Red skin disease
The disease is caused by infection with Pseudomonas fluorescens. Diseased fish surface or most of the bleeding inflamed, scales off, especially on both sides of the fish and the abdomen is most obvious, all fin bases are congested, the ends of the rays are rotted, there is a "fin fin" phenomenon, sometimes the upper and lower jaws of the fish The lid is also congested and inflamed, even with the phenomenon of "open skylight." Diseased fish are slow, unresponsive, and swim alone in the water. The disease is mainly harmful to grass carp, herring, carp, carp, head lice and so on.
Control methods: (1) The average depth of water per acre of water is 1 meter with "strong bacteria kill" 50 ml Quanchiposa, spilled every 15 days, can have a preventive effect; treatment, the average depth of water per acre of water with 1 meter "Poisonous bacteria kill" 100 ml Quanchiposa, such as a serious illness, spilled once every other day; (2) with "strong bacteria kill" medicine bath, the concentration of 0.3 mg / liter, medicated bath for 10 minutes.
Aquatic mildew
The disease mainly occurred in the fish just entered the wintering pool for a period of time, due to the injury of the fish when the pond or net was pulled, scales fell off, and the invasion of water mold. The mycelia of the diseased fish surface are multiply and grow into clumps, which are cotton-like, white or off-white. Mycelium destroys the fish tissue, increases the mucus of the skin, makes the sick fish restless, disturbed swimming, swimming delay, loss of appetite, and eventually thin and dead.
Prevention methods: (1) Prevent fish injuries during fishing, transportation, and stocking; (2) Use 3% to 5% salt water to soak the fish in front of fish ponds, and pay attention to the appropriate stocking density; (3) For prevention, the average depth of water per acre of water is 1 meter with "tobacco net" 100 grams of water Quanchiposa; (4) When treatment, the average depth of water per acre of water is 1 meter with "tobacco net" 150 grams Quanchiposa. 10 grams of "tobacco net" per kilogram of feed was fed, 2 times a day for 5 consecutive days.
Small melon worm
The disease is caused by parasitoids parasitizing the skin and ankles. Many small white spots are visible to the naked eye on the body surface of the diseased fish, fins or crests. In severe cases, the fish body is covered with a white film. Diseased fish are emaciated, dull, floating on the surface of the water, sometimes clustered around the pond, and the fish constantly rubbing against other objects and die in batches.
Prevention methods: (1) 1 m per mu water depth in prevention is diluted with 10 ml to 15 ml of "insect killer" and 2000 times the whole pool is evenly sprayed; (2) 20 ml of water is used for 1 m per mu when treated. Diluted 2000 times the whole pool evenly spilled.
Third generation worm disease
The disease is caused by three generations of insects invading the skin, rays, and septum. The severe diseased fish has a grayish white mucous membrane on the skin, which loses its original luster and is in an uneasy state.
Prevention methods: (1) Do a good job in clear ponds and strengthen daily feeding and management; (2) Wash the fish species with 2010-6 potassium permanganate solution for 15 minutes to 30 minutes before stocking.
Oblique worm disease
The disease is caused by parasitoid parasitism on the skin or fleas of fish. The diseased fish's body surface and tendon produce a large amount of mucus due to irritation, resulting in a pale gray film that affects the respiratory function of the fish and causes the fish to die due to breathing difficulties. The major hazards are overwintering species and broodstock; when the fry is sick, sometimes there are symptoms of mud dragging. Control methods: Take lime thoroughly and disinfect the pond.
Myxosporidiosis
The disease is caused by the invasion of Myxosporidium. Myxosporidium often invades the skin and fleas, and it is parasitized in the epidermis of the cerumen. It grows and reproduces, forming a number of gray-white punctate cysts, destroying the tendon tissue, affecting the respiratory function of the fish, causing serious infections and killing the fish.
Prevention methods: Prevention: (1) Clean the pond thoroughly with quicklime 125 kg/mu to kill the spores in the sludge; (2) Kill with 100kg/mu of lime nitrogen in the clear pond; (3) Use fish before stocking The 50010-6 potassium permanganate solution was dipped for 30 minutes. Treatment: (1) 0.5 to 110-6 crystal trichlorfon Quanchiposa, once every 2 days to 3 days for a course of treatment, continuous use of two courses. Treatment of carp iodophorosis is effective; (2) with 1 ~ 210-6 sporadically Quanchiposa, can effectively prevent and treat this disease.
Wilt
The disease is caused by lack of nutrition. Sick fish showed thin body, ribs exposed, head and tail small, swimming weakness, in the fine weather at noon, often statically floating in the water the sun, slow down when frightened, the disease is affecting the quality of fish species, the weight is Caused a lot of death of fish.
Control methods: (1) Strengthen feeding management and keep food in winter. As long as the water temperature rises to 10°C, feeds are continued. Generally, concentrates are the main ingredient, and the amount of fish fed is 3% to 5% of the body weight of the fish. (2) Add some nutritive health-care agents to the feed, for example, add 1 gram of special vitamin C for aquatic products per kilogram of feed, which can enhance the immunity of fish and enhance the feeding ability, and effectively prevent the occurrence of the disease.
Anchor head disease
The pathogens of the disease are polymorphic anchor head lice, medlar head lice, and oyster head lice. They mainly parasitize the fish, causing inflammation and swelling around the tissues, affecting eating and breathing, and causing death.
Control methods: (1) Lime clear ponds can kill the larvae of the anchor-head larvae; (2) Stocking fish species can be washed with 10 to 2010-6 potassium permanganate solution for 10 minutes to 30 minutes; 3 with green pine hair or maple Poplar leaves, 10 kg to 15 kg per mu, tied into 5 bundles - 6 bundles, hanging around the food market.
Greenhouse Automatic Proportional Pump
Fertilizer pump mounted directly on the pipe, the kinetic energy of pipe flow to drives the pump to work at a set ratio to suck high erconcentration drug or quantitative fertilizer in to the pump. After mixed with the water and delivered to downstream. No matter How to change the water pressure, Drug or fertilizer will be mixed and discharged according to a certain proportion.
