引起观赏鱼疾病的种类有哪些

  • 来源: 日期:2019-05-14 发布人:澳门金莎免费娱乐 阅读数:
  观赏鱼的疾病种类很多,一般将其分为两大类:一类主要由有生命的动物、植物或微生物引起,如由寄生虫、真菌、单细胞藻类、细菌及病毒等引起的疾病,成为生物性疾病。
  There are many kinds of diseases in ornamental fish, which are generally divided into two categories: one is mainly caused by living animals, plants or microorganisms, such as parasites, fungi, single-cell algae, bacteria and viruses, which become biological diseases.
  其中由寄生虫引起的鱼病称为观赏鱼寄生虫性疾病,包括单细胞原虫,其特点一般是发病和传播较慢,发病率和死亡率较低,防治也较容易。由真菌、细菌和病毒等引起的疾病,大多发病急、传播快、发病率和死亡率都比较高,有较强的传染性,故称之为观赏鱼传染性疾病,此类鱼病不易防治。寄生虫性疾病和传染性疾病统称为侵袭性鱼病或生物性鱼病。
  Among them, fish diseases caused by parasites are called ornamental fish parasitic diseases, including single-cell protozoa, which are characterized by slow incidence and transmission, low morbidity and mortality, and easy prevention and control. Most of the diseases caused by fungi, bacteria and viruses have high incidence, rapid transmission, high morbidity and mortality, so they are called ornamental fish infectious diseases, which are not easy to control. Parasitic and infectious diseases are commonly referred to as invasive fish diseases or biological fish diseases.
  观赏鱼疾病第二类---另一类疾病称之为非生物性鱼病或生理性疾病,主要是由水体环境中的机械、物理、化学等非生物因素引起,或因鱼体生理机能失调所引起机体的代谢障碍或机能紊乱而导致。
  The second category of ornamental fish diseases is called abiotic fish diseases or physiological diseases, which are mainly caused by mechanical, physical, chemical and other abiotic factors in the water environment, or by metabolic disorders or functional disorders caused by physiological dysfunction of the fish body.
  此类鱼病的种类很多,病因复杂,危害较大,涉及面也较广,如因缺氧而引起的“浮头”和“泛池”、工业或生活污水引起的鱼类中毒等。但无论是哪一类鱼病,只要加强管理,做好生物安全和综合预防工作,都可以完全避免其发生,若按疾病的临床症状和病程的长短,观赏鱼疾病又可分为急性型、慢性型和潜伏型三种类型。
  There are many kinds of fish diseases, such as floating head and pan-pond caused by hypoxia, fish poisoning caused by industrial or domestic sewage, etc. However, no matter what kind of fish diseases, as long as we strengthen management and do a good job in biosafety and comprehensive prevention, they can be completely avoided. According to the clinical symptoms and duration of the disease, ornamental fish diseases can be divided into three types: acute, chronic and latent.

  1.急性型疾病
  1. Acute diseases
  急性型疾病是指观赏鱼在正常生活条件下,很快由生理性行为转化为病理性行为,其特点是发病急、死亡率高,病程迅速,有数天到1~2周,如由黏球菌引起的白头白嘴病,发病1~3天后即可使成千上万只鱼苗死亡;2.局部性疾病局部性疾病是指病理变化主要仅限于身体的某一部分,如皮肤病、鳃病、肠道病、眼病、肌肉病、肝病、骨病、胆囊病、鳔病等;全身性疾病是指此类疾病影响到整个机体,如泛塘、中毒、饥饿、营养不良、败血症等。
  Acute diseases refer to ornamental fish's rapid transformation from physiological behavior to pathological behavior under normal living conditions. They are characterized by acute onset, high mortality rate, rapid course of disease, from several days to 1-2 weeks. For example, white-headed and white-mouthed disease caused by myxococcus, thousands of fry can die within 1-3 days after onset. 2. Local diseases refer to pathological changes that are mainly confined to the body. Some parts of the body, such as skin disease, gill disease, intestinal disease, eye disease, muscle disease, liver disease, bone disease, gallbladder disease, bladder disease and so on; systemic disease refers to such diseases affecting the whole body, such as pantang, poisoning, hunger, malnutrition, septicemia, etc.

  Chronic diseases have a slightly longer course, with no death peak for 2 weeks to several months, such as chronic gill mildew; latent diseases refer to the presence of pathogens in ornamental fish. Normally, the body surface does not show clinical symptoms, but when changes in the surrounding environment lead to a decline in the resistance of fish, the pathogens in the body begin to multiply in large quantities, leading to the occurrence of diseases, thus strengthening. Feeding and management to improve the disease resistance of fish is the most effective way to prevent and treat this kind of disease. Ornamental fish diseases can be classified into local diseases and systemic diseases if they are classified according to the location of disease invasion.
