Abstract(s)

The aim of this study was to test whether physiological changes are paralleled by changes in olfactory function during different stages of the European eel’s life-cycle. Sensitivity to diverse odorants (amino acids, bile acids, bile fluids, Na+ and Ca2+) was assessed by extra-cellular recording from the olfactory nerve of seawater or freshwater and immature or mature males. Sensitivity to amino acids did not differ markedly, whether fresh- or seawater-adapted, immature or mature. Sensitivity to bile acids and bile fluid, however, depended on the physiological status; in general, freshwater eels were more sensitive to bile acids than seawater fish.
