How to raise mandarin fish? Why so few people raise mandarin fish

Mother's upbringing, this is a matter of nature. You can't interfere.

The fish tank is 80cm*36cm, and the bottom filter (the physical filter box of the bottom filter can raise a little small river shrimp and eat sundries).

Mandarin fish is caught by fishermen in the Gan River who bought it in the vegetable market.

2.Do not lay bottom sand (fish droppings do not hide in the bottom sand).

3.You can plant some aquatic plants (my aquatic plants are to use a flashlight drill to punch holes in the sunken wood, and insert the aquatic weeds into the sunken wood, and it will take root on its own).

4.My fish tank has a heating rod, the water temperature has been maintained at about 24 degrees, I personally feel that the mandarin fish reacts very much to the temperature difference, if your fish tank also has a heating rod, it is recommended that the temperature of the water to change the water is not too different from the temperature of the fish tank. Personally, I suggest that the southern region can do without a heating rod.

5.The filtration system is strong words, plus there are water plants. I recommend that I try not to change the water if I can change the water (I changed the water once and hung 4 strips).

6.Forage fish must not be mixed with mandarin fish, and only mandarin fish can be found in the tank.

7.The density should be stocked according to the size of their own fish tank, and the mandarin fish will fight for hiding places, and if the density is too large, there will be fights.

8.Do not put river shrimp in the fish tank, river shrimp eat fins.

9.My forage fish are usually fed with wheat ear fish and small loaches (kept in fry isolation boxes).

I don't know if my summary is right or not (it's all a bloody lesson in exchange for the lives of several mandarin fish), and I hope to correct it if there is something wrong. Mandarin fish in fish tanks should pay special attention to heating, usually the water temperature should be controlled at about 24, so that the fish can grow healthily. In addition, the bottom of the fish tank should not be covered with sand, it is better to put a sunken wood in it, but the sharp part should be removed to avoid causing harm to the fish.

And also pay attention to filtration, the stronger the filtration system, the more stable the water quality, the more guaranteed the health of the fish.

1. There needs to be a certain amount of water flow, mandarin fish mainly live in areas where rivers are relatively slow, and if they live in stagnant water, it is likely to cause them to die;

2. Water source conditions, mandarin fish are very strict about water source conditions, and water quality and water temperature need to be strictly controlled;

3. Food, mandarin fish is a carnivorous fish, and the feeding should be based on meat food. The water temperature suitable for life is between 20-30 degrees, and the lowest temperature they can withstand is 7 degrees, so the water temperature can not be lower than 7 degrees.

Mandarin fish naturally like to hide, and when rearing, a sunken wood can be placed in the fish tank to meet the growth needs of mandarin fish. The density should not be too large when feeding, as too much density will lead to the phenomenon of mandarin fish fighting. When feeding, you can also feed it some chopped small fish, small shrimp and aquatic insects so that the mandarin fish can better digest and absorb nutrients.

Mandarin fish like to hide by nature, and a sunken wood can be placed in the fish tank to meet the growth needs of mandarin fish. You can also insert some algae on the sunken wood to achieve the landscaping effect.

When raising mandarin fish, the feeding density should not be too large, as too large density will lead to the phenomenon of mandarin fish fighting. When changing the water, you can change one-fifth of the water in the fish tank each time, and you need to add some new water to the tank every day.

When feeding, feed the mandarin fish some small fish, shrimp, and various aquatic insects. Before feeding, the feed can be cut into small pieces before feeding, so that the mandarin fish can better digest and absorb nutrients.

<> mandarin fish. It is a carnivorous fish, it only eats live fish, and the cost of raising is higher than that of trembling grip chong, so few people raise it. This fish is more widely distributed in China than leather stools, and is found in rivers, lakes and reservoirs, and will lurk under the water during the day and forage at night.

It is suitable for living in water of 18-30 days, usually every 7-10 days, and can be shortened in summer, once every 5-7 days.

Mandarin fish can be raised in cold water. Mandarin fish is a completely freshwater fish that likes to inhabit aquatic plants such as rivers, lakes, and reservoirs.

