A holistic and comprehensive data approach validates the distribution of the critically endangered flapper skate (Dipturus intermedius)
(Peer reviewed; Journal article, 2023)Morphological similarities between skates of the genus Dipturus in the north-eastern Atlantic and Mediterranean have resulted in longstanding confusion, misidentification and misreporting. Current evidence indicates that ... -
Atlantic mackerel (Scomber scombrus) change skin colour in response to crowding stress
(Peer reviewed; Journal article, 2021)Wild capture can be stressful for fish. Stress has the potential to induce mortality in released unwanted catches or negative flesh quality consequences in retained ones. Such effects compromise sustainable natural resource ... -
Consistent melanophore spot patterns allow long-term individual recognition of Atlantic salmon Salmo salar
(Peer reviewed; Journal article, 2017) -
Development stage distribution as a proxy for feeding success and growth for first feeding Norwegian spring spawning herring larvae
(Peer reviewed; Journal article, 2020)The estimation of growth rates in young herring larvae (Clupea harengus) in the field can be difficult because the primary increments in the otoliths may not be discernible or formed at a daily level. Likewise, the estimation ... -
Differences in growth and survival between cod Gadus morhua and herring Clupea harengus early stages co-reared at variable prey concentrations
(Journal article; Peer reviewed, 2015-09-28)It was hypothesized that the survival and growth strategies of herring Clupea harengus, displaying a flexible reproductive activity, are adapted to coping with longer periods of prey deprivation (i.e. more variable prey ... -
Environmental change influences the life history of salmon Salmo salar in the North Atlantic Ocean
(Peer reviewed; Journal article, 2016)Annual mean total length (LT) of wild one-sea-winter (1SW) Atlantic salmon Salmo salar of the Norwegian River Imsa decreased from 63 to 54 cm with a corresponding decrease in condition factor (K) for cohorts migrating to ... -
First estimates of metabolic rate in Atlantic bluefin tuna larvae
(Peer reviewed; Journal article, 2020)Atlantic bluefin tuna is an iconic scombrid species with a high commercial and ecological value. Despite their importance, many physiological aspects, especially during the larval stages, are still unknown. Metabolic rates ... -
From gametogenesis to spawning: How climate-driven warming affects teleost reproductive biology
(Peer reviewed; Journal article, 2020)Ambient temperature modulates reproductive processes, especially in poikilotherms such as teleosts. Consequently, global warming is expected to impact the reproductive function of fish, which has implications for wild ... -
Gill area explains deviations from body size–metabolic rate relationship in teleost fishes
(Peer reviewed; Journal article, 2022)Whether gill area constrains fish metabolism through oxygen limitation is a debated topic. Here, the authors provide insights into this question by analysing mass-specific metabolic rates across 44 teleost fishes extracted ... -
A holistic and comprensive data approach validates the distribution of the critically endangered flapper skate (Dipturus intermedius)
(Peer reviewed; Journal article, 2023)Morphological similarities between skates of the genus Dipturus in the north-eastern Atlantic and mediterranean have resulted in longstanding confusion, misidentification and misreporting. Current evidence indicates that ... -
Influence of experimental set-up and methodology for measurements of metabolic rates and critical swimming speed in Atlantic salmon Salmo salar
(Journal article; Peer reviewed, 2019)In this study, swim‐tunnel respirometry was performed on Atlantic salmon Salmo salar post‐smolts in a 90 l respirometer on individuals and compared with groups or individuals of similar sizes tested in a 1905 l respirometer, ... -
Influence of photoperiod and protocol length on metabolic rate traits in ballan wrasse Labrus bergylta
(Peer reviewed; Journal article, 2021)In this study, ballan wrasse Labrus bergylta were subjected to either a conventional 1-day or an extended 5-day respirometry protocol. Additionally, in the 5-day protocol the fish were subjected to a 12 h light–dark cycle ... -
Isotopic turnover of polar cod (Boreogadus saida) muscle determined through a controlled feeding experiment
(Peer reviewed; Journal article, 2023)Polar cod (Boreogadus saida) is an important trophic link within Arctic marine food webs and is likely to experience diet shifts in response to climate change. One important tool for assessing organism diet is bulk stable ... -
Lemon sole Microstomus kitt in the northern North Sea: a multidisciplinary approach to the early life-history dynamics
(Peer reviewed; Journal article, 2021)Lemon sole Microstomus kitt is a commercially valuable flatfish species that occurs in shelf waters around the northeast Atlantic. Only the most basic life-history information is available for the North Sea. Spawning is ... -
Modelling and interpreting fish bioenergetics – a role for behaviour, life-history traits, and survival trade-offs
(Journal article; Peer reviewed, 2016-01-14)Bioenergetics is used as the mechanistic foundation of many models of fishes. As the context of a model gradually extends beyond pure bioenergetics to include behaviour, life-history traits and function and performance of ... -
Movement patterns of temperate wrasses (Labridae) within a small marine protected area
(Peer reviewed; Journal article, 2021)The movement patterns of three commercially important wrasse (Labridae) species inside a small marine protected area (~ 0.15 km2) on the west coast of Norway were analysed over a period of 21 months. The mean distance ... -

Notes on age determination, size and age structure, longevity and growth of co-occurring macrourid fishes
(Peer reviewed; Journal article, 2021)Nineteen species of the deep-water fish family Macrouridae inhabit the Mid-Atlantic Ridge (MAR) of the North Atlantic. Size and age structure, longevity and length at age were explored for seven of the more abundant species: ... -
Of three sharks and one chimaera: varied habitat preferences across a latitudinal range revealed by coastal and offshore surveys
(Peer reviewed; Journal article, 2021)Using national and international research survey data and applying a combination of models and mapping tools, this study revealed temperature and depth as the crucial environmental drivers of both the distribution and the ... -
