Loach is known as "water ginseng". With the development of science and technology, artificial breeding mud louse has become a reality, but how do ordinary villagers feed mud loach under simple conditions?
The key to keeping a loach is breeding. Muddy natural spawning period is longer, usually from April to August each year. From late May to late June, when the water temperature reaches around 20-25°C, it is the spawning period. The progeny used for breeding should choose the second-instar, mature, well-being, and disease-free, non-invasive loach. Female loach is best selected individuals with a body length of 15 cm or more, a body weight of 20 g or more, an abdomen enlargement, a wide pectoral fin, and a rounded front end; male loach should be selected for individuals with a length and body weight that are slightly smaller than those of female loach, narrow pectoral fin, and pointed tip.
Due to the limited conditions, the villagers are advised to use artificial insemination. If the abdomen is emptied of granules in the abdomen by light pressure, and semen flows out from the abdomen of the male loach, artificial insemination can be performed. The extruded eggs and semen were mixed in an enamel pot. After adding water, two eggs were gently stirred for 1-2 minutes to allow them to enter the normal incubation stage. Generally, the seedlings were hatched in about 2 days. After hatching, the eggs in the water become their food. In this way, the survival rate of seedlings is extremely high.
After 3 days, the seedlings can be fed into the pond. Before stocking, first spread 20-25 centimeters of fertilizer, and apply basic fertilizer, algae and aquatic plants such as water lilies on the water surface, or shady trees, grasses, etc. Stocking densities range from 100,000 to 200,000 per square meter. After stocking, feeding is started, and egg yolk, soybean flour, and dried quail are fed at the beginning, and compounded feed is fed later. Feeding amount began to account for 2%-5% of the total weight of the seedlings, and then increased to 10%, feeding once a day on the afternoon. Up to 10 cm in length, enter the adult fish rearing stage.
Adult fish feed stage: Usually carried out in paddy fields, time is selected to be planted after transplanting, and the amount per mu is about 20,000. At the same time, it should be noted that the depth of the paddy field should not exceed 10 cm. In paddy fields, there are also many ducks. Ducks eat the pests and weeds in the water. Their excrement can also become a muddy food.
