that the number of fry had largely increased in the 

 Sandnesfiord as well as the Stoleflord.* 



These diagrams indicate the conclusion that when 

 there is a scarcity of fry, this scarcity is common to a large 

 stretch of coast, and ivlien there is an abundance of fry, this 

 abundance may be observed everywhere within a certain large

area. The addition of artificially hatched cod larvae to a 

 locality seems nowhere to influence the relative abundance of 

 littoral fry in a recognisable degree. 



These facts, of which I have here briefly drawn the 

 main outlines, seem to me to leave little hope as to the 

 possibility of carrying out a fish culture, or locally 



* The investigations in Sept. -Oct. in the Sondeledfiord and in the 

 Hellefiord were made with a more coarse-meshed seine than mine. 

 This seine (Mr. Dannevig's seine, see page 111) must have let nearly 

 all the very small fry (under G-7 cm.) pass through the meshes, the 

 cloth in the middle being then removed In July-August the seines 

 fish about alike. The results from autumn may thus in these two 

 fiords not directly be compared to the autumn results in the Sandnes 

 and Stole fiords. Both of these were examined with my seine, which 

 could catch all sizes.
