A STUDY ON TROUT AND YOUNG SALMON. 231 



Much time and labour was there upon spent in investigating 

 the shores of the fiord Gulosen in order to ascertain, if the 

 young emigrating salmon (smolts) also were to be found along 

 the shores of this fiord. 



All attempts at fishing the small salmon in these localities 

 however gave a negative result. From Mule on the east side 

 to Lundenaes on the westeren shore I fished in nearly all places 

 where a seine could possibly be employed, without being able 

 to find one single young salmon among the hundreds of trout 

 of all sizes wich were cought. 



These fishing experiments to me clearly established 

 two facts. ' 



None of the young salmon (smolts) wich I cought in the 

 rivers Gula and Orkla exceeded 16 cm. in length, and this latter 

 size did only occur as an exception. Generally their size did 

 not exceed 13 cm. 



Young salmon (smolts) larger than these I was unable to 

 procure. In Tab. no. IV will be found a graphical represen- 

 tation of their size. 



They were all shiny and evidently in their migratory attire, 

 such as it is well known and described by previous investigators. 

 These young were consequently on the point of emigrating. 



My failures in catching them outside the river might have 

 two reasons. Perhaps they had not yet emigrated from the 

 river mouths or estuaries, or perhaps in emigrating they did not 

 tuch the places wich I could control with my fishing gear. 



The occurence of the more or less "spotted trout was en- 

 tirely different. They could be obtained in alle sizes in the river. 

 Along the shores of the fiord all sizes from the migration stage 

 and upwards were obtained in every houl. 



In Tab. no. V column 1, 2, 3 the sizes cought during this 

 fishing period will be found represented. 



Next I sailed back to Orkedalsøren where a few days were 

 spent in controlling the correctness of my previous researches.
