Daily rations of cod from the Barents Sea
Dolgov, Andrey V.; Yaragina, Natalia A.; Ajiad, Adnan Mosa; Mehl, Sigbjørn; Bogstad, Bjarte (PINRO-IMR Symposium, Conference object, 1992)Diurnal feeding rhythms and daily diets of the North-East Arctic cod were investigated based on data obtained at several stations made in the summer of 1988-1989. A well-pronounced feeding rhythmicity was recorded under ... -
Density‐ and size‐dependent mortality in fish early life stages
Stige, Leif Christian; Rogers, Lauren; Neuheimer, Anna B.; Hunsicker, Mary E.; Yaragina, Natalia A.; Ottersen, Geir; Ciannelli, Lorenzo; Langangen, Øystein; Durant, Joel Marcel (Journal article; Peer reviewed, 2019)The importance of survival and growth variations early in life for population dynamics depends on the degrees of compensatory density dependence and size dependence in survival at later life stages. Quantifying density‐ ... -
Deriving condition indices from standard fisheries databases and evaluating their sensitivity to variation in stored energy reserves
Marshall, C. Tara; Needle, Coby L.; Yaragina, Natalia A.; Ajiad, Adnan Mosa; Gusev, Evgeny (Journal article; Peer reviewed, 2004)To evaluate interstock differences in condition, it would be advantageous to develop stock-level condition indices from standardized databases on weight and length. This study describes a method for estimating stock-level ... -

Direct and indirect climate forcing in a multi-species marine system
Ottersen, Geir; Stige, Leif Christian; Dalpadado, Padmini; Chan, Kung-Sik; Hjermann, Dag Ø.; Lajus, Dmitry L.; Yaragina, Natalia A.; Stenseth, Nils Christian (Journal article; Peer reviewed, 2010-10)Interactions within and between species complicate quantification of climate effects, by causing indirect, often delayed, effects of climate fluctuations and compensation of mortality. Here we identify direct and indirect ... -
Effects of climate and spawning stock structure on the spatial distribution of Northeast Arctic cod larvae
Endo, Clarissa; Vikebø, Frode Bendiksen; Yaragina, Natalia A.; Hjøllo, Solfrid Sætre; Stige, Leif Christian (Peer reviewed; Journal article, 2020)The spatial distribution of fish early life stages can impact recruitment at later stages and affect population size and resilience.
