. e. the 
percentage of liver). 
In both samples, the average weight of liver is seen to increase with increasing length 
and weight of the fish; in the Lofoten sample, the increase from the 60—64 cm. group 
to that of the 115—119 cm. fish amounts to as much as 3,000 %. In both samples, more-

over, it is distinctly evident that the weight of the liver increases not only in proportion 
to the weight of the fish, but at a far higher rate. 
In the Lofoten samples, the weight of liver in the 65—67 cm. fish amounted to 1.2 % 
of the weight of the fish, whereas the corresponding percentage for the largest indivi- 
duals was 5.6%. Equally rapid is the increase noted in the case of the Finmark 
fish. The larger the fish, the higher is the percentage of liver contained. One point of dif- 
ference is noticeable between the two samples, all the weights, both of fish and liver, 
being lower in the case of the Lofoten fish than in those from Finmarken. This can 
only be explained as due to the fact that the Lofoten skrei were then spent, the fat from 
the whole of the system, muscles and liver, having been consumed in the process of devel-
