A review of the battle for food in the Barents Sea: cod vs. marine mammals
(Journal article; Peer reviewed, 2015-03-25)Cod, harp seal and minke whale are the main top predators in the Barents Sea ecosystem. In the last decade, the abundance of cod has increased considerably, and is at a record high level. In spite of this, the growth and ... -
A review of the distribution, migrations, food, reproduction, exploitation and present abundance of humpback whales (Megatera novaeangliae) in the northeast Atlantic
(ICES CM Documents;1990/N:10, Working paper, 1990)Most available knowledge about northeast Atlantic humpback whales (Megaptera novaeangliae) is based on information and experience gained during the pioneer period of modern whaling in Norwegian waters in 1868-1904 when ... -
A set of Single Nucleotide Polymorphism (SNP) loci for generic distinction between Norwegian farm and wild Atlantic salmon (Salmo salar L.).
(ICES CM documents;2009/Q:01, Working paper, 2009)Atlantic salmon breeding programs were first established in Norway in the late 1960´s. Since then, production of farm salmon has steadily increased, and represents the economically most important aquaculture industry in ... -
A shift in a hake (Merluccius merluccius) population of the NW Mediterranean induced by a combined effect of climate and fishery harvesting
(ICES CM documents;2009/F:04, Working paper, 2009)Climate and fisheries are often interacting with each other and producing complex synergic effects on the population dynamics of marine species. The drastic change in the climatic conditions in the North Atlantic (NA) ... -

A stripping method for Atlantic halibut (Hippoglossus hippoglossus L.)
(ICES CM Documents;1987/F:40, Working paper, 1987)A stripping-board was built and tested on a broodstock of halibut ranging from 8 to 150 kg body weight. The smooth surface of the neophrene mattress minimized the loss of mucus and reduced the stripping stress ... -
A study of genetic variation in northeast Atlantic harp seals (Pagophilus groenlandicus)
(ICES CM Documents;1991/N:5, Working paper, 1991)16 enzymes were examined for genetic studies of the harp seal population structure in the Northeast Atlantic. Muscle and liver samples were collected in the West Ice off Jan Mayen and in the Eastern Barents Sea in 1987, ... -
A unifying theory explaining different power budget formulations used in modern scientific echosounders for fish abundance estimation
(Fisken og Havet;7-2014, Research report, 2014-12-31)Acoustic methods used in fish abundance estimation constitute a key part of the analytic assessment that makes the basis for fisheries research and international regulations of marine resources. The methods rely on ... -

Abundance and distribution of 0-group Arcto-Norwegian cod and haddock 1965 - 1982
(PINRO-IMR Symposium, Conference object, 1984)The trawl data from the International 0-group fish surveys in the Baretns Sea are reanalysed for cod and haddock. Relative indices of yearclass abundance are estimated on a logarithmic scale. The most abundant yearclasses ... -

Abundance and mortality of Northeast Arctic cod and haddock during their first years of life
(ICES CM Documents;2010/C:04, Working paper, 2010)For Northeast Arctic cod and haddock in the Barents Sea, long time series of year-class abundance are available at several stages before they recruit to the fishery, i. e. before they reach age 3. Several studies have ... -
Abundance and productivity of the pelagic ecosystem along a transect across the northern Mid Atlantic Ridge in June 2003
(ICES CM documents;2008/C:12, Working paper, 2008)A research cruise was conducted into the Irminger Sea west and southwest of Iceland on the Icelandic vessel Árni Friðriksson, from 4-30 June 2003, investigating redfish, Sebastes mentella, other pelagic fishes, zooplankton, ... -
