78 Angling Travels in Norway. 



and I am of opinion that it is impossible for them to 

 shed their ova, or milt, in late autumn, then to visit the 

 sea in early spring, and return to the river in June or 

 July, having in the interim traversed two hundred miles, 

 regained about 5 lbs. lost in the kelt stage, and have 

 accumulated an additional increase in weight of 5 lbs. at 

 the least. 



If Salmo salar can spawn annually under such con- 

 ditions as these, he must pass the majority of his days in 

 racing up and down the river and fjord. 



Some instances have been recorded of fish marked 

 as kelts in spring having been recaptured as fresh-run 

 fish in autumn, but this would be impossible in rivers 

 which aftbrd insufticient water for an autumn "run." 



The conclusions I arrive at are — 



(1) That salmon which have spawned in pools which 



in the autumn have open communication with 

 the fjord or sea, may, and frequently do, 

 return to the sea after spawning and before 

 winter, and under such conditions may very 

 well spawn each year. 



(2) That salmon which have spawned in situations 



from which no departure is possible until the 

 following spring, may spawn each year, pro- 

 vided that their river admits of an autumn 

 " run."
