Interrelations between fish populations in the Barents Sea. Proceedings of the fifth PINRO-IMR Symposium. Murmansk, 12-16 August 1991.The Barents Sea capelin stock coliapsed during the period 1983-1986.
One of the main factors causing the colIapse was a rapid increase in
consumption of capelin by cod, caused by the strong 1983 cod year class.
Based on measurements of stomach evacuation ra+es in the appropriate
temperature interval and data from a combined Russian-Norwegian
stomach sampling programrne, predation mortalities are estimated by the
MR multispecies model for the Barents Sea - MULTCPEC. In order to
estimate these predation mortalities, cod-capelin interaction parameters
and yearly migration parameters for capelin are ako estimated
