Development stage distribution as a proxy for feeding success and growth for first feeding Norwegian spring spawning herring larvae
(Journal article; Peer reviewed, 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 ... -
First estimates of metabolic rate in Atlantic bluefin tuna larvae
(Journal article; Peer reviewed, 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 ... -
First recorded occurrence of the parasitic barnacle (Anelasma squalicola) on a Greenland shark (Somniosus microcephalus) in the Canadian Arctic
(Journal article; Peer reviewed, 2023)A solitary Anelasma squalicola specimen was collected from the cloaca of a Greenland shark (Somniosus microcephalus), the first time this association has been recorded. The specimen's identity was confirmed through ... -
Fishes in a changing world: learning from the past to promote sustainability of fish populations
(Journal article; Peer reviewed, 2018)Populations of fishes provide valuable services for billions of people, but face diverse and interacting threats that jeopardize their sustainability. Human population growth and intensifying resource use for food, water, ... -
Host choice and fitness of anemonefish Amphiprion ocellaris (Perciformes: Pomacentridae) living with host anemones (Anthozoa: Actiniaria) in captive conditions
(Peer reviewed; Journal article, 2019)In this study, we investigated the host choice of naïve Amphiprion ocellaris , a specialist, at two different stages of development (newly settling juveniles and post‐settlement juveniles). The fish were exposed to their ... -
Lemon sole Microstomus kitt in the northern North Sea: a multidisciplinary approach to the early life-history dynamics
(Journal article; Peer reviewed, 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 ... -
Opposite selection on behavioural types by active and passive fishing gears in a simulated guppy Poecilia reticulata fishery
(Peer reviewed; Journal article, 2015-03)This study assessed whether fishing gear was selective on behavioural traits, such as boldness and activity, and how this was related with a productivity trait, growth. Female guppies Poecilia reticulata were screened for ... -
Physical enrichment research for captive fish: Time to focus on the DETAILS
(Journal article; Peer reviewed, 2021)Growing research effort has shown that physical enrichment (PE) can improve fish welfare and research validity. However, the inclusion of PE does not always result in positive effects and conflicting findings have highlighted ... -
Thermal stratification influences maturation and timing of spawning in a local Clupea harengus population

Tracking oocyte development and the timing of skipped spawning for north-east Arctic haddock (Melanogrammus aeglefinus)
(Journal article; Peer reviewed, 2022)The present study tracked oocyte development over 9 months and noted incidences of ‘skipping’, i.e., adults terminating their upcoming reproductive cycle, in field-caught north-east Arctic (NEA) haddock (Melanogrammus ...
