The 11, year old fish have not been classified by investigation as to age, and may 
possibly include some slightly older mdividuals; Damas places the average at 15.1. 
In August 1907, a number of hauls were made in the Barents Sea with a fine-meshed 
trawl, the fish taken being chiefly 244,—41% years old. The composition in point of size 
has already been given; the following table shows a comparison between the composition 
of the sample in point of size and that in regard to age”).

By comparing this table with the previous one, we find the following average sizes 
for different ages of small cod.

This also agrees with the growth measurements undertaken by examination of the 
scales. An especially characteristic feature is the slow growth in the first two years. 
The table further shows that there is considerable variation, not only in the com- 
position with regard to size, but also in that in point of age, among the young cod, some 
year classes being richer than others. Thus we find 55 % of 3% year old fish, as against 
17.5 and 22 of the 2% and 4% year old respectively. We have already noticed, that 
the catches made with the fine-meshed trawl in 1905 and 1913 consisted chiefly of one 
year old fish. 
Growth and age of the loddefisk. 
If we now turn to the loddefisk, we may here first of all compare the composition 
in point of age with that in regard to size, in a similar manner to the comparison of the 
small cod, selecting for the purpose a table based on a sample of 654 fish, analysed by 
Dr. Damas**). 
The average sizes given by Damas are as follows:

*) This table has been compiled from the same sample dealt with by Damas on p. 120 of his 
paper. As his results did not agree with those of my own investigations, I examined the sample 
again, and found that all the statements of age in the table given by Damas on p. 120 were one 
year too low. In the course of subsequent correspondance on the subject, Dr. Damas authorised 
me to state that he agrees with my view, and that an error has arisen in his table during printing.
