Plasma catecholamines and accumulation of adrenaline in the atrial cardiac tissue of aquacultured Atlantic salmon ( Salmo salar) during stress
The effects of stress on plasma catecholamines (CA) and capacity for tissue accumulation of CA were studied in cardiac and skeletal muscle of cultured Atlantic salmon ( Salmo salar L.). Adrenaline (A) and noradrenaline (NA) were quantified by high performance liquid chromatography. Plasma A and NA l...
