摘　　要：作者对鲫腐皮病的病因及病原菌进行了初步研究。结果表明：在水温为１８．１～３１．０℃时，病程为４８～１２０ｈ；随着水温的升高感染力加强，二者呈显著正相关，ｒ＝０．９５８（ｎ＝５）；经对病原菌进行分离培养，生理生化反应测定，初步认为是点状产气单胞菌点状亚种（ＡｅｒｏｍｏｎａｓｐｕｎｃｔａｔａＳｕｂ．ｐｕｎｃｔａｔａ）。The prelimary studies on the cause and pathogenic bacteria of the“rot-ten─skin”disease of crucian carp had been carried out. The results showed that the diseased course in 48─120 h under 18.1─31.O℃of water temperature,The correlationship between water temperature and infectiuity was signifieantly positive(r=0.958,n=5).The isolated calture and determination of reaction in physiolo-gy and biochemistry showed that the pathogenic bacteria was Aeromonas punctats sub.punctata.
