Gene expression analyses of immune responses in Atlantic salmon during early stages of infection by salmon louse (Lepeophtheirus salmonis) revealed bi-phasic responses coinciding with the copepod-chalimus transition
Tadiso, Tariku Markos; Krasnov, Aleksei; Skugor, Stanko; Afanasyev, Sergey; Hordvik, Ivar; Nilsen, Frank (Peer reviewed; Journal article, 2011-03-07)The salmon louse (Lepeophtheirus salmonis Krøyer), an ectoparasitic copepod with a complex life cycle causes significant losses in salmon aquaculture. Pesticide treatments against the parasite raise environmental concerns ... -
Gene expression in Atlantic salmon skin in response to infection with the parasitic copepod Lepeophtheirus salmonis, cortisol implant, and their combination
Krasnov, Aleksei; Skugor, Stanko; Todorcevic, Marijana; Glover, Kevin; Nilsen, Frank (Peer reviewed; Journal article, 2012-04-05)Background: The salmon louse is an ectoparasitic copepod that causes major economic losses in the aquaculture industry of Atlantic salmon. This host displays a high level of susceptibility to lice which can be accounted ... -
High fish density delays wound healing in Atlantic salmon (Salmo salar)
Sveen, Lene Rydal; Timmerhaus, Gerrit; Krasnov, Aleksei; Takle, Harald; Stefansson, Sigurd Olav; Handeland, Sigurd O; Ytteborg, Elisabeth (Peer reviewed; Journal article, 2018-11-15)In this study, we look closer at how high fish densities influence wound repair mechanisms in post-smolt Atlantic salmon. The fish were wounded with a 5 mm skin punch biopsy needle and stocked at two different densities, ... -
Mucosal immune and stress responses of Neoparamoeba perurans-infected Atlantic salmon (Salmo salar) treated with peracetic acid shed light on the host-parasite-oxidant interactions
Lazado, Carlo C.; Strand, David; Breiland, Mette Serine Wesmajervi; Furtado, Francisco; Timmerhaus, Gerrit; Gjessing, Mona Cecilie; Hytterød, Sigurd; Merkin, Grigory; Pedersen, Lars Flemming; Pittman, Karin Anna; Krasnov, Aleksei (Journal article; Peer reviewed, 2022)Treatment development for parasitic infestation is often limited to disease resolution as an endpoint response, and physiological and immunological consequences are not thoroughly considered. Here, we report the impact of ... -
Optimisation of trace mineral supplementation in diets for Atlantic salmon smolt with reference to holistic fish performance in terms of growth, health, welfare, and potential environmental impacts
Kokkali, Marialena; Sveen, Lene; Larsson, Thomas; Krasnov, Aleksei; Giakovakis, Alexandros; Sweetman, John; Lyons, Philip; Kousoulaki, Katerina (Journal article; Peer reviewed, 2023)The aquafeed ingredient inventory is ever changing, from marine to plant based, and recently evolving to incorporate increasing amounts of low trophic, side stream and circular economy based raw materials, each one ... -
Wound healing in post-smolt Atlantic salmon (Salmo salar L.)
Sveen, Lene Rydal; Timmerhaus, Gerrit; Krasnov, Aleksei; Takle, Harald; Handeland, Sigurd; Ytteborg, Elisabeth (Peer reviewed; Journal article, 2019-03-05)Skin biopsies (5 mm) taken from behind the dorsal fin on Atlantic salmon post-smolts were followed over a 2 month period. The healing process was dominated by hemostasis, acute inflammation, and epidermal repair the first ...
