Tissue accumulation of polystyrene microplastics causes oxidative stress, hepatopancreatic injury and metabolome alterations in Litopenaeus vannamei
(Peer reviewed; Journal article, 2023)Microplastics (MPs) pose one of the major environmental threats to marine organisms and ecosystems on a global scale. Although many marine crustaceans are highly susceptible to MPs pollution, the toxicological effects and ... -
To Be, or Not to Be: That Is the Hamletic Question of Cryptic Evolution in the Eastern Atlantic and Mediterranean Raja miraletus Species Complex
(Peer reviewed; Journal article, 2023)Despite a high species diversity, skates (Rajiformes) exhibit remarkably conservative morphology and ecology. Limited trait variations occur within and between species, and cryptic species have been reported among sister ... -

Tolerance and dose-response assessment of subchronic dietary ethoxyquin exposure in Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2019)Ethoxyquin (EQ; 6-Ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline) has been used as an antioxidant in feed components for pets, livestock and aquaculture. However, possible risks of EQ used in aquafeed for fish health have not ... -
Tolerance of Atlantic cod (Gadus morhua L.) larvae to acute ammonia exposure.
(Peer reviewed; Journal article, 2020)Tolerance for acute ammonia exposure, defined to exist between NOEC (no observed effect concentration) and LOEC (lowest observed effect concentration), was validated in seven exposure experiments with Atlantic cod larvae ... -
Torsk, hyse og havforskarar
(Journal article, 1980)Trålfisket etter torsk og hyse i Barentshavet har vore uvanleg rikt hittil i år, og dette har overraska mange på bakgrunn av dei låge fangstkvotane for 1980. Har havforskarane tatt feil i vurderingane sine av bestanden? I ... -

Torskeoppdrett i nedsenkede merder?
(Journal article, 2011-05)På grunn av torskens forkjærlighet for lavere sommertemperaturer og høyere vintertemperaturer enn det man ofte finner i de øverste lagene i vannsøylen, har både kommersielle aktører og forskere forsøkt med oppdrett av ... -
Total Catch of a Red-Listed Marine Species Is an Order of Magnitude Higher than Official Data
(Journal article; Peer reviewed, 2012-02-17)Accurate information on total catch and effort is essential for successful fisheries management. Officially reported landings, however, may be underestimates of total catch in many fisheries. We investigated the fishery ... -
Toward a coordinated global observing system for marine macrophytes
(Journal article; Peer reviewed, 2019)In coastal waters around the world, the dominant primary producers are benthic macrophytes, including seagrasses and macroalgae, that provide habitat structure and food for diverse and abundant biological communities and ... -
Toward a Global Ocean Ecosystem Mid-trophic Automatic Acoustic Sampler (MAAS)
(Journal article; Peer reviewed, 2009-05-26)Despite their huge biomass and pivotal role, the mid-trophic levels of marine ecosystems are not generally subject to systematic monitoring. Data from such monitoring is crucial for parameterizing, validating, and constraining ... -
Toward a global reference database of COI barcodes for marine zooplankton.
(Peer reviewed; Journal article, 2021)Characterization of species diversity of zooplankton is key to understanding, assessing, and predicting the function and future of pelagic ecosystems throughout the global ocean. The marine zooplankton assemblage, including ... -
Toward a model-based prediction system for salmon lice infestation pressure
(Journal article; Peer reviewed, 2016-09-08)High salmon lice density is a threat to wild and farmed salmonid fish in Norway. To assess and identify areas for high salmon lice infestation pressure, continuous monitoring is necessary. The national Norwegian salmon ... -
Towards an Autonomous Pelagic Observatory: Experiences from Monitoring Fish Communities around Drifting FADs
(Journal article; Peer reviewed, 2019)This work presents a methodological synthesis for the in situ monitoring of fish aggregating devices (FADs) using a combination of optical, echosounder and SCUBA observations conducted in the vicinity of drifting FADs. The ... -
Towards cod without spawning: artificial continuous light in submerged sea-cages maintains growth and delays sexual maturation for farmed Atlantic cod Gadus morhua
(Journal article; Peer reviewed, 2013-06-04)Sexual maturation and spawning in sea-cages is a major production and environmental challenge for the Atlantic cod farming industry. Altered photoperiod has arrested sexual maturation in cod kept in indoor or covered ... -
Towards direct evidence of the effects of salmon lice (Lepeophtheirus salmonis Kr?yer) on sea trout (Salmo trutta L.) in their natural habitat: proof of concept for a new combination of methods
(Journal article; Peer reviewed, 2018)Studies addressing the impact of salmon lice (Lepeophtheirus salmonis Krøyer) on sea trout in their natural habitat are scarce and mostly limited to prophylaxis-based experiments. The main drawbacks with this approach are ... -
