How to raise mandarin fish

Mandarin fish, also known as Mandarin Fish, sweet-scented osmanthus fish, is a very fresh and delicious fish, its meat is fresh and tender, at the same time has a very high nutritional value, is a relatively valuable freshwater fish. With the increasing demand of consumers for mandarin fish, mandarin fish culture has become a more popular culture project. So do you know how to raise mandarin fish?

How to raise mandarin fish

Mandarin fish is a freshwater fish, like to live in clean still water or micro-running water environment, especially in lakes with lush aquatic plants, suitable for breeding in ponds.

Breeding farms should have adequate water sources and good water quality supply, and non-polluting river water, lake water or large reservoir water is better. The suitable pond area for adult mandarin culture is 6-8 mu. The pond is too large to manage; the pond is too small, the water quality is easy to deteriorate, serious will cause hypoxia, and often lead to mandarin fish disease. The water depth should be kept at 1.5-1.8 meters. Keep 15-20 cm loam silt at the bottom of the pond. The newly excavated fish ponds without silt or sandy silt can apply appropriate amount of organic fertilizer to enhance the buffering capacity of the water body and cultivate suitable water quality. If there is too much silt in the old pond, the excessive silt must be removed before stocking. The bottom of the pond has a certain slope, and there is a 30cm fish pit in the lower part, which is easy to catch. The pond stem should also be built into a slope to facilitate the planting of aquatic plants or aquatic vegetables on the edge of the pool.

Culture techniques of mandarin fish

1, pond conditions: pond area is generally 2-4 mu, water depth is about 2 meters, mainly rectangular, fresh water quality, little or no bottom mud, drainage and irrigation oxygen equipment is complete.

2. Bait fish cultivation: according to the principle of good palatability and low economic cost, fish fry such as silver crucian carp, white crucian carp, blunt snout bream, silver carp and silver carp can be selected as bait fish. The fry of crucian carp or mackerel can be propagated by themselves by using the free period before sweet-scented osmanthus fish is reared in the pond, and the fry of all kinds of fish can be released about 20 days before Mandarin Fish is released. The amount of fish per mu is 40-600000. The feeding method is fed with soybean milk or other feed, and the bait fish in the middle and later stages should be raised in a special pond. It is appropriate to adopt the method of multi-pond high-density feeding, starting fishing in stages and gradually thinning, so as to ensure the synchronous growth of bait fish and mandarin fish.

3. Siniperca chuatsi fingerling stocking: the stocking time is generally June, and the stocking specification is 6-10 cm, which has the advantages of high survival rate and fast growth rate. The general stocking capacity is 500-800 per mu.

4. Feeding bait fish: during the period of adult fish culture, it is appropriate to be full every day. If there is too little food fish starving, it will affect the growth of Mandarin Fish or kill each other.

5. Water quality control: mandarin fish ponds should regulate the water quality and change water frequently. The high temperature season from June to September is the peak feeding season. It is necessary to inject and drain water once a week, changing water 0.4 meters each time, and keeping the transparency of the pool water more than 40 centimeters.

Selection of fodder fish

1. Early bait fish: 100-2 million fry (fish flowers) of silver carp, bighead carp, soil dace, wheat dace, Thai dace and crucian carp are pre-stocked in the pond where sweet-scented osmanthus fish are prepared, which are used as the early bait fish of sweet-scented osmanthus fish. After feeding coarse fodder such as peanut bran and wheat husk, the bait fish were cultivated for 20 days. When the bait fish grew to 1.5ml 2.5cm body length, after disinfecting with 0.7ppm copper sulfate and 0.5ppm strong chlorine, the fish fry of sweet-scented osmanthus with the specification of 2Mel and 3cm could be put into cultivation.

2. Medium-term bait fish: 20-300000 fry such as soil dace, wheat dace and Tai dace are mixed in four domestic fish ponds, and silver carp, bighead carp and crucian carp fry can also be cultivated in special ponds as bait fish for large size sweet-scented osmanthus fish.

3. Late-stage bait fish: in addition to self-production and self-sufficiency, you can also purchase. In the later period of culture, dace fish generally enter winter, and dace bait fish are easy to freeze to death. Some cold food species, such as silver carp, bighead carp and crucian carp, should be cultivated to survive the winter, which can be used as backup bait fish for sweet-scented osmanthus fish in winter and spring.

Living environment of mandarin fish

Mandarin fish are bottom fishes, living in still water and rivers, lakes and reservoirs with certain flowing water, especially in shallow lakes with abundant water plants. It generally lurks at the bottom of the water during the day, looks for food everywhere at night, has the habit of burrowing, and does not like to live in groups. The suitable water temperature for life is 15-32 ℃, and it is inactive and feeding when the water temperature is below 7 ℃.

Through the above content, I believe everyone has a certain understanding of the culture technology of mandarin fish. Although breeding mandarin fish seems to have broad prospects and excellent economic benefits, we should not blindly follow suit. After all, starting a business is risky.