In the dense and clean water body, it generally lurks at the bottom of the water during the day and moves around at night to feed. The suitable water temperature for life is 15 32, so cold water can be used to raise mandarin fish.

Daily management methods of mandarin fish:1. Patrol the pond frequently: find that the mandarin fish swims slowly or dies and check it in time while fishing up to the shore, observe whether the bait fish is sufficient, whether the mandarin fish chasing the fish is normal, and learn to see the feces of the mandarin fish, the feces are loose and the end is yellow, and there may be enteritis.

Finally, it is necessary to take anti-theft measures, etc.

2. Oxygenation: dissolved oxygen limits production, polyoxygen must be prolific, and at the same time it is necessary to increase oxygen, it is recommended to open the aerator on rainy days, at night, and add fish larvae on the same day.

You don't need to open it during the day.

3. Water quality management: ammonia nitrogen, hydrogen sulfide and nitrite in the pond.

The pH value needs to be tested on a regular basis, and the water quality should be controlled regularly with biological agents.

The optimal temperature for mandarin fish to grow and feed is 23 to 28 degrees Celsius, and the optimal water temperature for breeding is 21 degrees Celsius. Mandarin fish usually come out to feed at night and rest underwater during the day. Finally, the fish pond should have a certain amount of flowing water, can not be stagnant water, such a breeding site is not very suitable for breeding mandarin fish, if it will be slightly mismanaged water quality, it will cause a large area of death, the loss is relatively large.

The optimal water temperature for mandarin fish farming is 23 to 28 degrees Celsius, and the optimal water temperature for breeding is around 21 degrees Celsius.

1. In order to ensure the survival rate of mandarin fish breeding, it is required that the stocking specifications must be more than 3 cm, and generally about 1000-1500 mandarin fish fingerlings of 3-4 cm per mu are stocked.

2. Bait fish cultivation in the same pond: the early bait fish cultivation can be carried out 15 to 20 days before the stocking of mandarin fish fingerlings. Generally, 50 800,000 pieces of bream, grass carp, silver carp and bighead carp are put into the coarse return beam per mu for mandarin fish to feed in the early stage.

At the same time, in order to reduce the cost of forage fish, some fast-reproducing bait fish parents can be mixed in the mandarin fish pond, such as 200 400 pairs of tilapia per mu or 500 2-year-old crucian carp, and the offspring of rock transportation can be used as live bait fish for mandarin fish to feed. Of course, it is also possible to divide the pond into two parts with a moderate size of thin nets, and raise the bait fish parents while raising mandarin fish, so that the juveniles that reproduce can pass through the thin nets and become bait for the mandarin fish.

3. Feeding of bait fish cultivated in special pools: In the high water temperature and rapid growth period of mandarin fish, when the bait fish in the mandarin fish cultivation pond is insufficient, you can supplement feeding the bait fish cultivated in the special pool every day, of course, the feeding amount is based on the principle of maintaining a certain density of bait fish in the water body and increasing the predation opportunity of mandarin fish. The size of the forage fish is 30% to 59% of the body length of the mandarin fish, and the feeding and growth of the mandarin fish and the individual differences of the mandarin fish should be checked frequently.

In the bait fish, it is necessary to match the appropriate amount of bait fish of different sizes to ensure that the mandarin fish of different sizes have sufficient and palatable bait. It is important to note that the bait fish must be disinfected first.

4. Water quality control: Because of the high stocking density and large amount of bait in the mandarin fish breeding pond, the residual bait and a large amount of feces have a great impact on the water quality of the pond. Therefore, in addition to requiring a good pond inlet and drainage system, regular replacement of pond water, and keeping the minimum dissolved oxygen of the water body at more than 4 milliliters during the whole feeding process, it is also necessary to equip the mandarin fish breeding tank with an aerator.

The start-up time of the aerator needs to be determined according to the specific situation, and at the same time, lime water should be regularly sprinkled to regulate the water quality, and other management measures are basically the same as those of domestic fish farming.
