Muddy meat is delicate, delicious, nutritious, and has the reputation of being a ginseng in water. It not only has a high food value, but also has a certain medicinal effect. It is capable of regulating Chinese Qi, quenching thirst, drinking, urinating, impotence, and harvesting. It is famous. One of the tonic foods. Folks have a good effect on treating patients with hepatitis, diarrhea, pruritus, bruises, ascites, and urination. With the increase in people’s awareness of it, the price of mud has doubled and it has gradually become a good product for people on the table. The demand for mud loach in China is very large, the price is (15-20) yuan/kg, and it is also very popular in the international market. In 2005, only Lianyungang port exported 2199.17 tons of loach, with a value of 3.649 million US dollars, and vigorously developed the loach breeding prospects. Very broad. Rice field farming technology is introduced as follows:
I. Selection and preparation of rice fields
1. Paddy fields choose to have sufficient water sources, good water quality, convenient irrigation and drainage, loose soil fertilizer, abundant humus, and good water retention properties as a paddy field with aquaculture.
2. Anti-escape facilities Rice paddy fields should be 30 to 40cm above the water surface. The inside of the ridge should be as steep and smooth as possible. Blocks can be used on the inner side of the slats, and the upper edges of the slats can be made shield to prevent the muddy from escaping. The boards should hit the mud. 20cm to prevent muddy escaping from below. In addition, fish nets or fish traps are installed at the inlet and outlet, and they are placed diagonally in the paddy field to reduce dead angles at the inlet surface.
3. Excavate the fish ditch around the field, near the drainage outlet or other suitable place before the fish ditch is excavated. Fish ditch is about 40-50cm wide and about 40cm deep. Dig a 5m2 or so fish pit to the outfall. The fish ditch pit area accounts for about 8%-10% of the paddy field area, which is good for solving fertigation in paddy fields. , drugs and sun damage on the mud, but also easy to muddy fishing.
4. Spread 20cm of chicken manure, pig manure, cow dung and other mixed organic fertilizers in the fish ditch before fertilizing and stocking. The fertilizer covers 10cm straw and 10cm soil, which is conducive to the breeding of food organisms.
Second, seed stocking
Restocking time - generally 10-15d after rice transplanting. Before stocking, pay attention to the selection of seedlings with the same basic specifications and strong physique, and use 3%-5% salt water to wash the fish species for 5-10 min. Mainly rely on natural food feeding, stocking 3 to 4cm per acre 10 to 15kg. If the artificial feeding is intensive, 40-60kg of seed is stocked per acre.
Third, feeding and management
Mud feed is more extensive, and wheat bran, bean dregs, bran, soybean cake, and artificially-combined bait can all be ingested. Feeding bait should pay attention to nutritional balance, try to use full-priced feeds that are inexpensive, nutritious, and well-tolerated. When feeding 2 times per acre, the daily feeding amount is 3%-5% of the loach's body weight, depending on the eating condition of the fish, the feeding site should be selected in the fish ditch.
Fourth, field management
The field management of cultured loach is mainly water quality management. Observe carefully that it is necessary to add new water in a timely manner when the color of the water is dark or too strong and keep the depth of the field about 6cm deep. When the temperature exceeds 30°C or when the water quality is too fat, new water may be added in a timely manner to adjust and improve the temperature and water temperature. The application of chemical fertilizers and pesticides should be strictly controlled. Each application of urea 4-5kg and ammonium sulfate 8-1Okg. Use pesticides should use high-efficiency and low-toxicity pesticides. The water level should be deepened before spraying. When spraying, the nozzle should be upward to minimize the liquid falling into the liquid. It is necessary to conduct inspections on the ground and pay attention to the prevention of damage and escape. In particular, when hot weather, heavy rain, and irrigation are required, fish inspection equipment must be checked in time to prevent muddy escaping. Also pay attention to snakes, ducks, ferocious fish and other muddy enemies, strengthen management, kill or drive in time, and reduce unnecessary losses.
Fifth, capture
There are many methods for muddy catching, such as cage trapping, drug trapping, net trapping, etc. Usually, traps are used for trapping. Cage trapping is based on the muddy habits. The cage is set in the fish ditch in the paddy field, and the bait dumpling made of wheat flour, rice bran and fish meal is cooked in the cage. The cage setting time is generally selected at night, so that the effect of catching is better, and it is harvested once in about 1 hour. With this method of fishing, 50%-80% of the breeding amount can be captured at a time.
Most of the facial wrinkles are caused by facial muscles. Using botulinum toxin (Botulax and Meditoxin) injections to reduce the formation of wrinkles and facial muscles. The facial wrinkles are flattened. It has good effect to remove brow wrinkles, forehead wrinkles, eyelids, mouth wrinkles and nose bridge wrinkles.
*Modify face type
The square face can be treated by the principle of paralyzing muscles, muscle atrophy and muscle volume becoming smaller. The effect of muscle atrophy to correct the square face can last for about 1 year.
* Skinny legs
Inject botulinum toxin into the calf, paralyze some of the calf muscle tissue, induce muscle atrophy and slim the thick calf, showing a soft curve.
