The fate of vitellogenic follicles in experimentally monitored Atlantic cod Gadus morhua (L.): Application to stock assessment
(Journal article; Peer reviewed, 2010-05)In this paper we report on the fate of vitellogenic follicles (VF) as either alpha atretic follicles (αF) or post-ovulatory follicles (POFs) using histology and captive Atlantic cod (Gadus morhua) in three experiments. In ... -

Fecundity and maturity of cod (Gadus morhua L.) from northern Norway
(ICES CM Documents;1988/G:28, Working paper, 1988)The fecundity was determined for cod caught during March 1986 and 1987 in the region Lofoten - Malangsgrunnen, northern Norway. No significant difference in fecundity appeared between the two years. -
Feeding and vertical distribution of cod larvae in relation to availability of prey organisms
(Conference object, 1979)The year-class strength of the Arcto-Norwegian cod stock varies on an annual basis by a factor of about 20:1 and is determined at the 0-group stage (about 1/2 year old cod). Since the number of eggs spawned far exceeds the ... -
Feeding of mature cod (Gadus morhua) on the spawning grounds in Lofoten
(Journal article; Peer reviewed, 2008-03-19)Many authors state that cod (Gadus morhua) do not feed during the spawning period. However, this more or less established fact has rarely been investigated in the field. Here, the content of stomachs from Northeast Arctic ... -
Fish migration in oscillating stratified water masses
(ICES CM documents, Working paper, 2006)Abstract Time series records from data storage tag (DST) attached on Northeast Arctic cod (Gadus morhua L.) and Greenland halibut (Reinhardtius hippoglossoides) are investigated in connection with hydrodynamic and ... -
Fisheries-induced evolution in cod
(ICES CM documents;2010/M:24, Working paper, 2010)Over the last eight decades, northeast Arctic cod has shown a marked change towards earlier maturation at smaller sizes. At the same time, harvesting shifted from primarily targeting mature cod in the spawning grounds to ... -

Forekomst og økologi til torsk, skrubbe, sjøørret og pelagisk fisk i Grenlandsfjordene
(Fisken og havet, Research report, 2000)Information on occurrence and feeding ecology of cod (Gadus morhua), flounder (Platichtys Jesus), anadromous brown trout (Salmo trutta), and epipelagic fish in the Grenland fjords (SE Norway) is reviewed. Emphasis in ... -

Fuel and metabolic scaling during the early life stages of Atlantic cod Gadus morhua
(Journal article; Peer reviewed, 2002-11-13)The simultaneous effect of temperature (5, 7, 10 and 13degreesC) and light on the rates of oxygen consumption and ammonia excretion of larval and early juvenile Atlantic cod Gadus morhua was examined. Larvae increased their ... -
Fullskalaforsøk med fangst, føring og levering av levende torsk
(Fisken og havet, Research report, 2003)Technology developed in the early nineties for catch, transport and delivery of alive, wild cod was used during a full-scale experiment March-May 2001. A total of about 200 tons of cod was delivered alive. The experience ... -
Genetic studies on released and recaptured cod in a fjord system
(ICES CM Documents;1992/G:65, Working paper, 1992)The study reported here is part of a more extensive investigation on the effects of mass rearing and release of 0-group cod in fjords and coastal areas in Norway. Each year since 1987 pond produced cod have been liberated ... -
