Assessing growth of Northeast Arctic cod by a bioenergetics model
(ICES CM Documents;1996/G:16, Working paper, 1996)This paper represents an attempt to elucidate how fish body size differences and metabolic costs alter the relationship between growth and consumption using a bioenergetics model. The results show that the daily growth ... -

(ICES CM Documents;1995/N:19, Working paper, 1995)Ecological studies of the Northeast Atlantic minke whale (Balaenoptera acutorostra) were carried out during spring (mainly April-May), summer (June-July) and autumn (AugustSeptember) in 1993 and 1994. Four small-type ... -
Diet of polar cod, Boreogadus saida, in the Barents Sea related to fish size and geographical distribution

Fatty acid composition as indicator of food intake in cod larvae (Gadus morhua L.) from Lofoten, northern Norway
(ICES CM Documents;1987/L:31, Working paper, 1987)The year class strength of the Arcto-Norwegian cod is mainly determined during the early life stages. The mortality is caused both by starvation and predation which are linked to environmental factors during this period. ... -
Feeding conditions of north-east Arctic (Arcto-Norwegian) cod larvae compared to the Rothschild-Osborn theory on small-scale turbulence and plankton contact rates
(ICES CM Documents;1989/G:19, Working paper, 1989)Data on first feeding North-east arctic cod larvae in Lofoten, sampled during the period 1976 - 1984, are examined to verify the theory on the influence of microturbulence on the contact rate between predator and prey ... -
Field studies of harp seal (Phoca Groenlandica) distribution and feeding ecology in the Barents Sea in september 1990
(ICES CM Documents;1991/N:3, Working paper, 1991)The harp seal Phoca groenlandica is the most abundant seal species in the Barents Sea, and it may be a significant predator on other marine resources in this area. In order to evaluate the ecological role of harp seals, ... -
Food and feeding habits of young saithe (Pollachius virens L.) on the coast of western Norway
(ICES CM Documents;1985/G:22, Working paper, 1985)The stomach contents of young saithe [Pollachius virens (L. )] (I- and II-group, mainly II-group) in two areas (A and B) on the western coast of Norway, has been analysed. When this juvenile saithe become two or mainly ... -
Getting fat in a hurry: food consumption during the feeding migration of NSS herring
(ICES CM Documents;2004/K:64, Working paper, 2004)The Norwegian spring-spawning (NSS) herring Clupea harengus inhabits a seasonal environment where food is abundant only during a short period of the year. During that period NSS herring store energy for metabolic ... -
Interannual variations in the liver condition index of cod as an indicator of temperature and feeding conditions in the Barents Sea
(ICES CM Documents;2001/V:31, Working paper, 2001)Background: Northeast Arctic cod, inhabiting the edge of the species area, experience variable environmental conditions and feeding resources, one of the main of them is capelin. Lipids are an important biochemical link ... -
Preliminary report from a comparative study of the diet of four gadoid fishes in a fjord of western Norway
(ICES CM Documents;1986/G:71, Working paper, 1986)As a contribution to a research program on sea ranching of cod in a fjord in western Norway, a dietary analysis of the main gadoid species has been conducted. The main aim of the analysis has been to identify potential ... -
