...Joseph D. Norman; Moira M. Ferguson; Roy G. Danzmann High-throughput RNA sequencing was used to compare expression profiles in two Arctic charr ( Salvelinus alpinus ) families post-seawater exposure to identify genes and biological processes involved in hypo-osmoregulation and regulation...

...Even Hjalmar Jørgensen; Mads Martinsen; Vidar Strøm; Kristin Elisa Ruud Hansen; Chandra Sekhar Ravuri; Ningping Gong; Malcolm Jobling SUMMARY The life strategy of the anadromous Arctic charr ( Salvelinus alpinus ) includes several months of voluntary fasting during overwintering in freshwater...

...Erik Höglund; Paul H. M. Balm; Svante Winberg SUMMARY In salmonid fish, a darker skin colour has been suggested to signal social subordination. Substratum colour is another factor affecting skin pigmentation in fish; in the present experiment, juvenile Arctic charr ( Salvelinus alpinus ) were...

...Tiina Lecklin; Mikko Nikinmaa ABSTRACT In the present study, we have examined the adrenergic responses of Arctic charr ( Salvelinus alpinus ) erythrocytes acclimated to different temperatures (2, 8 and 14 °C) during different seasons. We measured the changes in cellular water and ion contents after...

... was resuspended in 10 ml of Tris–HCl buffer (pH 7.4) containing 10 µmol l −1 pargyline, 4 mmol l −1 CaCl 2 and 0.1 % ascorbic acid. Suspensions from 6–12 brains were mixed and used immediately in the binding assay. The fish (weighing 30–60 g) were 2-year-old juvenile Arctic charr ( Salvelinus alpinus L...

... 7:00 and 19:00h. The fish (weighing 45.7±5.8g, mean ± S.D., N =78) were 2-year-old juvenile offspring of Arctic charr ( Salvelinus alpinus L.) caught in lake Hornavan, Lapland, Sweden. They were kept indoors at the Department of Zoophysiology, in a holding tank continuously supplied...

...Svante Winberg; Göran E. Nilsson; Berry M. Spruijt; Urban Höglund ABSTRACT Using a computerized video-image analysis system, spontaneous locomotor activity was measured in dominant and subordinate individuals of Arctic charr ( Salvelinus alpinus ) and in individuals treated with inhibitors...

...Svante Winberg; Göran E. Nilsson; K. Håkan Olsén ABSTRACT The effects of stress and starvation on brain levels of serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) were studied in Arctic charr (Salvelinus alpinus) . Three experimental protocols were used to elucidate (1) the effect of stress...
