Ontogeny-Specific Skeletal Deformities in Atlantic Haddock Caused by Larval Oil Exposure
(Peer reviewed; Journal article, 2021)Bone deformities are one of the main effects of crude oil exposure in marine fish larvae. Craniofacial and jaw deformities, if severe enough, may restrict feeding and ultimately kill the developing larvae. This study aimed ... -
OpenDrift v1.0: A generic framework for trajectory modelling
(Journal article; Peer reviewed, 2018)OpenDrift is an open-source Python-based framework for Lagrangian particle modelling under development at the Norwegian Meteorological Institute with contributions from the wider scientific community. The framework is ... -
Operationalising ODEMM risk assessment for Integrated Ecosystem Assessment scoping: Complexity vs. manageability
(Peer reviewed; Journal article, 2023)Integrated Ecosystem Assessments (IEA) require consideration of the full suite of pressures and impacts affecting ecosystems. However, capacity limitations often severely limit our ability to do everything that we want or ... -
Operationalizing ensemble models for scientific advice to fisheries management
(Peer reviewed; Journal article, 2021)This paper explores the possibility of using the ensemble modelling paradigm to fully capture assessment uncertainty and improve the robustness of advice provision. We identify and discuss advantages and challenges of ... -
Operationalizing marketable blue carbon
(Peer reviewed; Journal article, 2022)The global carbon sequestration and avoided emissions potentially achieved via blue carbon is high (∼3% of annual global greenhouse gas emissions); however, it is limited by multidisciplinary and interacting uncertainties ... -
Operculum PIT tagging: a viable alternative to avoid human consumption in processed salmon
(Peer reviewed; Journal article, 2021)Passive integrated transponder (PIT) tags are commonly used to identify individual fish. However, use of PIT tags in commercial aquaculture research is limited by consumer safety concerns. For farmed fish, it is critical ... -
Opportunities for advancing ecosystem-based management in a rapidly changing, high latitude ecosystem
(Journal article; Peer reviewed, 2018)Unprecedented and rapid changes are ongoing in northern high latitude, marine ecosystems, due to climate warming. Species distributions and abundances are changing, altering both ecosystem structure and dynamics. At the ... -
Opposite selection on behavioural types by active and passive fishing gears in a simulated guppy Poecilia reticulata fishery
(Peer reviewed; Journal article, 2015) -
Optimal estimation of lice release from aquaculture based on ambient temperatures
(Peer reviewed; Journal article, 2020)Models for mapping and forecasting infective pressure from salmon louse Lepeophtheirus salmonis larvae are of major importance in the Norwegian government’s management of salmonid aquaculture. These models use site-reported ... -
Optimising delousing strategies: developing best practice recommendations for maximal efficacy and positive welfare - Final Report
(Rapport fra havforskningen;, Research report, 2023)The salmon aquaculture industry currently uses a range of strategies to combat salmon louse epidemics, however acute delousing methods are limited due to poor efficacy, poor welfare and environmental impacts, or potential ... -
Optimization of the Balance between Protein, Lipid and Carbohydrate in Diets for Lumpfish (Cyclopterus lumpus)
(Peer reviewed; Journal article, 2022)The aim of this study was to investigate how the dietary balance between protein, lipid, and carbohydrate affects growth, welfare, and health with focus on immune responses, in lumpfish of body weight ranges 1.7-10 g and ... -
Optimizing size selectivity and catch patterns for hake (Merluccius merluccius) and blue whiting (Micromesistius poutassou) by combining square mesh panel and codend designs
(Peer reviewed; Journal article, 2022)Gear modifications in fisheries are usually implemented to obtain catch patterns that meet management objectives. In the Basque bottom trawl fishery, gear regulations include the use of a square mesh panel (SMP) placed at ... -
Optimizing the use of quicklime (CaO) for sea urchin management — A lab and field study
(Peer reviewed; Journal article, 2020)Mass blooms of sea urchins sometimes cause kelp forest collapses that can last for decades. Quicklime has historically been used to reverse those conditions, but the efficacy of liming has varied along latitudinal and ... -
Orientation behavior and swimming speed of Atlantic herring larvae (Clupea harengus) in situ and in laboratory exposures to rotated artificial magnetic fields
(Peer reviewed; Journal article, 2020) -
Origin and expansion of the world’s most widespread pinniped: Range-wide population genomics of the harbour seal (Phoca vitulina)
(Peer reviewed; Journal article, 2022)The harbour seal (Phoca vitulina) is the most widely distributed pinniped, occupying a wide variety of habitats and climatic zones across the Northern Hemisphere. Intriguingly, the harbour seal is also one of the most ... -
Origin of marine invertebrate larvae on an Arctic inflow shelf
(Peer reviewed; Journal article, 2022)Many benthic invertebrate taxa possess planktonic early life stages which drift with water currents and contribute to dispersal of the species, sometimes reaching areas beyond the current ranges of the adults. Until recently, ... -
Ossification of Atlantic cod (Gadus morhua) – Developmental stages revisited
(Peer reviewed; Journal article, 2017)In studies of marine larvae, it is common to use days post-hatch as a developmental reference point. We show that age is a poor measure of morphological and physiological development in Atlantic cod. Therefore, we propose ... -
Other Effective Area-based Conservation Measures – OECMs: Andre effektive arealbaserte bevaringstiltak - Gjennomgang av noen norske arealbaserte fiskeriforvaltningstiltak og deres bidrag til bevaring av marin natur
(Rapport fra havforskningen;2023 - 45, Research report, 2023)I 2010 vedtok partsmøtet under konvensjonen om biologisk mangfold (CBD) bevaringsmål for natur der det blant annet het at 10% av hav- og kystområder skulle bevares innen 2020. Dette målet skulle kunne nås ad to veier: ... -
Otolith δ13C values as a metabolic proxy: Approaches and mechanical underpinnings
(Journal article; Peer reviewed, 2019)Knowledge of metabolic costs associated with maintenance, foraging, activity and growth under natural conditions is important for understanding fish behaviours and the bioenergetic consequences of a changing environment. ... -
Otolith “spawning zones” across multiple Atlantic cod populations: Do they accurately record maturity and spawning?
(Peer reviewed; Journal article, 2021)Specific changes identified in the otolith macrostructure of Northeast Arctic cod as “spawning zones” are presumed to represent spawning events, but recent experimental studies have challenged this relationship. Because ...
