[Composition]
The main component of this
preparation is human immunoglobulin, which is prepared by cold ethanol
fractionation of human plasma from healthy donors. The manufacturing process
contains a step to remove anticomplementary activity and a dual viral
inactivation process. It contains a suitable amount of glucose or maltose as
stabilizer (see table below), but does not contain any antiseptic or
antibiotic. The distribution of IgG subclasses is close to the serum level of
normal subjects and maintains the bioactivity of Fc fragment of IgG.
[Indications]
1. Primary
agammaglobulinemia, such as X-linked hypogammaglobulinemia,
common variant immunodeficiency diseases, immunoglobulin G subclass deficiency,
etc.
2. Secondary

Even the dorsal and anal fin bases are white; in severe cases, the carp caudal fins are rotted or incomplete, with the diseased fish head down and the caudal fins up.
The fish swims approximately vertically with the water and will soon die.
2. Pathogens and epidemics: There are two kinds of pathogens in this disease: A. fuliginea and M. mutans. The disease is mainly caused by poor water quality.
The breeding of pathogens, or improper operation in the breeding process caused damage to the fish and the invasion of pathogens caused by invasion.
The disease mainly occurs during the stage of carp summer fish species to large-scale fish species. The main epidemic season is from May to August. The area is endemic and ferocious. It will cause fish death in 2 to 3 days and the mortality of sick fish is high.
3. Control methods: 1 When pulling the net and sifting operation, be careful not to scrape the fish body. After the transported seedlings have passed the pond, they must first take a drug bath;
2 During the onset season, the whole pool is splashed with lime 1 or 2 times per month to keep the PH of the pool water at 8 or so, generally 15 to 2
0ppm;
3 Dip diseased fish with chlortetracycline 12.5ppm or oxytetracycline 25ppm for 15-30 minutes;
4 Quanchiposa erythromycin for livestock, so that the pool of water was 0.3ppm concentration.
Second, the explosive hemorrhagic disease 1. Symptoms: Symptoms of salmon disease occur mainly in the lid and the fins, side of the body with varying degrees of bleeding spots, congestion, congestion, and some rot with sludge, Liver and gallbladder enlargement and a bit like congestive, pale yellow substance in the intestine, later appeared under the eye ball and lid lid congestion, isolated travel alone, and soon died.
2. Pathogens and epidemics: The disease is mainly caused by bacterial infections in adverse environmental conditions, that is, the diseased fish is first caused by trichomonas,
Infestation by ringworms, leeches, and thorny head insects, and subsequent infection with bacteria.
Explosive hemorrhagic diseases are prevalent and have a high mortality rate. They are most prevalent in the summer and autumn. The incidence rate is above 50%, and some disease pools can even die in the whole pool.
3. Control methods: 1 To thoroughly clear the pond disinfection: Clear the bottom of the pond sludge, using lime powder and Jie Seoul mixture or use formalin and lime slurry mixture disinfection, can completely eliminate the wild, but also eliminate bacteria, fungi And viruses;
When entering the seedlings, try to use local high quality seedlings;
3 Before stocking, use Yingshi disinfectant or bath for 15-20 minutes;
4 During the breeding process, feed high-quality bait fish and disinfect the bait fish;
5 during the onset of the disease, every 10 to 15 days with lime 20 ~ 25Kg/m3 Quanchiposa;
6 after the onset of disease, with 2.5 ~ 3.7g/m3 rhubarb ammonia solution Quanchiposa, per kilogram of rhubarb with 20Kg0.3% ammonia soak 12
For 24 hours, use it twice.
Third, enteritis disease 1. Symptoms: diseased fish do not eat, body color black, floating in the water, intestinal air bubbles and stagnant water, diseased fish from the rectum to the anus segment congestion and swelling; severe intestinal swelling, purple The red, lightly pressed abdomen has yellow mucus and blood pus.
2. Pathogens and epidemics: Some people think that it is caused by P. catarrhalis. Etiology is often caused by the salmon being swallowed by the baitfish with enteritis. It is also an important cause of the disease.
3. Control methods: 1 choose palatability bait fish, usually 50 to 60% of the body length of the squid, to prevent excessive bait fish scratch injury intestinal cavity induced fish disease;
2 Disinfect the body of water in the trout pond and bait fish pond. Disinfection of the water body can use 0.4-0.5ppm bleaching and refining water Quanchiposa, repeated at intervals of one day;
3 Before the bait fish were bred, they were sterilized with 10% salt water and disinfected, and the diseased, disabled and weak bait fish were removed;
4 to bait fish to bait: one is to treat the sick bait fish, and the other is to let the bait fish swallow the bait and then swallowed by the carp, so that the catfish can be treated indirectly. Because it is an indirect medication, the dosage of the bait when formulated is 3 to 4 times the conventional dose.
4. Oblique worms and trichodinosis 1. Symptoms: The appetite of diseased fish is reduced to stop feeding after infection with the two insects. The diseased fish appears pale in the skin and ankles, and the cocoon filaments are massive rot and accompanied by silt. The diseased fish is dark in color, and it is anxious when the time goes by.
