| dc.description.abstract | The model presently in use for management of the Barents Sea capelin stock
may be considerably improved by utilization of biological information from the
spawning stock. The distributions of length and age for capelin during it's
spawning migration exhibit considerable geographical variation. Previously, it
was not possible to construct reliable length and age distributions based on
direct measurements for the spawning stock. The present paper seeks to
develop a method for estimating the geographical distribution of the spawning
migration, once the initial distribution and the sea temperature is known. To
do this, a theory for spawning migration is developed, and the east-west
component of the migration pattern is estimated. Possible relationships
between the estimated migration and the sea temperatures at onset of
migration and sea temperatures at the end of migration are discussed. | en |
