Determinants of mean length at age of spring spawning herring off the coast of Hokkaido, Japan
(Journal article; Peer reviewed, 2008-08-29)The stock of Hokkaido spring spawning herring Clupea pallasii collapsed in the middle of the 20th century. In the first half of the 20th century, large amounts of spawning herring were caught by set nets at coastal ... -
Diel variations in photosynthetic activity of summer phytoplankton in Lindåspollene, western Norway
(Journal article; Peer reviewed, 1990-07-19)Diel patterns in photosynthesis of natural phytoplankton were studied during a 5 d period during midsummer in Lindbspollene, a land-locked fjord of western Norway. Samples were taken from depths of 0.5, 5, 10 and 21 m ... -
Diel vertical migration patterns in juvenile cod from the Skagerrak coast
(Journal article; Peer reviewed, 2010-04-29)We demonstrated a clear year-round diel vertical migration pattern (DVM) of small (26 to 45 cm) Skagerrak coastal cod Gadus morhua on a small geographic scale. Generalized additive models (GAMs) were used to make inferences ... -
Diel vertical movements determine spatial interactions between cod, pelagic fish and krill on an Arctic shelf bank
(Peer reviewed; Journal article, 2020)Predator-prey spatial interactions are essential to understand ecosystem processes like predation rates and trophic interaction strength. In marine systems, such spatial interactions are highly dynamic and difficult to ... -
Differential processing of yolk proteins during oocyte hydration in marine fishes (Labridae) that spawn benthic and pelagic eggs
(Journal article; Peer reviewed, 2002-07-18)The yolk proteins and free amino acids (FAA) were investigated during oocyte maturation in 4 species of Labridae with either benthic or pelagic eggs. Benthic eggs and oocytes of both types had a small FAA pool dominated ... -
Differential responses of three sympatric seabirds to spatio-temporal variability in shared resources
(Journal article; Peer reviewed, 2012-11-14)Environmental change linked to climate and human activities may affect top predators via the food chain in marine systems. Understanding the functional link between resources and predator responses (e.g. foraging effort, ... -
Disentangling the causes of maturation trends in exploited fish populations
(Journal article; Peer reviewed, 2007-04-16) -
Dissolved oxygen in contrasting estuaries of the Bay of Biscay: effects of temperature, river discharge and chlorophyll a
(Journal article; Peer reviewed, 2010-11-18)The effects of environmental factors on variations of dissolved oxygen (DO) saturation was assessed in 2 estuaries (Bilbao and Urdaibai) in the Bay of Biscay with contrasting hydrography and anthropogenic impact, for the ... -
Distribution of sex and age groups of ringed seals Pusa hispida in the fast-ice breeding habitat of Kongsfjorden, Svalbard
(Journal article; Peer reviewed, 2007-04-16)Spatial distribution of various age- and sex groups of ringed seals (N = 94; 19 adult males, 33 adult females and 42 subadults) was studied in their fast-ice breeding habitat in Kongsfjorden, Svalbard, during May 2004. ... -
Does the midnight sun increase the feeding rate and hence the growth rate of early juvenile Arcto-Norwegian cod Gadus morhua in the Barents Sea?
(Journal article; Peer reviewed, 2000-05-12)The growth rate of Arcto-Norwegian cod juveniles in the Barents Sea during their first 4 mo of life is about twice that of cod juveniles in areas farther south, such as Georges Bank and the Flemish cap. Cod larvae and ... -
Dose and dose-rate dependency in the mortality response of Calanus finmarchicus embryos exposed to ultraviolet radiation
(Journal article; Peer reviewed, 2003-02-04)In previous work, we reported that embryos of Calanus finmarchicus exposed to artificial ultraviolet-B (UV-B) radiation exhibited high wavelength-dependent mortality. The strongest effects occurred under exposures to ... -
Drift, growth, and survival of larval Northeast Arctic cod with simple rules of behaviour
(Journal article; Peer reviewed, 2007-10-11)Due to vertical variations in ocean circulation, larval Northeast Arctic cod Gadus morhua may influence their own drift routes by migrating vertically. By coupling a larval individual-based model and a general circulation ... -
Dynamics of shallow-water juvenile flatfish nursery grounds: application of the self-thinning rule
(Journal article; Peer reviewed, 2007-08-23)Annual development of density and mean weight of juvenile plaice Pleuronectes platessa was examined at 2 nursery grounds (Port Erin Bay, Isle of Man, Irish Sea and Admucknish Bay, Firth of Lorne, west coast of Scotland) ... -
Dynamics of the Norwegian Skagerrak cod: intuition vs inference
(Journal article; Peer reviewed, 2002-10-04) -
Earlier hatching and slower growth, a key to survival in the early life history of Norwegian spring spawning herring
(Journal article; Peer reviewed, 2018)Faster growth in fish larvae is often associated with enhanced survival, and here we investigated whether surviving juvenile Norwegian spring spawning herring Clupea harengus L. generally come from a pool of fast-growing ... -
Ecosystem model for evaluating potential cod production in a west Norwegian fjord
(Journal article; Peer reviewed, 1992-12-08)The carrying capacity for cod in a Norwegian fjord was analysed by means of a simulation model. Four age groups of cod were represented as well as the main prey groups labrids, gobies and benthic organisms. These groups ... -
Ecosystem-level effects of large-scale disturbance in kelp forests

Effect of food deprivation on distribution of larval and early juvenile cod in experimental vertical temperature and light gradients
(Journal article; Peer reviewed, 2013-02-14)How and when food limits the growth and survival of larval fish are essential questions which link oceanography and fisheries science, and theory suggests that food availability may affect survival through behavioural ... -
Effect of suspended sediments on the pumping rates of three species of glass sponge in situ
(Journal article; Peer reviewed, 2019)The largest known glass sponge reefs in Canada are within the Hecate Strait and Queen Charlotte Sound Glass Sponge Reefs Marine Protected Area (HSQCS-MPA) in British Columbia. However, human activities outside the core MPA ... -
