Percentage of fish recaptured. 
We will first of all consider the numbers of the fish set free and recaptured, as shown 
in the following table.

For East Lofoten, the percentage of skrei recaptured varies, as will be seen, from 
22 to 31, averaging 26.8%. More than every fourth fish was here recaptured. 
For West Lofoten, the percentage of recaptures off Reine was between 15 and 18%; 
average of all three samples 14.1 %, or about every seventh fish. From Rost, only 0.4 % 
were recaptured, the percentage of all recaptures being thus reduced to 11.6 %. 
In comparing these percentages for the different parts of the Lofoten waters, how- 
ever, it must be borne in mind that the experiments were not all carried out simultane- 
ously. The East Lofoten fish were set free in March, those from West Lofoten during 
the first half of April, and those from Rest in the latter part of that month. The fishing 
season was thus farther advanced when the western fish were marked and freed, their 
chances of escape being thus proportionally increased. The Rost markings were carried 
out during the last few days of the fishing season, so that the probability of recapture 
was here particularly slight. In considering the percentage of recaptures, it is also neces- 
sary to remember that in all probability, not all the fish recaptured were reported to 
the authorities. In several cases, the silver mark was first discovered on the dried head. 
Moreover, a number of the marked fish may have died in the meantime. Inasmuch as 
it is possible, therefore, to draw any conclusions from the number of fish recaptured, 
we may probably accept the results of the experiments along the range from Hela to 
Reine during the period from 1st March to ist April, according to which, every fourth 
or fifth specimen was recaptured. 
Migrations. 
If we then proceed to consider the information at hand with regard to the move- 
ments of the fish, we find, especially from the East Lofoten experiments, that the fish 
spread eastward and westward over the bank. Starting from Hola in East Lofoten, 
some have moved to Moskenes, others to Kanstadsfjorden on the east, and similarly 
also from Henningsver. From here a number also moved to Vere and Rost. In the 
western Lofoten waters, the fishery was particularly intense about the beginning of
