Abstract: | Plasma norepinephrine and epinephrine from cannulated trout were measured by high pressure liquid chromatography with electrochemical detection. The catecholamines were extracted with acid-washed alumina using a microfilter assembly which permitted analysis of small volumes of plasma. Mean (± S.D.) values for plasma norepinephrine and epinephrine were 1.83 (0.97) pmol ml?1 and 8.95 (4.94) pmol ml?1, respectively. These values are compared with catecholamine levels from other vertebrate species. |
