... migration success. European populations of brown trout ( Salmo trutta ) exhibit partial migration, whereby a portion of the population smoltifies and migrates to the ocean, and the rest remain in their natal stream. This distinct, natural dichotomy of life-history strategies provides an excellent...

... well as repeatability of body mass, in young brown trout ( Salmo trutta L.) fed a moderately restricted diet (0.5–0.7% fish mass day –1 ). Metabolism was estimated from measurements of oxygen consumption rate ( ) and repeatability was evaluated four times across a 15-week period. Individual body mass...

... stress in wild-type European brown trout, Salmo trutta . A positive correlation between post-stress cortisol levels and CSI was observed, supporting an association between enhanced cortisol response and myocardial remodeling. In conclusion, post-stress cortisol production correlates with myocardial...

...N. Day; P. J. Butler SUMMARY Adult brown trout ( Salmo trutta ) were acclimatised to and maintained at seasonal temperatures (5°C in winter; 15°C in summer)and acclimated to reversed seasonal temperatures (15°C in winter; 5°C in summer) while exposed to the natural (i.e. seasonally variable...

...Christian Nielsen; Kim Aarestrup; Ulrik Nørum; Steffen S. Madsen SUMMARY The relationship between premigratory gill Na + /K + -ATPase activity, determined at two dates during spring, and future migratory behaviour was investigated using non-lethal gill biopsies and PIT-tagging in wild brown trout...

...Christian K. Tipsmark; Steffen S. Madsen SUMMARY In teleost fish, successful osmoregulation involves controlled ion transport mechanisms in kidney and gill epithelia. In this study, the effect of nitric oxide (NO) on Na + /K + -ATPase was investigated in vitro in these two tissues in brown trout...

...P. J. BUTLER; N. DAY; K. NAMBA Adult brown trout were acclimated for 2–4 weeks to artificial, soft water (Ca 2+ 25μmoll −1 ) at neutral pH and at summer (15°C) or winter (5°C) temperatures. During this period they swam against a current of approximately 0.25 ms −1 . They were then exposed to...
