The breeding technology of wheat dace and where is it suitable for breeding

1. Pond: The area of ​​the pond is 2-15 mu, the depth of the pond is more than 1.5m and there is abundant water around it. 2. Stocking fish fry: Stock the neatly sized and strong summer carp, 6000-7000 per mu and add 10-20 large-sized silver carp per mu. There should not be carnivorous and ferocious fish in the pond. 3. Daily management: Ensure the cleanliness of the water quality and apply fertilizer reasonably to improve the water quality. You can feed artificial compound feed at ordinary times.

1. Breeding technology of wheat dace

1. Pond

The prepared area is 2-15 mu, the pond depth is more than 1.5m, and there must be sufficient water source around it.

2. Stocking fish fry

(1) From late May to early June, 6,000 to 7,000 large-sized silver carp can be stocked per acre, along with 10 to 20 large-sized bighead carp fingerlings per acre.

(2) After the release, no other fish with the same or similar diet as the black carp will be released. In addition, carnivorous and ferocious fish, such as the black snakehead, should not be allowed in the pond.

3. Daily management

(1) Cultivate water quality: It is necessary to apply fertilizer reasonably to improve the water quality. At the same time, you should also pay attention to whether the water quality is clean. If the water quality is too poor, it is easy for the wheat bream to be infected with parasites.

(2) Feeding: Based on the “four determinations” principle, artificial compound feed can be fed and the feeding amount can be adjusted reasonably according to the feeding status of the fish, weather conditions and other conditions.

(3) Disease prevention and treatment: Use drugs rationally to prevent parasites. For example, wheelworms can generally be treated with wheelworms, while ringworms can generally be treated with mebendazole.

(4) Reasonable use of aerators: At night, the aerator needs to be turned on 1-2 hours before the wheat ling floats to the surface. If the aerator is turned on after the wheat ling floats to the surface, it will usually affect its growth rate in the long run. If insecticide disinfection is required, or when encountering abnormal weather such as heavy rain or typhoon, the aerator can generally be turned on all night.

2. Where is the best place to breed wheat dace?

1. Generally, wheat ling can be raised in Hainan, Fujian, Yunnan and other places. The full name of wheat ling is Mai Ruijia Laling. Its appearance is similar to grass carp. It has a long and nearly cylindrical body, a round and straight abdomen, a slightly raised dorsal fin, and a wide and deeply forked tail fin.

2. The wheat carp likes running water, is good at jumping, and has relatively strong adaptability. It can usually grow normally in reservoirs, lakes, ponds, rivers and other places. Its cold resistance is stronger than that of the earth carp. When the water temperature drops to 7℃, it can generally still move normally.

3. Wheat ling is an omnivorous fish. It often feeds on phytoplankton, higher plants, organic debris, wheat bran, corn flour, peanut bran and other foods. Moreover, the growth rate of wheat ling is faster than that of native ling. The fry bred in the same year can generally grow to more than 300g.

What are the techniques for breeding sweet osmanthus fish and bait fish? How to breed them efficiently and productively?

To achieve high-yield and efficient breeding, the water must be kept clear and not allowed to become turbid.

The 2022 list of Xinhuinong series with professional services has been updated QFeBDE Xinhuinong, the weight growth rate of frogs fed with live protein worms increased by 5%-10%, and the survival rate increased by 10-15%. The dosage for carnivorous fish such as osmanthus fish and black carp is 20%-50%. The insect slurry is mixed with feed or fed directly. Guizhou Xinhuinong Ecological Agriculture Co., Ltd. provides technical guidance from the initial stage of breeding to the growth stage. The breeding technology is more complete and scientific, the harvest is greater, and the application prospects are good. The source of protein worms comes from Southeast Asia and is an alien insect species. It can increase the growth rate of fish by 5-10%.

There are many techniques for breeding sweet osmanthus fish, including regular water changes, changing the appropriate bait, and observing weather conditions. Efficient and high-yield breeding requires a wealth of breeding knowledge.

Osmanthus fish breeding skills

Mandarin fish (Siniperca chuatsi) is a fish that has evolved in a very special way. Like pufferfish and tilapia, it is a very distinctive fish.

Living habits

Osmanthus fish is a bottom fish that lives in still water and rivers, lakes and reservoirs with a certain amount of water flow, especially in shallow lakes with abundant aquatic plants. It usually lurks at the bottom of the water during the day and moves around to find food at night. It has the habit of making nests in holes and does not like to live in groups. The suitable water temperature for its life is 15-32℃. It is not very active and does not eat when the water temperature is below 7℃. In pond farming, osmanthus fish often lie at the bottom of the water and hide in shallow holes. Therefore, when using land nets to fish in ponds that mainly raise osmanthus fish, it should be noted that after pulling the first net, it should be kept for a period of time, and the second net should be pulled after the pond water is calm and the osmanthus fish leave the nest, so as to increase the pulling net capture rate.

Farming technology

1. Pond conditions: To breed sweet osmanthus fish, you should choose a pond that is sheltered from the wind, facing the sun, with sandy loam and a flat bottom.

2. Release the fry: When releasing the sweet osmanthus fish, put it together with the plastic bag into the water for 20 minutes to allow the fry to grow slowly.

3. Feeding and management: Feed the sweet osmanthus fish once every 7-10 days.

4. Note: When there is a thunderstorm, turn on the oxygenator in time.

Bait fish farming tips

There are many varieties of bait fish, including dace (local dace, wheat dace, Thai dace), white bream, crucian carp, grass carp, carp, and even tilapia, wild fish and shrimp. As long as they are suitable for the fish, the sweet-scented osmanthus fish can eat them. Now, through domestication, there are also people who feed fresh ice fish and soft feed. Dace is the main feed fish. The breeding of dace is a relatively easy process, because its food sources are relatively wide (it can also be treated with sewage), which can be summarized into the following types: phytoplankton, livestock and poultry feces, by-products of the food industry: soy sauce residue, beer residue. Even cassava residue and many aquaculture plants, food factory scraps.

Breeding techniques

1. Although dace is very resistant to hypoxia, the growth rate of fish is definitely not good under relatively hypoxic conditions, and they are more likely to get sick. Only with sufficient dissolved oxygen can this fish be well raised. The surge machine recommended here is three times more efficient than the impeller aerator during the day, but its power is only 1.1 kilowatts. It only needs to be turned on for a few hours during the day, and basically does not need to be turned on at night (except in special weather). This can meet the basic dissolved oxygen needs of dace.

2. Regular bottom modification, including oxidation, bottom disinfection, and biological bottom modification, is also necessary to stabilize the water quality. Disinfection and pest control are also required according to specific circumstances, but this situation is not likely to occur if the bottom quality and water quality are good.
