ABSTRACT: Interannual variability of temperature in the Kola section (Barents Sea) and the abundance as 0-group (age 5 mo) and recruits (age 3 yr), spawning stock biomass, and survival of Arcto-Norwegian cod in the Barents Sea were related to climate
variability using a multivariate regression model. The results show that in the Barents Sea the temperature anomalies are significantly and highly correlated to climate variables such as large-scale sea-level pressure fields and the North Atlantic
Oscillation index. A significant and high correlation was detected between the temperature in the Barents Sea and both the 0-group index and recruitment of Arcto-Norwegian cod. A phase lag of 2 yr appears in recruitment. The high model skill and excellent
correlation indicate that it is possible to predict the future development of Arcto-Norwegian cod stocks from climate-change scenarios.
KEY WORDS: Climate variability · Cod recruitment · Barents Sea · Multivariate statistics
