What does the element that causes piscine disease to happen have

The person is an element

? In raising a process, often should change water to aquaria or aquatic animals box, add water, cent box, clean and scoop up a fish, because the operation is undeserved,can make the fish skips to go up to the ground sometimes, or appliance meets piscine system, cause fin craze, scale falls off. Such, the bacteria is invaded very easily from cut, make piscine sicken. For example, mildew of sodden branchial disease, water is affected through this way. Additional, often blow those who feed adherent alga to view and admire a fish, kiss an easy also infection.
Fish for vivid bait from inside nature, collect aquatic and buy a fish, cast when feeding, because disinfection, clean work is not complete, the likelihood takes person pathogen. Additional, the tool that is used at ill fish is used at having ill fish again without disinfection, buy merman newly perhaps to put original school to wait without keeping apart observation, can repeat infection or alternate infection. For example, such infection come on disease of small melon bug, sodden branchial disease.
?
Viewing and admire a fish basically is to rely on to be cast artificially hello raise. If cast,feed undeserved, or be hungry or full reach cast for a long time feed makings doing bait, bait expects breed is onefold, nutrient composition is insufficient, makings of bait of devoid animal sex and reasonable protein, vitamin, microelement, view and admire a fish to be able to lack nutrition so, cause a constitution feeble, affect sicken easily. Of course, cast bait overmuch, easy cause water quality corruption, stimulative bacterium multiplies. Additional, cast fed bait makings metamorphism, corruption, can bring about directly view and admire a fish to fall ill.
?
View and admire a fish to change property to have certain accommodation to the manage of water system. If the fish holds inside unit water system,measure too much, easy bring about existent zoology environment very abominable, add change water not in time, fecal, secretion of the fish is overmuch, grow in quantity of nitrogen of carbon dioxide, ammonia, microbial breed, phytolankton of blue green alga grows overmuch, can make water quality exasperate, dissolve oxygen quantity is reduced, make the fish comes on. The Shui Wenchao when changing water crosses the upper limit of accommodation or floor level, and water is warm inside short time changeful, or lukewarm on the low side of long period water, can make the fish comes on.

Oneself element

? The stand or fall of element of piscine body self is to resist the main factor of bacterium of ab extra cause of disease. Healthy fish prevents the happening of partial fish disease effectively. The physiology element of oneself element and piscine body and fish immunity ability are concerned.
? (1)
Physiology element fish reachs counteractive ability to wait along with the age, healthy state, nutrition to the reaction ability of outside disease change and have different. For example wheel bug disease is the seedling is planted the epidemic disease with common level, and the growth as piscine body age, although have wheel bug parasitism, also won’t cause the happening of the disease commonly. Scale, skin and mucus are the important protective screen that piscine body resists helminth is invaded. Healthy fish or body watch do not get scathing fish, pathogen cannot be entered, wait to won’t happen like mildew of the disease that print, water.
? (2)
Immune ability? Cause of disease is microbial after taking merman put oneself in another’s position, constant by fish gobble up cellular place, attract leucocyte to arrive get hurt place, gobble up cause of disease together microbial, show inflammation reaction. If gobble up cell and leucocyte gobble up ability to hold back the growth with microbial cause of disease hard when progenitive speed, local pathological changes will expand subsequently, exceed piscine system bear force and cause piscine death.

Biology element

(1)Pathogen? The pathogen that views and admire a fish has fungus, bacterium, virus, protozoan to wait. These pathogen are the culprit that the influence views and admire piscine health. In piscine body, pathogen amount is more, the symptom of piscine disease is more apparent, serious when can bring about fish to die in great quantities directly.
?
The size that piscine ill pathogen infects force and pathogen are inside host body resident, multiply and the amount from the eduction inside host body have affinity. Water system condition is exasperate, be helpful for parasitism biology growing progenitive environment, its infect ability stronger, apparent also to viewing and admire the action of the fish that cause disease. If use,ecological method restrains pathogen to vigor will reduce or eliminate pathogen, if use calx disinfection regularly, or put in nitrify bacterium to increase dissolve oxygen, purify the ecological method such as water quality to handle water environment, go against parasitism biologic to grow progenitive, reduce apparently to viewing and admire the action of the fish that cause disease, piscine disease produces an opportunity to be reduced. Accordingly, cut off pathogen to enter the way that breeds water system, the contagion of the pathogen according to viewing and admire fish force and the character of the force that cause disease, ground of have a definite object in view undertakes zoology prevention and cure, medicaments prevention and cure and immunity prevent and cure, pathogen control is not endangering the degree that views and admire fish the following, reduce those who view and admire fish disease to happen.
? (2)
Alga a few alga, alga of alga of the armour that be like egg, a network of rivers, have immediate effect to viewing and admire a fish. Alga of a network of rivers often is twined view and admire piscine juvenile and cause death; And alga of armour of acerbity egg of be addicted to can be caused view and admire piscine happening to make powdery disease.
? (3)
Enemy kill? View and admire a fish enemy kill basically liver mosses of rat, snake, bird, frog, feral fish, aquatic insect, bloodsucker, green mud waits. These natural enemy, devour directly on one hand view and admire a fish and cause a loss, on the other hand they already were become certain the host that views and admire piscine helminth or transmission way. For example, gull bird can spread disease of answer mouth fluke other view and admire a fish.

Environmental element

? The environmental factor that affects fish health basically has water lukewarm, water quality, base is quality etc.
? (1)
Water is warm viewing and admire fish is cold-blooded animal, temperature follows outside ambient especially the water of water system is warm change and change. When water when the lukewarm happening that change quickly, because airframe gets used to ability not strong and change of hair unripe pathology and even death. View and admire difference in temperature of the requirement when the fish is changing water for example under3The seedling is planted the difference in temperature of level under2, can pass because of difference in temperature otherwise big and bring about view and admire piscine cold, even large quantities of death.
? (2)
The stand or fall of water quality water quality matters to those who view and admire a fish to grow directly. Content of nitrogen of oxygen of the acid-base value that affects water to pledge metabolic element has water system, dissolve, organic oxygen demand, diaphaneity, ammonia. These elements, its index is inside appropriate limits when, view and admire a fish to grow growth is good, once exceed bid,make water quality changes to difference brings about a fish possibly to fall ill or die.
? (3)
Bottom quality base breeds the influence that views and admire a fish to the pond character bigger. In pledging by, especially silty in, contain much nutrient material and microelement, these grow to bait makings biologic the growth of development and aquatic has important sense. But silty in contain many organic other people, can bring about water system oxygen demand to increase quickly, often cause a pond anoxic float pool. The scholar points out, below anoxic condition, the oneself immunity force of piscine body drops, produce a disease more easily.
