236 KNUT DAHL. 



The smallest trouts were brownish, those above 20 cm, 

 shiny, quite like the trout I used to get during autumn in the 

 Gula and Orkla. These latter were by the people considered 

 as young salmon. 



b. Finemeshed hag nets. 



Fishing experiments with bag nets were effected in 1899, 

 1900 and 1901. 



In 1899 a bagnet was constructed of ^/12 cotton twine, 5V2 

 fathoms deep, 11 knots pr. foot (Norw.). The net was fixed in 

 a good bag-net locality at the island Garten, Ørlandet, in one 

 of our best bagnet districts. The net was fixed July 10 and 

 remanied in position (with larger or smaller intervals) until 

 August 9. 



The yield was: 



6 salmon, 58-64—69—65—70—52 cm. 



11 trout, 34-40-43-44—42—22-34—32—27-32—26 cm. 



19 cod, 30—80 em. 



11 seithe 30—40 cm. 



9,lythe 30—50 cm. 



1 hng 56 cm. 



2 lumpsucker 15 — 48 cm. 



During the winter 1899 — 1900 the same bagnet was em- 

 ployed at Inderøen through several mouths. Only one single 

 trout was cought, no salmon. 



In 1900 and 1901 a bagnet of hemptwine was used. The 

 mesh was 8 knots pr. foot (Norw.). It was fixed at the bio- 

 logical station, Hegdalen, Trondhjem and during the year 1900 

 it was fixed from July 1— September 28, with a few intervals. 



The yield was; 



4 salmon, 63—85-59—49,5 cm. 



5 trout, 42—40—32—36 cm. 

 392 lythe, 35—74 cm. 



13 seithe, 37—48 cm.
