The antibacterial effect amino acid-copper(Ⅱ) surfactant on fish pathogens was studied. Fish pathogens of Edwardsiella tarda, Vibrio anguillarum, Aeromonas hydrophila and Streptococcus sp. were selected, cultured in nutrient agar and adjusted at 2 × 10 5∼106 CFU/㎖ in phosphate buffer saline before the addtion of amino acid-copper(Ⅱ) surfactant with different concentrations. All tested pathogens died within 1 hour with 1 ppm of amino acid-copper(Ⅱ) surfactant. In comparison with formalin and ET, amino acid-copper(Ⅱ) surfactnat was more effective in antibacterial capacity.
