What medicine does fish in fish ponds use for stuffed buns and worms?

There are many kinds of fish parasites, and different pests need different treatment schemes.

First, wheel disease.

Rotifers and rotifers.

Symptoms The fish is black and thin, does not eat, and has a layer of white clouds attached to it. Under the microscope, rotifers can be seen. From fry to summer flower infection, the head and mouth of the sick fish are slightly white, with more mucus secretion, and they swim wildly along the pool in droves, commonly known as "horse racing disease".

Epidemic situation The epidemic season of this disease is from April to165438+1October every year.

Preventive measures: (1) Clean the pond thoroughly with quicklime; Soak fry and fingerlings in 2% salt for 20-30 minutes before stocking;

(2) Three-ring lore mixed feeding for 3 days, once every half month.

Treatment: (1) spray the wheel inclined tube in the whole pool to kill 100g/μm, or wash the wheel once 150ml/μm, or 30ml/μm to kill fish and insects or 20ml/μm to kill stars. ..

(2) The mixed bait of tricyclic Shi Jue+high energy immune VC+ Kelikang was taken orally for 5-7 days.

Second, the inclined tube worm

Pathogen of trypanosoma.

Symptoms There are a lot of parasites on the gills and skin of fish, which will cause mucus increase, difficulty breathing and slow swimming, and even lead to fish death.

Epidemic situation Spring and autumn are the epidemic seasons of the disease.

Control: (1) Clean the pond thoroughly and spray 25ml/μm dithiocyano methane or 25ml/μm mycophenolate mofetil regularly;

(2) Oral Shenshukang and high-energy immune VC were mixed for 2-3 days, half a month 1 time.

Treatment: (1) The inclined tube of the wheel in the whole pool is killed 100ml/μm or the wheel is cleaned once150 ml/μ m;

(2) Take Shenshukang orally and feed it with high-energy immune VC for 5-7 days.

Third, finger disease.

Dactylogyrus

The gill filaments of symptomatic fish are covered with white balls, and worms can be seen under the microscope. In severe infection, gill filaments are dark gray, mucus increases, gill cover opens, and breathing is difficult.

Epidemic situation: The epidemic season is summer and autumn, and wintering fish ponds are easy to occur when the temperature is suitable in early spring.

Preventive measures: (1) Quicklime is added with water to clear the pool;

(2) In the onset season, the three-ring killer was mixed and fed for 3 days, once every half month.

Treatment: (1) 20ml/ mu. M is for killing bacterial eggs, 30ml/ mu. M is killing fish, or 20ml/ mu. M stands for killing fish and insects;

(2) Take tricyclic bait orally and feed it for 5-7 days.

Four, anchor head withering disease

Polymorphic anchovies in pathogenic beetles.

Needle worms can be seen with naked eyes on the body surface and oral cavity of symptomatic fish, and the periphery of parasitic part of centrosome is red, swollen and inflamed; The fish became thin, swam slowly and eventually died. When anchovy gradually ages, worms are covered with algae and sessile protozoa. When a large number of anchovies are parasitic, the fish body is like a layer of coir, so it is also called coir disease.

Epidemic situation: the disease is easy to occur when the water temperature is 12 ~ 33℃, and the optimum water temperature for adult spawning and reproduction is 20 ~ 25℃.

Preventive measures: (1) Clean the pond thoroughly and kill the anchovy larvae in the water;

(2) Every 15-20 days, spray 20 ml /μm of mixed fish killer on the whole pond.

Treatment: (1) sprinkle 20ml/μm spiders, insects and killers, or 20ml/μm bacteria and eggs;

(2) Take tricyclic bait orally and feed it for 5-7 days.

Five, China thrush disease.

The pathogen is China herring.

Symptoms of fish can be seen with naked eyes that there are milky white worms inside the gill filament end; The fish is thin, and the upper leaves of the caudal fin are often exposed to the water, so it is called "tail-lifting disease".

Epidemic situation The epidemic season of this disease is from April to 165438+ 10 every year, especially from late May to early September.

Preventive measures: (1) Clean the pond thoroughly and kill the anchovy larvae in the water;

(2) Every 15-20 days, spray 20 ml /μm of mixed fish killer on the whole pond.

Treatment: (1) sprinkle 20ml/μm spiders, insects and killers, or 20ml/μm bacteria and eggs;

(2) oral tricycloprolol+high energy immune VC mixed bait for 5-7 days.

Six, small melon disease

The pathogen is a small melon bug with many children.

The body surface, fins and gills of symptomatic fish are covered with small white vesicles, which secrete a lot of mucus and form a white film. Fins rot and worms can be seen under the microscope.

Epidemic situation The epidemic season of this disease is March-May and 8- 10 every year.

Preventive measures: thoroughly clean the pond with quicklime to kill the cysts of worms; Spray 20ml/μm fibrinogen on the whole pool, 15-20 days.

Treatment: (1) The whole pool was sprayed with fibrinogen 25 ml/μ m;

(2) Oral tricyclic lore+ high energy immune VC compound bait for 5-7 days.

Seven. Myxosporiasis

Pathogens Myxosporidia, Microsporidia and Monosporidia.

Symptomatic fish body surface muscles, gills, intestines, gallbladder and other organs, forming large and small white cysts visible to the naked eye; Under the microscope, worms can be seen.

The epidemic situation of the disease has no obvious seasonality, and it can occur all year round.

Control method: (1) thoroughly clean the pond with quicklime 125kg/ mu to kill spores in the sludge; (2) Soaking fish in 500ppm potassium permanganate for 20 minutes can kill 60-70% of spores.

Treatment: (1) 30ml/ mu. Use 100 ml of loach powder in the whole pond every other day;

(2) Take orally the mixed bait of tricyclic killer+high energy immune VC+ Yuganbao for 3-5 days. If the condition is serious, use another course of treatment every other week.

Eight or three generations of bugs

Pathogen third generation worm

Symptoms When a large number of fish are parasitic, their gills and skin are black and dull, their bodies are thin, they swim slowly and their appetite decreases. Due to the stimulation of insects, sick fish often secrete a layer of white mucus. Ill fish often eat fins. Under the microscope, worms can be seen.

Epidemic situation The epidemic season of the disease is spring and summer every year.

Preventive measures: (1) Quicklime is added with water to clear the pool;

(2) In the onset season, the three-ring killer is mixed and fed for 2-3 days, once every half month.

Treatment: (1) 20ml/ mu. Rice and eggs or 20 ml/mu. Rice fish and insects kill stars and are sprinkled all over the pond;

(2) oral tricyclic lore+ high-energy immune VC+ quick-stop bait for 3-5 days. If the condition is serious, use another course of treatment every other week.
