The heterotrophic bacterial microflora of European eel reared in freshwater and its surround-ing aqueous environment is reported. Quality of eel culture water is also discussed with respect to its physicochemical and bacteriological characteristics. The presence of bacterial species pathogenic for eel and its serological classification was investigated in fishery water and eels. Overall 675 isolates from fishery water and healthy or diseased were eel identified at genus level. Pseudo-monas was the most frequently encountered genus. Moraxella sp. and Acinetobacter sp. were abundant in fishery water, and Aeromonas sp. in elver and internal organs of silver eel. Plesiomonas sp., Escherichia sp., Enterobacter sp., Serratia sp., Citrobacter sp., and Streptococcus sp. were minority genera that were only recovered from eel. The species Aeromonas hydrophila, A. sobria, and Alteromonas putrefaciens were mostly isolated from diseased eel whereas other potential fish pathogens such as P. fluorescens, V. anguillarum, and Plesiomonas shigelloides were generally observed in fishery water or healthy eel. Following the typing scheme of Guinée and Jensen, most of the isolates of A. hydrophila from diseased European eels, as well as the strain A. hydrophila Y-62 pathogenic for Japanese eel, belonged to O19 serogroup. A relationship between origin and serogroup for A. sobria was not observed. None Vibrio anguillarum isolates agglutinated with O1 and O2 antisera of Sorensen and Larsen.
