1. Specialized pond rearing: It is generally used by the producers who specialize in mud aquaculture. The bottom of the pond is good for mud. If it is cement, it should be 15 to 20 cm deep. The area of â€‹â€‹the pond should not be too large, about an acre is appropriate, and 3-5 million seedlings of 3 to 4 cm in length can be placed per acre. Before laying the seedlings, the base fertilizer should be applied, mainly organic fertilizer, and a large amount of zooplankton should be cultivated as a loach food. After releasing the seedlings, feed feeding was gradually strengthened, and organic fertilizers were topped up. The main types of feeds fed were rice bran, bean cake, bran, bean dregs, silkworm cocoon powder, alfalfa and food processing waste. Fertilizers are livestock manure, crop straw composting, etc. If the water temperature is higher than 30 Â°C or lower than 10 Â°C, the amount of feeding should be reduced. General feeding 8 to 10 months can be captured, high yield per mu up to 250 to 400 kg. Each body is about 15 centimeters long and the body weight is 10-15 grams to reach the commercial specifications.
2. Family rearing: The use of house front room or vegetable garden pit and reservoir for loach breeding. Generally, it is possible to invest 4000-5000 pieces of seedlings that are 3 to 4 cm long per acre, and can also be stocked with astragalus and carp. Usually pay attention to feeding and fertilization, such as leftovers, livestock and poultry manure, leaves, etc., feed should be used in combination with animal and animal. At the same time, the water quality should be well controlled. When it is found that the muddy water is â€œswallowingâ€ on the water surface, it indicates that there is lack of oxygen in the water body. Fertilization should be stopped and new water should be replaced. Muddy individuals can be captured when they grow to 15 to 20 centimeters. After 8 to 10 months of feeding, the yield per mu can reach more than 100 kg.
Due to the small muddy individuals and the characteristics of drilling mud, fishing methods have a certain degree of difficulty. According to other characteristics of muddy mud, the following fishing methods can be used:
Flushing fishing: that is, close to the inlet, laying a dense eye fishing nets, and then discharge water from the inlet, due to muddy water has the habit of backwater escape, so gathered at the inlet, and then lift the first laying of the net at the appropriate time, so that Mud was caught.
Food trapping: Place the scented rice bran or other palatable bait in the net. When the loach induces food, the net will be lifted and captured. It is also possible to put the bait in a fishing rod or sack and place it under the water, so that a lot of loach can enter the loquat and the bag, and it is often put into the evening, and it is taken out in the early morning of the next day to capture a certain amount of loach.
Dry pool capture: When the water temperature drops below 15Â°C in the autumn, the muddy mud will gradually dig into the sediment of the pond. Drain pool water capture can be taken. Generally, the pond water is drained first, and then several small ditches are dug in the bottom of the pool. The mud will be collected in the drainage ditch for manual capture, or the silting mud will be dug into the iron screen and the water will be used to remove the mud and capture.
Disease control Loach breeding process, we must pay attention to do a good job of disease prevention, common diseases are red fin disease, water mold, bubble disease, bone disease, trichoderma, tongue cup disease, pesticide poisoning and other biological predators Wait. The main control methods are as follows:
1. Diseases caused by microorganisms Prevention and treatment of red fin disease: This disease is harmful to loach and has a high incidence. It is caused by bacilli. Symptoms are: First, the fins or the epidermis of the body surface are exfoliated, appear gray, muscles start to rot, red parts of the anus, then blood spots appear in these areas, and gradually become dark red, and in severe cases, the fins fall off and do not feed. Until death. Mainly popular in summer. Control methods: Fish injury should be avoided. Seeds should be washed and sterilized with 4% saline solution before stocking. When the disease occurs, chloramphenicol can be mixed in the feed.
Saprolegnia: Control of quail eggs Bathe with 400 g of solution of baking soda and 400 g of baking soda per cubic meter of water for 1 hour. The disease can be soaked with 3% salt solution for 5 to 10 minutes.
Print disease: lesions are generally oval, round, edema and erythema. The affected area is mainly at the base of the tail shank. Popular in July and August. Can be used 1 g / cubic meter of bleach or 2 ~ 4 g / cubic meter Gallic Quanchiposa.
2. Diseases caused by parasites Trichoderma disease: parasitic on the axilla and body surface. After the illness, the amount of food consumed decreased, and the animals traveled alone. When the disease was severe, the insects became dense. If they were not treated promptly, they would cause death. The epidemic occurred in May-August. Preventive measures are to clear the pond with lime; control method is to use the pool of water per cubic meter of crystal trichlorfon 0.7 grams Quanchiposa.
Tongue-crested caterpillar disease: parasites on muddy skin or gills, usually ingesting food in the surrounding water for nutrition, has little effect on loach. However, if a large number of parasites are parasitized on seedlings, it will cause breathing difficulties and, in severe cases, lead to the death of seedlings. It can be affected all year round, and it is more common from May to August. The main prevention is to use a 8 g/m3 water copper sulfate solution for 15 to 20 minutes before stocking, and 0.7 g/m3 water copper sulfate and ferrous sulfate (5:2) for the treatment after onset. Quanchiposa.
