Amino Acid Carriers of the Solute Carrier Families 7 (SLC7) and 38 (SLC38) Are Involved in Leucine Sensing in the Brain of Atlantic Salmon (Salmo salar)
Comesaña, Sara; Lai, Floriana; Jordal, Ann-Elise Olderbakk; Verri, Tiziano; Espe, Marit; Soengas, José L.; Rønnestad, Ivar (Journal article; Peer reviewed, 2021)Sensing of amino acids in fish brain, especially branched-chain amino acids (BCAA) like leucine, is involved in regulation of feed intake through different mechanisms. However, there is limited information regarding the ... -
Characterization of Small, Mononuclear Blood Cells from Salmon Having High Phagocytic Capacity and Ability to Differentiate into Dendritic like Cells
Haugland, Gyri Teien; Jordal, Ann-Elise Olderbakk; Wergeland, Heidrun Inger (Peer reviewed; Journal article, 2012-11-14)Phagocytes are the principal component of the innate immune system, playing a key role in the clearance of foreign particles that include potential pathogens. In vertebrates, both neutrophils and mononuclear cells like ... -
Cloning, tissue and ontogenetic expression of the taurine transporter in the flatfish Senegalese sole (Solea senegalensis)
Pinto, Wilson; Rønnestad, Ivar; Jordal, Ann-Elise Olderbakk; Gomes, Ana Silva; Dinis, Maria Teresa; Aragão, Cláudia (Peer reviewed; Journal article, 2012-04)Flatfish species seem to require dietary taurine for normal growth and development. Although dietary taurine supplementation has been recommended for flatfish, little is known about the mechanisms of taurine absorption in ... -
Daily rhythms of intestinal cholecystokinin and pancreatic proteases activity in Senegalese sole juveniles with diurnal and nocturnal feeding
Gilannejad, Neda; Rønnestad, Ivar; Lai, Floriana; Jordal, Ann-Elise Olderbakk; Gottlieb Almeida, Ana Paula; Martínez-Rodríguez, Gonzalo; Moyano, Francisco Javier; Yúfera, Manuel (Journal article; Peer reviewed, 2021)The influence of diurnal and nocturnal feeding on daily rhythms of gut levels of cholecystokinin (CCK) and the activity of two key pancreatic proteases, trypsin and chymotrypsin, were examined in juveniles of Senegalese ... -
Effect of increased rearing temperature on digestive function in cobia early juvenile
Yufera, Manuel; Nguyen, MV; Navarro-Guillén, Carmen; Moyano, Francisco Javier; Jordal, Ann-Elise Olderbakk; Espe, Marit; Conceicao, LEC; Engrola, Sofia; Le, MH; Rønnestad, Ivar (Peer reviewed; Journal article, 2019)The present study is focused to elucidate the main characteristics of the digestive function of this carnivorous fast-growing fish living at high temperatures. With this aim, we have examined the effects of an increased ... -
Elevated sea temperature combined with dietary methionine levels affect feed intake and appetite-related neuropeptide expression in the brains of juvenile cobia (Rachycentron canadum)
Nguyen, Minh; Pham, Phuong Linh; Jordal, Ann-Elise Olderbakk; Espe, Marit; Conceição, L.E.C.; Yúfera, M.; Engrola, S.; Le, M.H.; Rønnestad, Ivar (Journal article; Peer reviewed, 2023-07-04)This study aimed to determine the impact of elevated temperature combined with different levels of dietary methionine concentrations on feed intake (FI) and brain expression of selected neuropeptides and one receptor ... -
Food intake, growth, and expression of neuropeptides regulating appetite in clown anemonefish (Amphiprion ocellaris) exposed to predicted climate changes
Pham, Linh; Jordal, Ann-Elise Olderbakk; Nguyen, Minh Van; Rønnestad, Ivar (Journal article; Peer reviewed, 2021)The clown anemonefish (Amphiprion ocellaris) is a common model species in studies assessing the impact of climate changes on tropical coral fish physiology, metabolism, growth, and stress. However, the basic endocrine ... -
Metabolic rates, feed intake, appetite control, and gut transit of clownfish Amphiprion ocellaris exposed to increased temperature and limited feed availability
Pham, Phuong Linh; Nguyen, Minh Van; Jordal, Ann-Elise Olderbakk; Rønnestad, Ivar (Journal article; Peer reviewed, 2022)Episodes of elevated temperature, combined with lower feed availability, are among the predicted scenarios of climate change representing a challenge for coral reef fish. We investigated the response of clownfish (Amphiprion ... -
Nutrigenomic study of lipid metabolism in Atlantic salmon (Salmo salar L.) : the effects of dietary plant oil inclusion
Jordal, Ann-Elise Olderbakk (Doctoral thesis, 2006-09-08)The two dietary trials conducted in the present study (Papers I-III) used dietary rapeseed oil fed in a regression design and a full plant oil blend replacement for fish oil, respectively. The metabolic response of Atlantic ... -
PCB-126 spiked to polyethylene microplastic ingested by juvenile Atlantic cod (Gadus morhua) accumulates in liver and muscle tissues
Bogevik, André Sture; Ytteborg, Elisabeth; Madsen, Alexander Klevedal; Jordal, Ann-Elise Olderbakk; Karlsen, Odd Andre; Rønnestad, Ivar (Journal article; Peer reviewed, 2023)In the present study, polyethylene (PE) microplastics (150–300 μm) were added to Atlantic cod (Gadus morhua) feeds at 1 %, either in their present form (Virgin PE) or spiked with PCB-126 (Spiked PE). The feeds were given ... -
The role of dietary methionine concentrations on growth, metabolism and N-retention in cobia (Rachycentron canadum) at elevated water temperatures
Nguyen, Minh Van; Espe, Marit; Conceição, Louis E.C.; Le, Hoang Minh; Yúfera, Manuel; Engrola, Sofia A.D.; Jordal, Ann-Elise Olderbakk; Rønnestad, Ivar (Peer reviewed; Journal article, 2019-04)This study determined impacts of dietary methionine concentrations at two temperatures on growth, feeding efficiency and N‐metabolites in juvenile cobia. Methionine concentrations of the experimental diets were deficient ...
