SMOLTS 27 



19 and August 26 there were captured, between 

 Storholm and Brandasund, off the south coast of 

 Norway, forty-three salmon and 124 grilse. After 

 August 26 to the end of September, twenty-two sal- 

 mon and two grilse were obtained, giving a total of 

 191 salmon and gri]se. Three of the grilse were 

 small, viz., 46 cm., 46 cm., and 45 cm. (18 inches). 



In 1906 two fine-meshed mackerel nets were used 

 by Mr. Waage's men. One caught, between April 19 

 and August 26, twenty-three salmon and forty- seven 

 grilse, and five of the grilse were under 5 5 cm. (2 If in.), 

 viz., 37, 42, 42, 46, and 47 cm. After August 26, 

 twenty-seven salmon and four grilse were got, but 

 none of the latter were now under 55 cm. The other 

 net caught between July 3 and September 29 forty- 

 two salmon and grilse, but only one of the grilse was 

 under 55 cm. 



In contradistinction to these results in the open 

 sea, Herr Dahl points to the results of his fishing in 

 the southern fjords in 1903, 1904, and 1905. He 

 made 930 attempts with a fine-meshed net, and in 

 this time only caught one specimen of salmo solar 

 under 55 cm. 



His conclusion is that the young of the salmon, 

 after leaving the rivers and fjords, pass to the open 

 sea, and he declares that they occur constantly, and 

 can be freely caught if suitable nets are employed in 

 the natural habitats of young mackerel and herring. 



We have already seen that our Tay sparling net 



exneriments showed that the salmon smolts seemed 



i. 



to make a bolt for the open sea after leaving the 

 upper tidal water. We already know from the
