KNUT DAHL. 



I found nothing to contradict my above mentioned experiences, 

 after this the whole fiord was examined from June 18 to August 

 11. I first examined the outer part of , the fiord right out to 

 Storfosen and the Biugn fiord. Thence I returned examining 

 the whole of the Trondhjem fiord right to the bottom of the 

 Beitstad fiord. 



Fishing experiments were thus carried out in the following 

 localities: Lensviken, Rissen, Selven, Ørlandet, Storfosen, Biugn, 

 Tautra, Aasenfiord, Frosten, Holsanden, Levanger, Sundnæs, 

 Borgenfiord, Vennæs, Kirknæs and Krogsvaag. 



Several hundred houls with the seines were effected in these 

 localities. 



Not one single young salmon (smolt) or grilse was cought, 

 while trout in all stages, excepting those which only belong to 

 the rivers, were abundant. From August 13 to August 17 

 the Gula, the mouth of the Gula and the Gulosen were again 

 investigated. 



We here recorded the same phenomena as were found 

 earlier in the summer. 



By way of example I quote the journal: 



„The mouth of the Gula. August 16. 



6 Hauls with the eelhandseines yielded: 



More than 500 flounders. 



Some Herring fry. 



19 Trout 10—40 cm. 



37 Young salmon 9 — 13 cm." 



„Gula August 17. 



11 Hauls with the eelhandseines from the Uddevold bridge 

 to the river mouth yielded: 



84 trout 10—38 cm. 



11 young salmon 10 — 13 cm." 



It was thus evident, that the smolts had not grown and 

 that they consequently emigrated at the above mentioned size.
