| Abstract |
Chaetodipterus faber is a tropical marine teleost that is found over a wide area of the Northeast coast of Venezuela. Some aspects of its reproductive physiology are known. In this study, we present data on the metabolism of noradrenaline (NA), dopamine (DA) and adrenaline (A) in the brain of two populations of adult Ch. faber: (1) wild, fishes were caught in the natural habitat; or (2) captive, fishes were growth under farm culture conditions. Animals were sacrificed by decapitation, brains were dissected and five regions were separated: Hypothalamus (H), olfactory bulbs (OB), telencephalon (T), optic tectum (OT) and cerebellum (C). Levels of DA, NA, A and their metabolites: 3,4-dihydroxyphenil-acetic acid (DOPAC), homovanilic acid (HVA), 3-methoxytyramine (3-MT) and 3-methoxy-4-hydroxyphenylglycol (MHPG) were measured by HPLC-ED. The MHPG/NA and DOPAC + HVA/DA ratios were used as indexes of catecholamine activities. Data were analysed with Student's t-test and a non-parametric Kruskall-Wallis test. Significance was accepted at the 0.05 level |
