It is quite probable that the migration of a number of herring to the Tersky coast, beyond 

 the borders of Kandalaksha Bay at the end of the spawning period of 1954, was conditioned by the 

 large size of these herring, since the six-year-old specimens formed the prevalent age -group 

 among the fishes tagged in 1954. 



Deductions 



1 . The method of tagging herring that has been developed by the Polar Institute proved 

 fully effective. The herring endure the tagging operation satisfactorily and develop quite normally 

 following tagging. Several specimens were recaptured 1.5-2 years after tagging. The tags are 

 clearly seen even in large catches . 



2. The tagging of White Sea herring showed that during the feeding season these fish migr- 

 ate from the arm of Kandalaksha Bay to Tersky coast. 



3. The high return of tagged herring confirmed the theory that White Sea herring are not 

 numerous .
