The language of fishery management advice offered by ICES
(ICES CM documents, Working paper, 2003)Since the establishment of the Exclusive Economic Zones in the mid 1970s, several exploited fish stocks in the Northeast Atlantic have been managed by total allowable catch (TAC). The advice on annual levels of TAC, as ... -
Large annual variation in the amount of skipped spawning for female Northeast Arctic haddock Melanogrammus aeglefinus
(Peer reviewed; Journal article, 2020)Although the phenomenon of skipped spawning has been described in numerous fishes, time-series are scarce. We used the presence of post-ovulatory follicles in histological gonad slides from females not developing oocytes ... -

Large scale patches of Calanus finmarchicus and associated hydrographic conditions off the Lofoten archipelago
(Peer reviewed; Journal article, 2022)Large swarms of individuals at different spatiotemporal scales characterise the distributions of many animal species. In the ocean several mesozooplankton taxa aggregate in large patches or swarms driven by active behavioural ... -
Large scale patterns in vertical distribution and behaviour of mesopelagic scattering layers
(Journal article; Peer reviewed, 2016-01-27)Recent studies suggest that previous estimates of mesopelagic biomasses are severely biased, with the new, higher estimates underlining the need to unveil behaviourally mediated coupling between shallow and deep ocean ... -
Large scale release experiment of juvenile lobsters, Homarus gammarus, in Norway
(ICES CM Documents;1990/K:2, Working paper, 1990)A large scale spring release of juvenile lobsters, Homarus gammarus, was conducted at Kvitsøy, southwestern Norway in March 1990. The lobsters, 14,700 one and a half year old and 8,700 six months old, were tagged internally ... -
Large-effect loci mediate rapid adaptation of salmon body size after river regulation
(Peer reviewed; Journal article, 2022)Understanding the potential of natural populations to adapt to altered environments is becoming increasingly relevant in evolutionary research. Currently, our understanding of adaptation to human alteration of the environment ... -

Large-scale culturing of Neogloboquadrina pachyderma, its growth in, and tolerance of, variable environmental conditions
(Peer reviewed; Journal article, 2023)The planktic foraminifera Neogloboquadrina pachyderma is a calcifying marine protist and the dominant planktic foraminifera species in the polar oceans, making it a key species in marine polar ecosystems. The calcium ... -

Large-scale culturing of the subpolar foraminifera Globigerina bulloides reveals tolerance to a large range of environmental parameters associated to different life-strategies and an extended lifespan
(Peer reviewed; Journal article, 2024)The subtropical to subpolar planktic foraminifera Globigerina bulloides is a calcifying marine protist, and one of the dominant foraminiferal species of the Nordic Seas. Previously, the relative abundance and shell ... -
Large-scale patterns in community structure of benthos and fish in the Barents Sea
(Journal article; Peer reviewed, 2016-04-23)Biogeographical patterns have an ecological basis, but few empirical studies possess the necessary scale and resolution relevant for investigation. The Barents Sea shelf provides an ideal study area, as it is a transition ... -
Large-scale rearing of cod fry (Gadus morhua) in an inlet

Large-scale rearing of cod fry on the natural food production in an enclosed pond. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)For four years (1980-1983) populations of 5 day old cod larvae have been transferred to a dammed seawater pond (60 000 m^3 ). The water volume had been treated with rotenone in advance, and the larvae were released ... -

Large-scale salmon farming in Norway impacts the epiphytic community of Laminaria hyperborea
(Peer reviewed; Journal article, 2021)Large-scale finfish farms are increasingly located in dispersive hard-bottom environments where Laminaria hyperborea forests dominate; however, the interactions between farm effluents and kelp forests are poorly understood. ... -
Large-scale seabird community structure along oceanographic gradients in the Scotia Sea and northern Antarctic Peninsula
(Peer reviewed; Journal article, 2023)The Scotia Sea and Antarctic Peninsula are warming rapidly and changes in species distribution are expected. In predicting habitat shifts and considering appropriate management strategies for marine predators, a community-level ... -
Larval and small juvenile cod Gadus morhua concentrated in the highly productive areas of a shelf break front
(Journal article; Peer reviewed, 1995-09-14)The early life of cod was studied during a survey programme covering the northeastern North Sea, the Skagerrak and the Kattegat in May 1992. Our aim was to asses the interrelated effects of physical and biological factors ... -
Larval fish trophodynamic studies on Georges Bank: sampling strategy and initial results. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)A sampling strategy is outlined to serve as a framework for determining the fine- to micro-scale vertical disribution or fish larvae and their prey on Georges Bank in a single vessel, interdisciplinary mode of operation. ...
