Evidence for effects on the North Sea ecosystem due to varying oceanic inflow over the last 100 years
(ICES CM Documents;2002/Q:8, Working paper, 2002)Oceanic inflow is estimated to contribute more than 90% of the nutrient input into the North Sea (NSTF, 1993). Variability in the volume, chemical properties, biological content and source of the inflowing water is thus ... -
Exitomelita sigynae gen. et sp. nov.: a new amphipod from the Arctic Loki Castle vent field with potential gill ectosymbionts
(Journal article; Peer reviewed, 2011-11-02)The newly discovered deep-sea hydrothermal vent field ‘‘Loki’s Castle’’ at 2,350 m depth at 70 N on the Knipovich Ridge north of the island Jan Mayen is the only known black smoker field from the Arctic Ridge system. This ... -
Experiences in making acoustic measurements in a mesocosm with Calanus finmarchius
(ICES CM Documents;1997/FF:11, Working paper, 1997)In connection with a larger study of the effects of nutrification and turbulence on primary and secondary production, acoustic measurements have been made in the water volume defined by floating, vertically oriented, ... -
Exposure of cod Gadus morhua to resuspended sediment: an experimental study of the impact of bottom trawling
(Journal article; Peer reviewed, 2006-03-15)Bottom trawling activities resuspend large amounts of sediment and may be the main agent of sediment transportation in some areas. During periods of intensive fishing by large trawler fleets the high-turbidity environmental ... -
Factors affecting the parr-smolt transformation in Atlantic salmon
(ICES CM Documents;1979/M:2, Working paper, 1979)Factors affecting the parr-smolt transformation in Atlantic salmon (Salmo salar) are reviewed. The factors discussed are growth rate, temperature, photoperiod, salinity, food quality and quantity and hormones. Significance ... -
Faggrunnlag stillehavsøsters (Crassostrea gigas)
(Rapport fra Havforskningen;Nr. 32 - 2014, Working paper, 2014-12-16)Mapping and surveillance of the invasive species pacific oyster are important elements to be able to choose the right management decisions. Collecting of pacific oysters along the coast will be very expensive and can ... -
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. ... -
Fatty acids in harp seal blubber do not necessarily reflect their diet
(Journal article; Peer reviewed, 2011-03-28)The predator–prey relationship with respect to fatty acids (FAs) was studied in 57 harp seals Pagophilus groenlandicus and 16 potential prey species collected simultaneously in the northwestern Barents Sea in May–June 2006. ... -
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 ... -
Feeding habits of northeast atlantic harp seal (Phoca groenlandica) along the summer ice edge of the Barents Sea
(ICES CM documents, Working paper, 1989)Stomachs from 58 harp seals Phoca groenlandica from the northern parts of the Barents Sea were collected between August 20 and September 5 1987. Fiftysix of the stomachs contained identifiable contents. The amphipod ... -
Field and laboratory studies of herring larvae (Clupea harengus L.)
(ICES CM Documents;1979/H:28, Working paper, 1979)The present study deals with herring larvae from a local herring stock in Lindåspollene, north of Bergen. Growth and survival experiments of herring larvae in relation to density and type of prey organisms have been ... -

First detection of piscine reovirus (PRV) in marine fish species
(Journal article; Peer reviewed, 2012-01-24)Heart and skeletal muscle inflammation (HSMI) is a disease that affects farmed Atlantic salmon Salmo salar L. several months after the fish have been transferred to seawater. Recently, a new virus called piscine reovirus ... -
Fish and oil in the Lofoten–Barents Sea system: synoptic review of the effect of oil spills on fish populations
(Journal article; Peer reviewed, 2007-06-06)The Lofoten-Barents Sea area, which contains some of the most valuable fish stocks of the Atlantic Ocean, is being considered for offshore oil production. We review the effects of a hypothetical oil spill on fishes in this ... -
Fish behaviour during sampling as observed from free floating buoys - application for bottom trawl survey assessment
(ICES CM documents, Working paper, 1999)Varying fish distribution and behaviour during bottom trawl surveys has long been considered important for the reliability of survey abundance estimates. Size and species dependent behaviour may bias the estimates and ... -

Fisheries-induced selection as a driver of biodiversity change in exploited populations
(ICES CM documents;2007/E:17, Working paper, 2007)Today, fishing is the dominant source of mortality in most commercially exploited fish stocks. Life-history theory predicts that changes in mortality regime cause selection on life-history traits. In particular, increased ...
