The advantages of paddy fields are many: the first is to achieve the effect of one-water dual-use, one-site dual-income, direct increase in economic efficiency; second, the ecological effect is more prominent, mainly manifested as muddy can directly eat the water part Harmful insects play a part of biological control of insect pests, saving pesticides and reducing food contamination. The loachy inhabits the surface of the mud that is eroded by the earth and can breathe through the skin and intestines in addition to breathing with earthworms. Loach is an omnivorous fish and prefers to feed at night. It feeds on insects, small crustaceans, young leaves of aquatic plants, and diatoms, cyanobacteria, green algae, yellow algae, and zooplankton. Artificial feeding can feed commodity feeds, such as peanut cakes, rice bran, bran, bean cakes, silkworm cocoons, snails, clams, hydro-filaments, fish, poultry, livestock and other internal organs. Loach individuals are small, light weight, gluttonous, and when inflated, they can easily cause indigestion and affect normal breathing and cause swelling. Loach is a warm-water fish, which is yellowish in paddy fields. Its growth temperature is 15°C~34°C, and the optimum growth temperature is 24°C~30°C. When the water temperature drops below 5°C~6°C or higher than 35°C~36°C, it dives into mud 10 cm to 30 cm mud layer for dormancy. Rice field construction In paddy fields, we must choose paddy fields with sufficient water sources and good water quality and cover an area of ​​2 mu to 10 mu, and build 80 cm high escape walls with cement or plastic plates, films, screens, etc. (into the mud, 30 cm) around the paddy fields. . A 20-cm-wide step is made along the field and 15 cm from the top of the field. A field-shaped gutter is digging around and in the center of the field, with a width and depth of 50 cm. One inlet, one drain, and one overflow pipe are used. The nozzles are intercepted with fine wire mesh. The drainage pipe is usually sealed with cement. Restocking The species is best derived from the original loach or from the natural waters. It requires a healthy and disease-free body. The age is 2 years old, the female body weight is 15 to 25 grams, and the male body weight is 12 grams or more. Mushi Fermented pig manure 1,000 kilograms, into the water filtered into the field, the water depth of 30 cm to 40 cm, fertilization of water, water transparency of 25 cm. After the seedlings return to green, 2-3 million to 25,000 seedlings of 3 grams to 5 grams per tail are placed in the acre, and soaked in 3% salt solution for 10 minutes before stocking, and then enter the fields after disinfection. Feeding management During the fertilization and aquaculture process, in order to ensure continuous plankton, organic fertilizers must be applied in a timely manner, in small quantities, and evenly. Fertilize once every 10 days to 15 days, each time 150 kg of fertilizer per acre. In addition, according to the specific conditions of water color, about 1.5 kg of urea or 2.5 kg of ammonium bicarbonate is applied per acre to keep the water body yellow-green. Due to the higher density of mud in Tanaka, artificial feeds such as bean cakes, cocoon powder, fly maggots, oysters, snails, maggots, slaughterhouse scraps, rice bran, bean dregs, rapeseed cakes, bran, etc. should be fed to supplement. The lack of natural food. July-August is the peak season for the growth of loach. It requires 15% of silkworm meal, 10% of meat and bone meal, and 25% of soybean cake. It feeds twice a day, and the feed rate is 10%. From September to October, plant-based feeds such as bran and rice bran are used as the main feeds. They are usually fed once a day and in the afternoon. The amount of feed is 2% to 4% of the total weight of loach. About 2% in early spring and late autumn. According to the flexibility of the mud feeding situation, generally after each feeding, it is advisable to eat basically within 1 hour to 2 hours. The actual water level above the control water level is generally controlled at more than 5 cm. The new water is added in a timely manner. Generally, water is added once every two months. In the high temperature season in summer, the water level should be deepened. Disease control Because loach is suitable for paddy field cultivation, there is generally no disease in the breeding process. In order to prevent the occurrence of erythrodermic disease, the whole pool is splashed with 10 kg to 15 kg of lime per acre per month. Rice pesticide application time is generally 3 days to 5 days before transplanting, or 5 days to 7 days after transplanting. Day-to-day management patrols the field twice, check the anti-escape facilities, and especially check the leaks carefully during rainy days. Prevent the invasion of natural enemies (such as water snakes, ducks, etc.), observe muddy activities and feeding conditions. The inflow of water containing highly toxic pesticides such as methamidophos, phenol poison, carbofuran, sodium pentachlorophenol, etc. is strictly prohibited. Fishing method First, flush fishing, in the vicinity of the mouth of the outlet, shop on the use of equipment, water from the inlet, due to muddy water there are dizzy features, after a certain period of time after the net to lift the capture. This method is suitable for water temperatures around 20 degrees, when the muddy love activities; the second is bait trapping, put the saute or bran of saute in the bamboo cage, the cage is placed in the ditch to trap into the cage; the third is to capture the dry field Slowly dry the field water, so that the loach can be trapped in the exposed part of the trench.
