The efficiency of chitosan against Vibrio spp. isolated from black tiger shrimp was studied. The minimum bactericidal concentration (MBC) of chitosan was 1000 ppm. The chitosan could be used to control the growth of bacteria at both high and low organic matters. The effects of the inoculation size on the activities of chitosan at 1000 ppm were 102-108 c.f.u./ml. The MBCs of chitosan tested with 47 isolated Vibrio spp. ranged from 1000-10 000 ppm.
