Broodstock breeding Parent collection: The wild parent of Alice's red beetle is selected from large-surface winter fishing fish. Individuals are above 1kg and their age is above 3 years old. The body surface is disease-free without injury, and the body is not deteriorating. Pond cultivation: Pro-fish pond conditions: Requirements 2 acres -10 acres, 1.5 meters -2 meters depth, less silt, flat bottom, convenient drainage and drainage pond, equipped with a 1.5KW aerator. The broodstock stocking: the pond is sterilized by the clear pond, water quality is cultivated, and then the stockings are raised in red. The broodstock must be sterilized and sterilized with 5% saline. Amount of mu is between 50 kg and 100 kg. Water Quality Requirements: The source of influent water is non-pollution, and the water quality is kept “fat and tenderâ€, and the oxygen aerator is opened in time to ensure the dissolved oxygen in the water. Feeding situation: Feeding a certain amount of small wild fish as bait fish and feeding compound feeds with high protein content not only satisfy its wild animal dietary requirements, but also get nutritional requirements to promote gonadal development. In the winter, 3 days to 5 days, fine weather can be fed with a compound feed. After spring, 1% of the broodstock is baited, and in March-April, 2% is baited. When the bait is low, the fish is added in time. Stimulation of flushing: One month before the broodstock breeds, usually in April, it often flushes and promotes gonadal development. From April to May, the water is changed once a week, about 1/4 of each time. Pro-fish production Time Temperature: After mid-May, the water temperature is stable above 22°C. Parental choice: Female Oops, Ovary profile, abdominal soft and elastic. Male Alice mouth red body side of a large number of beads, hand touch rough feeling, light pressure on the abdomen with milky white semen outflow. Pulling nets and inducing production: According to the characteristics of good mouth jumping, dryness, and easy oxygen deficiency, the net operation should be light and the broodstock transported by the cloth should not exceed two, reducing mutual impact. A small cage was set up in the spawning pool. The parents were weighed first and then put into a cage. The fish was placed in the water for oxytocin production. The retort laboratories asked for time to be coordinated and the apices were shortened as much as possible. . Fry spawning hatching Spawning collection: The brooding fish elicit estrus until about 8 hours. After the injection of drugs, the spawning pool can be stimulated by running water, and the water can be kept in balance, and the fish nests can be put into the spawning pond in time. The number of fish nests should not be large, but only play a role in inducing spawning. Set the egg collection box in a timely manner before the estrus estrus clean up, collect the outlet of the fish eggs. After the spawning is completed, the fish is cleaned by drainage and the fish eggs flow into the collection box; the fish nests with fish eggs attached are put into the barrel or the tank for incubation; and the fertilized eggs attached to the wall of the sweeping pool are placed beside the water. Incubation management: The eggs are placed in hatching tanks or cylinders for hatching. Practices suggest that hatching tanks or cylinders have better hatching effect, and the water flowing in and out is smooth, and it is not easy to leave dead corners and the rate of emergence is high. The fish eggs were completely stripped after 24 hours, and the waist points formed after 90 hours-96 hours. The fishes could be cultivated under the pond. Li Hongyin

Artificial propagation of Aphrodisiac?
The red mouth is commonly known as "fish", "mouth", which belongs to the genus Acridoides, Polygonidae, Pheasantidae, and Rhododendron. It is an economic fish living in the upper layer of the water body. It has a rapid action and is dry and frightened. Good jump. Due to its tender meat, delicious taste, and rich nutrition, it has the efficacy of appetizers, spleen, swelling, diuresis, and brain-building, and is well received by consumers. The wild Aphrodisiac is dominated by carnivorous meat, and the artificially breeding Aphrodisiac can completely feed on artificial compound feed. In recent years, it has become a preferred species for pond rearing and river channel lake breeding.
Hangzhou Trifanz Medical Device Co., Ltd is located in the Hangzhou bio-pharmaceutical hi-tech park, as an innovative enterprise, our company has been supported by the government. Close to Shanghai and Ningbo ports, the transportation is very convenient.
