cially great quantity of large fish. This is more noticeable in some years than in others. 
Among the years considered, 1903 presents features of particular interest. We will 
therefore examine the measurements for this year, and especially those from the three 
localities investigated, viz. Svendsgrunden (the bank marked II in the chart Fig. 49). 
Rost, and Vestfjorden (West Lofoten). Fig. 60 gives an idea of the size of the skrei at 
these places in 1903; it will at once be noticed that there is a great difference between 
the three samples. In that from Svendsgrunden, the majority of the fish are under 70

cm., and almost the whole of the sample falls below the figure stated above as the average 
size, viz. 76.4cm. The sample from Rost is larger than the Svendsgrunden sample, but 
smaller than that from Lofoten; all three, however, exhibit an average below the nor- 
mal, the figures being 66.1, 72.8 and 74.2 cm. Comparing these, we may say that roughly 
speaking, the number of small fish increases from Vestfjorden out towards Rest, and 
still more farther out towards the northern bank. I may here observe that I shall at- 
tempt, in the following, to explain this as due to a great immigration in this year of small 
fish from the most northerly waters joining the skrei shoals and that the difference 
between the samples therefore was greater in 1903 than is usually the case. 
From these results it would seem, in my opinion, that it should be possible to form
