Free amino acids content in the skin mucus of yellow and silver eel, Anguilla anguilla
International audience Free amino acid contents in skin mucus extracts were analysed in sexually undinerentiated yellow eels, female yellow eels and male and female silver eels trapped at the same time from the same freshwater location. Total free amino acid contents in skin mucus were similar in th...

Total free amino acid contents in skin mucus were similar in the three groups of sexually differentiated eels (16.2–18.2μM/g dry weight). In sexually undinerentiated yellow eels, total content was higher (39.6μM/g dry weight). Free amino acid composition of skin mucus from male and female silver eels were similar.
