Lunar New Year's Eel is also known as the star fish and the seven-star fish. The meat is tender and delicious. It has many medicinal effects such as nourishing the body, promoting blood circulation, diuresis and urination, etc. It has high Health Care value. In recent years, the market price has continued to rise.
Because it has special respiratory assisting organs (organs on the iliac crest), it has a strong ability to adapt to the environment. Therefore, there is no special requirement for breeding conditions, and it is suitable for high-density culture in small bodies of water in front of houses, yards, and courtyards.
Radon is a wide-temperature fish, the survival temperature of 1 °C ~ 38 °C, the intake of water temperature is 13 °C ~ 32 °C, the growth of water temperature is 14 °C ~ 30 °C, the appropriate growth temperature of 15 °C ~ 25 °C. It has such habits as hidding, hole-making, burrowing, and clustering, and it is an omnivorous fish mainly composed of animal feed. Sexual maturation age is two winter years, and it can spawn many times a year. The spawning season is from April to August, and the breeding water temperature is 18°C ​​to 28°C. The broodstock has a pairing, nesting, nursing and other habits. Artificial breeding requires first pairing for a period of time before artificial oxytocin production. Incubation and seedling cultivation can be carried out according to conventional methods of fish reproduction. Breeding techniques are as follows:
1. Build the pool. The garden culture moonshampers should choose a water body with an area of ​​20-500 square meters. The depth of the pool is generally about 2 meters, and the earthen ponds and cement pools can all be used. When breeding, pay attention to leakproof (water), anti-escape and anti-theft. The key to preventing flight is to prevent the moon from escaping from the hole and from jumping when the water is full. Therefore, the maximum water level in the culture pond should be less than 0.6 meters above the top of the pool wall. The aquaculture pond water depth can be maintained from 1 to 1.2 meters. At the bottom of the culture tank, some bamboo tubes, bricks, jars, barrels, and other debris should be placed on the moon to conceal it. If it is a concrete tank, the bottom of the tank should be set to a depth of 10 to 20 centimeters of mud to prevent the bottom plate from scratching the fish. For small water bodies below 200 square meters, the water hyacinth should be stocked to account for about 10% of the total surface of the water to regulate water quality and prevent water quality from becoming too fat. More than 200 square meters of water can be stocked with 10 to 20 tail 50 grams of squid, squid to adjust the water quality. In addition, when choosing a water source, you should choose non-polluting rivers, rivers, ponds, or wells. Tap water should be exposed for 2 to 3 hours before being placed in aquaculture ponds.
2. Stocking. According to the conventional fish culture technology, the ponds were sterilized. After 5 to 7 days of disinfection, the water can be fertilized, and after a few days, the drug is completely disappeared. The fish can be put into the moon carp after being tested safely. Stocking densities can be determined based on water conditions and management levels. Fish species should be soaked with 2% salt water for 10 to 15 minutes in front of the pond.
3. Feeding and management. The artificially-cultured Yueshao can be fed with animal feed such as chopped fresh, frozen wild fish, shrimps, snails, quail meats, pupa, and red worms. Can also use artificial compound feed (crude protein must be greater than 40%), can also use artificial compound feed mixed chopped and chopped animal feed, transferred into trapped feeding. The daily feeding amount is generally 3% to 8% of the fish's body weight. Feeding must be done regularly, position, quality, and quantity, and adjusted accordingly according to the water temperature and fish eating conditions. The day-to-day management is mainly to do a good job of patrolling the ponds, often adding fresh water, avoiding excessive water quality and deterioration, preventing the escape of fish, robbing fish and the occurrence of fish.
4. Disease prevention and treatment. On the one hand, the onset of the disease is relatively strong, and it is generally rare. However, in high-density farming, such as poor management, it is prone to diseases such as ulcer disease, hydromycosis, and parasitic diseases. Should be based on prevention, prevention and control. In general, water quality management should be strengthened, and regular use of 20ppm quicklime or 1ppm bleaching powder should be used to prevent bacterial disease throughout the entire tank. It is also possible to prevent the entire pool from spilling 0.5ppm of crystal trichlorfon (90%) or 0.7ppm of copper sulfate solution. parasitic disease.
