118 A RIVER OF NORWAY 



Previous to 1902, when no record was kept 

 of net -marked grilse, I was under the impres- 

 sion that considerably more than half the grilse 

 killed were marked. Probably this was an 

 error, as in 1902 out of seventy-four grilse killed 

 in June and July only thirty-two had net- 

 marks. In 1903 out of 119 killed, forty-five 

 were marked. The proportion therefore seems 

 to be roughly about 40 per cent. 



It is a curious fact that for some days nearly 

 all the grilse caught will be net-marked ; these 

 days being preceded and followed by a period 

 when none will have such markings. For in- 

 stance, in 1903, from July 5th to 9th, seven- 

 teen grilse were killed of which not one was 

 marked. On the 22nd and 23rd of the same 

 month, of nine grilse seven bore markings. 

 The explanation of a particular school of grilse 

 being without marks may be that it has 

 passed the most heavily-netted portion of 

 the outer fjords during the weekly close time, 

 or perhaps that for some reason it has come 

 through in the deeper water away from the 

 shores.
