The effect of oceanographic conditiond on disrtibution and population dynamics of commerical fish stocks in the Barents Sea. Proceedings of the third Soviet-Norwegian Symposium. Murmansk, 26-28 May 1986. 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.
