A STUDY ON TROUT AND YOUNG SALMON. 235 



As examples from the hauls of this year my be quoted a 

 nights catch in the Beitstadfiord, illusti'ating the abundance of 

 trout. 



May 28, 1900. Kirknæsvaag. 



12 hauls with the eelhandseine from 9 pm. to 1 am. on the 

 strech Kirknæsvaag— Galgsøen, yielded: 



97 trout 19—58 cm. (total weight 45 kgr.). 



9 wrasse (labrus rupestris) 9 — 14 cm. 

 1 cod, 21 cm. 



1 PI. hmanda, 17 cm. 



10 Sprats, 12—15 cm. 



Ga. V4 barrel of herrings, 20 cm. 



In 1901 a few hauls with the seine were effected in Finmar- 

 ken and Nordland. A few hauls were also made in the Trond- 

 hjemsfjord. 



None of these experiments exhibited any difference from 

 the results of previous years, excepting a few of the hauls made 

 in Finmarken yielding specimes of sea-char. 



Tn October 1901 investigations were undertaken in Ihe 

 Mandal river. In this river, besides other southern rivers, the 

 population has asserted that large numbers of quite young sal- 

 mon during autumn ascended the river. 



The local name of these fishes is „biege" Mr. A. Land- 

 mark, inspector of fisheries, desired me to investigate this matter. 



Upon a closer examination of the lower parts of the Mandal 

 river however it immediately transpired, that the conditions in 

 this river were perfectly like those I had observed during autumn 

 in northern rivers. 



Thus 10 hauls with the seine at Lerkjær, Mandal river, 

 October 25, 1901, yielded : 



178 trout, 10—45 cm. 



5 young salmon (parr), 10 — 11 cm, long.
