In the case where there is a water source and it is not suitable to build a pond, a wooden box can be used to breed loach, which can be harvested for half a year. Each loach can produce 15 kg to 20 kg of loach. The specific method is:
First, wooden box production specifications 1 meter 1 meter 1.5 meters, a volume of 1.5 cubic meters. One or both sides have a diameter of 3 cm to 4 cm in the injection and drainage outlets, and a metal mesh with a mesh of 2 mm is installed. The bottom of the tank is filled with manure and soil (or a layer of soil on the straw). The uppermost layer is soil, and the depth of the tank is kept between 30 cm and 50 cm. The wooden box can be placed in the sunny water, so that water can flow from one hole and the other hole. It is also possible to connect several boxes together to create a box.
Second, the stocking density of each box can be put more than 3 cm of the species of 1 kg to 1.5 kg.
Third, feeding and management loach is omnivorous fish, wooden box water culture mud loach, mainly to artificial feeding.
Food formula: wheat flour 50%, bean cake powder 20%, rice bran powder 10%, fish meal or silkworm powder 10%, blood powder 7%, yeast 3%. When feeding, the food was watered into a soft dough and the feed amount was 1% to 2% of the body weight of the loach. Muddy appetite is related to water temperature, and the proportion of animal and animal diets and feeding amount should be adjusted according to season and temperature. When the water temperature was 15°C, the loach began feeding, and as the temperature increased, the amount of bait also gradually increased, generally 7% to 8%. When the water temperature is below 20°C, the plant food should account for 60% to 70% of the total amount of bait; when the water temperature is 23°C to 28°C, the plant food should account for 30% to 40%; when the water temperature is 30°C to 40°C, Should cast less or stop feeding. Generally, they are fed twice a day, 70% to 70% of the feed amount for the whole day at 7 to 8 in the morning, and 30% at 1 to 2 in the afternoon.
Fourth, the prevention and treatment of rickets in order to prevent rickets from occurring, while ensuring the quantity and quality of food, the use of quicklime, bleach and other regular disinfection of the box. In the case of enteritis, 20 grams of "Contretin" can be administered in 10 kg of bait, fed twice a day, and fed for 3 days to 5 days. Red fin disease is extremely harmful to the loach, the diseased loach fins, abdominal skin and anus around the congestion, ulceration, caudal fins, pectoral fins white and ulceration, shedding. In the event of this disease, the corpus callosum should be soaked in 0.110-8 tetracycline solution immediately for 1 hour to 2 hours or 0.210 to 8 "Ferritine" medicated bath for 24 hours, and 0.04% (the ratio of the drug to the loach body weight) should be used. ) The furanes mix in the feed and feed it for 3 days. If hydromycosis occurs, the disease can be soaked in 4% saline for 5 minutes to 10 minutes or soaked in 4 10-8 cupric sulfate solution for 20 minutes to 30 minutes. With 0.710-8 cupric sulfate and ferrous sulfate (both 5:2) solutions are sprinkled together to prevent and control trichoderma and tongue cup disease.
V. Precautions When it rains, it is necessary to prevent the tank from overflowing, the muddy escaping, and the water contaminated by pesticides and chemical fertilizers from entering the box.
