The results showed that both dialkyl quaternary ammonium salts can restrain the growth of aeromonas hydrophila and flexibacter colnmnaris,and the short one was more effective than the long one while comparing their inhibiting effects to aquatic pathogenic bacteria.

Result showed that dialkyl quaternary ammonium salts inhibited the growth of Aeromonas hydrophila and Flexibacter colnmnaris,and the short alkyl group is more effective than the long one.

Objective:The study focused on the colonial distribution of Flexibacter columnaris,Escherichia coli and Vibrio anguillarum on the surface of different carriers in fishpond.

According to the biological features,Physiological--biochemical analysis and pathogenicity detection of the SC--3 and SC--6, the two strains wereidentified to be Flexibacter columnaris, the pathogen of the rotted gill disease of mandarin fish (Sinipercachuatisi).
