It is very interesting to note how closely the recaptured fish agree, as regards their 
composition in point of size, with those set free. The average size of the fish set free 
at Lofoten was 76.8, that of the fish recaptured 77.3 cm., the average of all fish measured 
being 77.6. As regards Finmarken, the average size of the freed fish was 73.4, of those 
recaptured 77.1cm. There is a slight tendency towards a higher proportion of recap- 
_tures among the larger fish than among the smaller; taken on the whole, however, the 
similarity in point of size between the fish set free and those recaptured, appears remark- 
ably great. From this it may safely be concluded that the present material should be 
able to furnish some information as to the natural history of the cod. 
Fig. 68. Movements of 71 out of 460 skrei marked on the 1st April, 
of which 67 recaptured in April, 3 in May, and 1 in July. 
The marking experiments were commenced in East Lofoten on the 1st March, when 
100 skrei were returned to the water, part at one place and part at another (Fig. 63). 
The figure shows how these fish have spread eastward and westward over the Lofoten 
bank; east to Kanstadfjorden and west to Moskenes. Of these 100 fish, 23 were recap- 
tured as early as March; up to the 16th April inclusive, 31 had been retaken, since then 
however, no more have come to hand. 
On the 17th March, 63 fish were set free off Henningsvær, of which 17 were recap- 
tured by 21st April inclusive, none since (Fig. 64). On the same date, 86 fish were set 
free at the edge of the bank, of which 21 had been retaken by the end of April, one being 
found later, on the 20th of July, in Ostnesfjorden (Fig. 65). On the same date, also, 
at two other stations, (Fig. 66) 47 and 25, of which 16 recaptured in April. 
On the ist of April, 508 fish were set free on the bank outside Reine, of which 90
