while the small creeks where the hauls were made were covered with seaweed. 

 One hundred and six hauls were made each time and with the following result :

 1,523 yearlings; September, 1905, after planting, 1,133 yearlings. 



Fjord No. 2. — About i>^ miles long by one-third of a mile broad. Bottom 

 as in no. i . Many of the small creeks liberally covered with sawdust. Twenty- 

 one hauls each time, resulting as follows: September, 1903, before planting, 

 36 yearlings; September 1904, before planting, 133 yearlings; September, 1905, 

 after planting, 143 yearlings. 



Fjord No. 3. — Circular. Two and one-half miles long by i mile broad. 

 Bottom as no. i. Number of hauls 33, with following results: September, 1904, 

 before planting, 454 yearlings; September, 1905, after planting, 756 yearlings; 

 September, 1906, after planting, 953 yearlings. 



The main results for the three fjords will be: 



The increase amounts to 141 per cent. 



Figures taken from the fishery statistics for the Kristianiafjord, inside of 

 Dribak, begun in 1872, show an average catch of 75,761 cod in the period between 

 1872 and 1881, and of 58,476 between 1882 and 1891. In 1892, when fry first 

 were planted, the catch was 44,01 3. Since then there has been a steady increase, 

 and last year the number caught was 114,013. The number of fry planted in 

 the Kristianiafjord since 1892 is about 170,000,000, worth about 5,000 kroner, 

 while the increase in the catch over and above what it was in 1892 is worth 

 about 600,000 kroner. 



On the west coast of Norway, where hatching has not been conducted, the 

 cod is gradually disappearing from the fjords.
