鳖病的研究比鱼病做得少,不明病因还很多。以下介绍日本大分县淡水渔业试验场近年发生的鳖病、发病特点及防治方法。 鳖病种类有:由细菌性等病原体入侵引起死亡,如细菌入侵鳖体表引起的腐皮病或赤点病;病毒引起的肿颈病;霉菌之一的真菌引起的毛霉菌病等。还有因环境因素的变化或投饵不适造成的洞穴病或肝硬化病,这种病的死亡率低,但造成鳖的外观不佳,内部脂肪组织发生变化,往往降低其商品价值。 Turtle disease research done less than fish disease, unknown cause is still a lot. The following introduces the Japanese Oita freshwater fishery test site occurred in recent years, turtle disease, incidence characteristics and prevention methods. Turtle disease types are: bacterial and other pathogens caused by the invasion of death, such as bacteria invade the turtle skin surface caused by body disease or red dot disease; virus caused by swollen neck disease; fungal mold caused by one of the mold and so on. There are also cave or cirrhosis caused by changes in environmental factors or discomfort due to feeding. The mortality rate of this disease is low, but the appearance of turtles is poor, the internal adipose tissue changes and the value of the commodity tends to be reduced.
