The physiological characteristics of a Vibrio alginolyticus Bacteriophage was studied and the Bacteriophage was isolated from market of aquatic products in Zhanjiang. The results showed that the diameter of Bacteriophage plaque was l-1.5mm (12h). Lytic activity of Bacteriophage lost within 30 min when Bacteriophage exposed to UV light (20W, 30cm). Bacteriophage were UV-sensitive. They had strong lytic activity at pH 8 -11, and the optimum pH value was 11. The lytic cycle of them was 65 min. They were sensitive as the ambient temperature was more than 65℃. They were tolerated with ether and chloroform. They were sensitive to antiviral drugs acyclovir. Routine test dilution(RTD) was 106. Optimal multiplicity of infection was 10.%对从湛江市水产品批发市场分离得到一株溶藻弧菌噬菌体的生理特性进行测定,结果表明:该株噬菌体噬菌斑12h直径为1～1.5mm,对紫外线敏感,暴露在紫外灯(20W,30 cm)下30 min可丧失全部裂解活性；在pH8-11范围内裂解活性较强,最适pH值为11,裂解周期为65 min,对65℃以上的高温敏感,对乙醚和氯仿有较好的耐受性,对抗病毒药物阿昔洛韦敏感,最大常规稀释度为106 CFU/mL,最佳感染复数为10.
