In the case of a water source rather than a pond, a wooden box can be used to breed a loach, which can be harvested for half a year and can be harvested in 15 to 20 kilograms per box. The specific method is as follows.
1, wooden box production specifications 1 meter 1 meter 1.5 meters, space capacity of 1.5 cubic meters. One or both sides are provided with a 3 to 4 cm diameter injection and drainage port, and a 2 mm metal mesh is installed at the mouth. The bottom of the tank is filled with manure and soil (or a layer of mud on the straw). The uppermost layer is soil and the depth of the tank is kept between 30 and 50 cm. The wooden box can be placed in the sunny water, allowing water to flow in from one hole and the other hole. Several boxes can be linked together to create a box.
2, stocking density can be put in each box more than 3 cm long pod species 1.0 to 1.5 kg.
3, feeding and management loach for omnivorous fish, wooden box flow culture mud loach, mainly to artificial feeding. There are fish food, animal viscera, pig blood meal, silkworm cocoon powder and other animal feed, and rice bran, bean cake, wheat bran, sauce, rapeseed cake and other plant foods. The formulated food consists of 50% wheat flour, 20% soybean meal, 10% rice bran powder, 10% fish meal or silkworm meal, 7% blood meal, and 3% yeast meal. With the bait, add water to soft dough. The amount of feeding is 1 to 2% of the body weight of the loach. Muddy appetite is related to water temperature, and the ratio of animal and animal baits and feeding amount should be adjusted according to the season and temperature. When the water temperature is below 20°C, the plant food should account for 60 to 70% of the total amount. When the water temperature is 28 to 23°C, the plant food should account for 30 to 40%. Generally, it is fed twice a day, 70% of the feed amount for the whole day at 7 to 8 in the morning, and 30% for the feed at 1 to 2 in the afternoon. When the water temperature starts at 15°C, the amount of bait also gradually increases as the temperature increases, generally 7 to 8%. When the water temperature is higher than 30°C or lower than 10°C, it is necessary to cast less or stop eating.
4. Prevention and treatment of diarrhea disease Regularly use quicklime, bleach and other disinfection cabinets. Once enteritis is found, 20 grams of furazolid can be added to 10 kg of bait and fed twice a day for 3 to 5 days. The loach is infected with red fin disease, with fins, abdominal skin, and hepatic portal congestion, ulceration, caudal fins, and pectoral fins white and rot. When the disease was found, the corpus callosum was immediately immersed in a 0.001/100 concentration of tetracycline solution for 1 to 2 hours or a 0.002 to 100% concentration of tetracycline bath for 24 hours. Or use 0.04% (the ratio of the drug to the weight of the fish) of Furaneis to mix in the feed and feed it for 3 days. If hydromycosis is found, the disease can be soaked in 4% saline for 5 to 10 minutes or soaked in 4 mg/kg of copper sulfate solution for 20 to 30 minutes. If parasites are found, 0.7 mg/kg of copper sulphate and ferrous sulphate (3:5:2) can be sprayed in the header to prevent and control trichoderma and tongue cup disease.
5. Matters needing attention When it rains, it is necessary to prevent the tank from spilling out, causing the mud to escape, and to prevent pesticides and chemical fertilizers from entering the tank.
