The Effect of Nutrient Availability and Light Conditions on the Growth and Intracellular Nitrogen Components of Land-Based Cultivated Saccharina latissima (Phaeophyta)
(Peer reviewed; Journal article, 2020)With the increasing interest and activities regarding seaweed cultivation in Europe, it is becoming crucial to utilize the opportunities that lies within environmental resources, such as light and nutrients, to produce ... -
Effect of Siderophore on Iron Availability in a Diatom and a Dinoflagellate Species: Contrasting Response in Associated Bacteria
(Journal article; Peer reviewed, 2018)Organic ligands play a key role controlling trace metal bioavailability in the world's oceans, yet the species-specific requirements determining whether certain iron forms can be metabolized largely remain unclear. ... -
Effects of temperature, salinity and diet on embryonic and early larval development in Littorina littorea (Gastropoda: Littorinimorpha)
(Peer reviewed; Journal article, 2023)Introduction: The common periwinkle Littorina littorea is a delicacy in southern Europe. Enabling aquaculture production would be measure to avoid future over-harvesting and ensure a constant market supply. Methods: ... -
The essentials of marine biotechnology
(Peer reviewed; Journal article, 2021)Coastal countries have traditionally relied on the existing marine resources (e.g., fishing, food, transport, recreation, and tourism) as well as tried to support new economic endeavors (ocean energy, desalination for water ... -
Estimation of fish catch potential using assimilation of synthetic measurements with an individual-based model
(Journal article; Peer reviewed, 2023)A large fraction of costs in wild fisheries are fuel related, and while much of the costs are related to gear used and stock targeted, search for fishing grounds also contributes to fuel costs. Lack of knowledge on the ... -
Extreme Levels of Ocean Acidification Restructure the Plankton Community and Biogeochemistry of a Temperate Coastal Ecosystem: A Mesocosm Study
(Peer reviewed; Journal article, 2021)The oceans’ uptake of anthropogenic carbon dioxide (CO2) decreases seawater pH and alters the inorganic carbon speciation – summarized in the term ocean acidification (OA). Already today, coastal regions experience episodic ... -
Feeding and water temperature modulate the potential activity of gut microbiota in greater amberjack juveniles (Seriola dumerili)
(Peer reviewed; Journal article, 2023)Gut microbial communities are highly dynamic and respond to factors such as diet and host metabolism. However, there is limited knowledge on changes in gut microbiota during the daily cycle. To investigate how interactions ... -
"Hanging gardens" - comparing fauna communities in kelp farms and wild kelp forests
(Peer reviewed; Journal article, 2023)A growing need for food is causing increased interest for seaweed farming globally. This requires knowledge of the industry’s effects on the marine environment. We therefore aimed to explore the communities hosted by a ... -
How can mariculture better help feed humanity?
(Peer reviewed; Journal article, 2015)The primary production of the marine and the terrestrial domains are similar, ~49 and 56 Gt C year−1, respectively (Field et al., 1998), and the marine primary production must likely be more readily available for grazing ... -
Incorporation of feed and fecal waste from salmon aquaculture in great scallops (Pecten Maximus) co-fed by different algal concentrations
(Journal article; Peer reviewed, 2019)Juvenile scallops of Pecten maxiumus were studied to see the capability to clear out and incorporate salmon feed and feces (30 µg L-1). Algae were also given, in a low and high concentration in addition to feed and faeces, ... -
Influence of nitrogen limitation on lipid accumulation and EPA and DHA content in four marine microalgae for possible use in aquafeed
(Journal article; Peer reviewed, 2019)Microalgae are regarded as a promising alternative that can replace fishmeal and fish oil in aquaculture. Under N-limitation, many microalgae species change their carbon storage patterns in favor of neutral lipids (NLs) ... -
Light regulation of LHCX genes in the benthic diatom Seminavis robusta
(Peer reviewed; Journal article, 2020)Intertidal benthic diatoms experience a highly variable light regime, which especially challenges these organisms to cope with excess light energy during low tide. Non-photochemical quenching of chlorophyll fluorescence ... -
Modeling the influence of eutrophication and redox conditions on mercury cycling at the sediment-water interface in the Berre Lagoon
(Journal article; Peer reviewed, 2018)This study presents a specifically designed Mercury module in a coupled benthic-pelagic reactive-transport model - Bottom RedOx Model (BROM) that allows to study mercury (Hg) biogeochemistry under different conditions. ... -
A New Network for the Advancement of Marine Biotechnology in Europe and Beyond
(Peer reviewed; Journal article, 2020)Marine organisms produce a vast diversity of metabolites with biological activities useful for humans, e.g., cytotoxic, antioxidant, anti-microbial, insecticidal, herbicidal, anticancer, pro-osteogenic and pro-regenerative, ... -
Occurrence and Habitat Characteristics of Aurelia sp. Polyps in a High-Latitude Fjord
(Peer reviewed; Journal article, 2021)Causes and consequences of jellyfish bloom formation are subject to controversial discussions worldwide. While medusae have been studied to a broader extent, the knowledge on polyp stages of scyphozoans is limited thus ... -
A Persistent Sea-Going Platform for Robotic Fish Telemetry Using a Wave-Propelled USV: Technical Solution and Proof-of-Concept
(Peer reviewed; Journal article, 2022)Over the last few decades, acoustic fish telemetry has developed into a viable approach for remote monitoring of fish behaviour in the marine environment. Simultaneously, unmanned surface and underwater vehicles have found ... -
Phenylalanine Hydroxylase RNAi Knockdown Negatively Affects Larval Development, Molting and Swimming Performance of Salmon Lice
(Peer reviewed; Journal article, 2020)Phenylalanine hydroxylase (PAH) is a crucial enzyme involved in tyrosine biosynthesis, having roles in neurological and physiological processes. The purpose of PAH has received little attention in crustaceans despite ... -
