Density-dependent migratory waves in the marine pelagic ecosystem
(Journal article; Peer reviewed, 2006-11)The migration of large aggregations of animals that sweep through the landscape is a phenomenon with large consequences in many ecosystems. It has been suggested that such migrations are mediated by resource depletion. ... -
Density-independent mortality at early life stages increases the probability of overlooking an underlying stock-recruitment relationship
(Peer reviewed; Journal article, 2021)Abstract Beverton and Holt’s (1957) monograph contributed a widely used stock–recruitment relationship (BH-SRR) to fisheries science. However, because of variation around a presumed relationship between spawning biomass ... -
Density‐ and size‐dependent mortality in fish early life stages
(Journal article; Peer reviewed, 2019)The importance of survival and growth variations early in life for population dynamics depends on the degrees of compensatory density dependence and size dependence in survival at later life stages. Quantifying density‐ ... -
Depletion of coastal predatory fish sub-stocks coincided with the largest sea urchin grazing event observed in the NE Atlantic
(Peer reviewed; Journal article, 2020)In this contribution, we propose fishery driven predator release as the cause for the largest grazing event ever observed in the NE Atlantic. Based on the evolving appreciation of limits to population connectivity, published ... -
Depth and latitudinal gradients of diversity in seamount benthic communities
(Peer reviewed; Journal article, 2022)Latitudinal and bathymetric species diversity gradients in the deep sea have been identified, but studies have rarely considered these gradients across hard substratum habitats, such as seamount and oceanic island margins. ... -
Depth distribution of the amoebic gill disease agent, Neoparamoeba perurans, in salmon sea-cages
(Journal article; Peer reviewed, 2015-07-16)Identifying where and when parasites occur in farming environments is vital to understand transmission dynamics and develop preventative measures that reduce host-parasite encounters. A major parasite concern for Atlantic ... -
Depth-dependent target strengths of gadoids by the boundary-element method
(Journal article; Peer reviewed, 2003)The depth dependence of fish target strength has mostly eluded experimental investigation because of the need to distinguish it from depth-dependent behavioral effects, which may change the orientation distribution. The ... -
Deriving condition indices from standard fisheries databases and evaluating their sensitivity to variation in stored energy reserves
(Journal article; Peer reviewed, 2004)To evaluate interstock differences in condition, it would be advantageous to develop stock-level condition indices from standardized databases on weight and length. This study describes a method for estimating stock-level ... -
Descent and mixing of the overflow plume from Storfjord in Svalbard: an idealized numerical model study
(Journal article; Peer reviewed, 2008)Storfjorden in the Svalbard Archipelago is a sill-fjord that produces significant volumes of dense, brine-enriched shelf water through ice formation. The dense water produced in the fjord overflows the sill and can reach ... -
Description of a new goatfish species, Upeneus randalli n. sp. (Mullidae), from the Persian Gulf, with remarks and identification keys for the genus Upeneus
(Journal article; Peer reviewed, 2011-09)The number of species of the goatfish genus Upeneus from the western Indian Ocean has increased considerably due to recent taxonomic efforts. Here we describe a new species, Upeneus randalli n. sp., based on body and fin ... -
Description of the unusual digestive tract of Platax orbicularis and the potential impact of Tenacibaculum maritimum infection
(Peer reviewed; Journal article, 2020)Ephippidae fish are characterized by a discoid shape with a very small visceral cavity. Among them Platax orbicularis has a high economic potential due to its flesh quality and flesh to carcass ratio. Nonetheless, the ... -
Designing and evaluating length–frequency surveys for trap fisheries with application to the southern rock lobster
(Journal article; Peer reviewed, 2001)A survey design for estimating the length distribution of harvested southern rock lobsters (Jasus edwardsii) was developed for the South Australian fishery. Experimental sampling was carried out by volunteer fishers in ... -

Detecting Atlantic herring by parametric sonar
(Journal article; Peer reviewed, 2010-03-17)The difference-frequency band of the Kongsberg TOPAS PS18 parametric sub-bottom profiling sonar, nominally 1–6 kHz, is being used to observe Atlantic herring. Representative TOPAS echograms of herring layers and schools ... -
Detecting significant retrospective patterns in state space fish stock assessment
(Peer reviewed; Journal article, 2023)Retrospective patterns are commonly investigated to validate fish stock assessment models. A widely applied measure for retrospective bias is Mohn’s ρ and corresponding retrospective plots. However, retrospective patterns ... -
Detection of a nodavirus-like agent in heart tissue from reared Atlantic salmon Salmo salar suffering from cardiac myopathy syndrome (CMS)
(Journal article; Peer reviewed, 1997-05-22)The present study shows that a nodavirus-like agent is associated with the lesions of cardiac myopathy syndrome (CMS), a disease of unknown etiology which affects reared adult Atlantic salmon Salmo salar. In archive ... -
Detection of growth zones in the eyestalk of the Antarctic krill Euphausia superba (Dana, 1852) (Euphausiacea)

Detection of nodavirus in seawater from rearing facilities for Atlantic halibut Hippoglossus hippoglossus larvae
(Journal article; Peer reviewed, 2007-01-18)We used (1) ultracentrifugation followed by RT-PCR and (2) real-time RT-PCR to detect and quantify nodaviruses in seawater in which Atlantic halibut Hippoglossus hippoglossus larvae/fry had been held at rearing facilities. ... -
Detection of the myxosporean parasite Parvicapsula pseudobranchicola in Atlantic salmon (Salmo salar L.) using in situ hybridization (ISH)
(Journal article; Peer reviewed, 2015-02-15)Parvicapsula pseudobranchicola is a marine myxosporean parasite infecting farmed Atlantic salmon (Salmo salar). A major site for the parasite is the pseudobranch, which may be destroyed in heavily infected fish. Parvicapsulosis ...