The action is sluggish and floats on the surface of the water. If it is not dealt with in time, the mortality rate is high. If the treatment time is delayed, even if the parasite is killed, it is difficult for the carp to recover because the carp tissue is destroyed.
2. Pathogens and epidemics: The parasitoids and trichinella are often parasitized on the same host at the same time. The main parasitic on silk, rays,
The body surface is also parasitic. The squid can infect these two kinds of insects all year round, and it is more common in spring and summer rainy days. For fish fry and fingerlings,
The most popular fish species are below 10cm.
3. Prevention and control methods: 1 It is a fundamental method to manage water well and ensure fresh water.
2 pairs of fish ponds found to be sick, with 2% daily saline or 0.7ppM copper sulfate and ferrous sulfate mixture (5:2) spilled once;
3 When the fish body is seriously ill, use 10ppm formaldehyde or 20ppm benzalkonium disinfectant to dip the fish for 10 minutes, using 3 to 5
% salt water immersed in fish for 5 to 10 minutes;
4 Sprinkle with 20ppm formalin Quanchipu.
V. Sphaeropathia 1. Symptoms: When the fry is infected, the dorsal fins have a yellowish-like filamentous material. The fry floats on the surface of the water. The action is sluggish, irritability, increased mucus on the surface, and the appetite is reduced due to debilitating physical weakness. When adult fish became infected, gray-white cotton flocks appeared at the site of infection, followed by wound expansion and rot that led to death.
2. Pathogens and epidemics: Saprolegniasis is also known as skin mildew. Caused by squid skin infection with water mold, can occur in the squid fertilized eggs, fry, fingerlings and adult fish stage, the main damage to fish eggs and early fry, is the main disease affecting the hatching rate of carp.
During the incubation stage, the hatching water is mainly mixed with sundries, causing damage to the fish eggs and infecting water mold. In the stage of fry to adult fish, mainly due to improper operation, the fish is injured due to improper operation. Infection with water mold.
The disease can occur throughout the year and is most prevalent in early spring and late autumn.
3. Control methods: 1 Incubation water is filtered through a 60 mesh nylon screen to prevent debris from entering;
2 When eggs are infected, 20～30ppm methylene blue bath can be used for 5 to 10 minutes;
3 before the injured brood fish under the pond, apply a proper amount of sulfa drug ointment to apply the fish body;
4 In the stage of seedlings and adult fishes, pay attention to the screening and transportation of the net and do not injure the fish. The sick fish was soaked in 3% saline for 10 minutes.
Sixth, gizzard disease 1. Symptoms: Disease fish gills rot whitish, bracts especially the surface of tantalum wire more mucus, and adhesion of sludge; severe gill cover is often corroded into the central surface of the near-round Irregular transparent holes, commonly known as "open skylight." Diseased fish often swim alone out of the water, swimming slowly, black complexion, black head, loss of appetite or not feeding, body shape and cause death.
2. Pathogens and epidemics: The pathogen of this disease is fish myxobacterial infection. The disease will be prevalent in all parts of the country. This disease will occur throughout the year. The water temperature will begin to prevail at temperatures above 20°C. The water temperature will be most prevalent from 28 to 35°C from April to October every year. The disease has developed rapidly.
In the short term, the peak of death can be formed.
3. Control methods: 1 thoroughly clear the pond with lime or bleach before stocking; 2 When the water temperature is 15 ~ 20 °C, use 10ppm bleach solution to dip fish species for 15 to 20 minutes, can prevent the disease;
3 with rhubarb ammonia solution 3g/m3 Quanchiposa, used 2 times, the specific method is: 1Kg rhubarb soaked with 20Kg0.3% ammonia for 12 to 24 hours, the liquid was brown red, the liquid and drug dregs diluted with water After Quanchiposa, use it again every 2 days.
Seven, rickets 1. Symptoms: The size of the body of the bug, such as the size of a bug, is often parasitized by its barb wounds, sucking blood, causing multiple wounds and other pathogens to invade, causing other diseases. At the same time when piercing the fish body, the secreted toxins are brought into the fish body, causing the internal tissue of the wound to rot, causing the fish to become extremely uneasy, wild swims, loss of appetite, weight loss of the fish, and eventually death.
2. Pathogens and epidemics: The cause of the disease is mistletoe caused by the surface of the eel. Every year from June to August is the epidemic of the disease.
Juveniles will die when they are fleshed. The harm to the carp fingerlings is greater.
3. Control methods: 1 Thoroughly clear the pond with quick lime to kill eggs and larvae;
2 Soaking the squid species with 5% saline can effectively make the sculpted fishes on the surface of the fish fall off.
3 Crystals trichlorfon 0.3 to 0.5ppm Quanchiposa.
Common diseases and prevention of common carp
First, the white skin disease 1. Symptoms: At the beginning of the disease, the diseased fish tail appears white spots, and quickly expands and spreads.
