Most of the diadromous fish of the area have reduced in distribution and abundance because the starting of the 20th century. they're now threatened, and demanding conservation concerns come up. The factors of those traits fluctuate between species and basins yet neighborhood human influence (damming, toxins, fisheries) and worldwide swap (climate) are suspected to be accountable for those problems. This ebook includes chosen papers from a world symposium organised through the Diadfish community held in Bordeaux (France) in 2005. Readers will locate up to date info at the ecology, ecotoxicology and body structure of a number of diadromous species (Atlantic salmon, shads, lampreys, eels) and this complete team in Europe. major affects also are documented and analysed in case reports, and ideas or remediation activities are presented.

Seasonal and circadian variations in the CA amount have been first studied using the FIF method (Popek, 1983) or radioimmunoenzymatic labeling (Le Bras, 1984). These authors reported that the CA content was generally higher during the light phase compared to the dark phase (Popek, 1983; Le Bras, 1984). , 1984). Catecholamine content in eel brain (HPLC assay) HPLC measurements of DA and DOPAC in the eel indicated variations at different stages of the biological cycle: DA and DOPAC contents in the olfactory bulbs were significantly higher in silver eels (migratory stage) compared to yellow eels (growth stage).

Our study demonstrates for the first time that DOPAC is the major metabolite of DA in all brain parts of the eel. Large concentrations of DOPAC (Fig. 4 ng/g tissue). In the other brain areas, DOPAC contents were low with almost undetectable levels in the cerebellum (\10 ng/g tissue). 5 ng/g tissue, data not shown). The DOPAC/DA ratio (Fig. , 1994).
