ARTIFICIAL FISH-HATCHING IN NORWAY. 

 By (I) G. M. Dannevig and (II) K. Dahl. 



The name of Captain G. M. Dannevig has been 

 associated with the artificial hatching of cod fry in 

 Norway for many years. The utility of the distribution 

 of such fry has been recently criticised by Dr. Hjort and 

 Mr. K. Dahl. I have asked Captain Dannevig and Mr. 

 Dahl to furnish me with brief accounts of recent experi- 

 ments and observations, each from his own point of view ; 

 and I print these below as likely to be of interest to 

 readers in this country.

Dear Sir, 



The investigations intended to solve the very much 

 disputed question as to the utility of planting artificially- 

 hatched cod fry in our fjords are now concluded, and 

 from my point of view the results are extremely 

 satisfactory. 



The facts are as follows : — 



The Sondeledfjord was investigated in the latter part 

 of September in the years 1903, 1904 and 1905, and the 

 Hellefjord in the beginning of October in the same years. 

 Cod fry were planted in the Sondeledfjord in the spring, 

 1904 and 1905, in all about 48 millions; and in the 

 Hellefjord in the spring of 1905, about 8 millions. 



The investigations as well as the planting of the fry 

 were controlled by Dr. Hjort's assistant, Mr. K. Dahl.
