Evolutionary expression differences of creatine synthesis-related genes: Implications for skeletal muscle metabolism in fish
Borchel, Andreas; Verleih, Marieke; Kühn, Carsten; Rebl, Alexander; Goldammer, Tom (Peer reviewed; Journal article, 2019)The creatine/phosphocreatine system is the principal energy buffer in mammals, but is scarcely documented in fish. We measured the gene expression of major enzymes of this system, glycine amidinotransferase (GATM), ... -
Identification and Description of the Key Molecular Components of the Egg Strings of the Salmon Louse (Lepeophtheirus salmonis)
Borchel, Andreas; Kongshaug, Heidi; Nilsen, Frank (Peer reviewed; Journal article, 2019-12-03)The salmon louse Lepeophtheirus salmonis is a parasite of Atlantic salmon and other salmonids. Every year, it causes high costs for the Norwegian aquaculture industry. While the morphology of the female genital tract has ... -
Mining Lepeophtheirus salmonis RNA-Seq data for qPCR reference genes and their application in Caligus elongatus
Borchel, Andreas; Eichner, Christiane; Øvergård, Aina-Cathrine (Journal article; Peer reviewed, 2023)Lepeophtheirus salmonis and Caligus elongatus are two parasitic copepod species posing a significant threat to salmonid aquaculture. Consequently, several gene expression studies are executed each year to gain new knowledge ... -
Salmon louse labial gland enzymes: implications for host settlement and immune modulation
Midtbø, Helena Marie Doherty; Eichner, Christiane; Hamre, Lars Are; Dondrup, Michael; Flesland, Linn; Tysseland, Kristoffer Helland; Kongshaug, Heidi; Borchel, Andreas; Nilsen, Frank; Øvergård, Aina-Cathrine (Journal article; Peer reviewed, 2024)Salmon louse (Lepeophtheirus salmonis) is a skin- and blood-feeding ectoparasite, infesting salmonids. While feeding, labial gland proteins from the salmon louse may be deposited on the Atlantic salmon (Salmo salar) skin. ... -
Sex differences in the early life stages of the salmon louse Lepeophtheirus salmonis (Copepoda: Caligidae)
Borchel, Andreas; Komisarczuk, Anna Zofia; Nilsen, Frank (Journal article; Peer reviewed, 2022)Salmon lice are ectoparasites on salmonids and feed on blood, mucus, and skin from their hosts. This causes high annual costs for treatment and control for the aquaculture industry. Salmon lice have a life cycle consisting ... -
The synergistic interaction of thermal stress coupled with overstocking strongly modulates the transcriptomic activity and immune capacity of rainbow trout (Oncorhynchus mykiss)
Rebl, Alexander; Korytář, Tomáš; Borchel, Andreas; Bochert, Ralf; Strzelczyk, Joanna Ewa; Goldammer, Tom; Verleih, Marieke (Journal article; Peer reviewed, 2020)The objective of the present study is to identify and evaluate informative indicators for the welfare of rainbow trout exposed to (A) a water temperature of 27 °C and (B) a stocking density of 100 kg/m3 combined with a ... -
Transcriptomic and targeted immune transcript analyses confirm localized skin immune responses in Atlantic salmon towards the salmon louse
Øvergård, Aina-Cathrine; Eichner, Christiane; Nuñez-Ortiz, Noelia; Kongshaug, Heidi; Borchel, Andreas; Dalvin, Sussie Trine (Journal article; Peer reviewed, 2023)Atlantic salmon (Salmo salar) are highly susceptible to infestations with the ectoparasite Lepeophtheirus salmonis, the salmon louse. Infestations elicit an immune response in the fish, but the response does not lead to ... -
The transcriptomic response of adult salmon lice (Lepeophtheirus salmonis) to reduced salinity
Borchel, Andreas; Heggland, Erna Irene; Nilsen, Frank (Journal article; Peer reviewed, 2021)Salmon lice (Lepeophtheirus salmonis) are marine parasitic copepods living on salmonids and are challenging for salmon aquaculture. One of several treatment methods is the application of freshwater to the fish which can ... -
Without a pinch of salt: effect of low salinity on eggs and nauplii of the salmon louse (Lepeophtheirus salmonis)
Borchel, Andreas; Heggland, Erna Irene; Nilsen, Frank (Journal article; Peer reviewed, 2023)The salmon louse is an economically important parasite on Atlantic salmon and poses a major threat to aquaculture. Several treatment methods have lost their effect due to resistance development in the lice. A rather new ...
