What food does mandarin fish eat and what should be paid attention to in breeding

Mandarin fish can eat live fish and live shrimp, such as small crucian carp and small white stripe. Newly born mandarin fish can eat the seedlings of other kinds of fish. The breeding pond should be located near the water source, with good drainage and irrigation, and good water quality. The area of ​​the breeding pond should be sufficient, and small fish such as white crucian carp should be prepared as feed. The water quality should be clean and transparent, and the transparency should be greater than 40cm.

1. What foods should Mandarin fish eat?

The food that Mandarin fish eats is live fish and live shrimp. Newly born Mandarin fish can eat the seedlings of other kinds of fish. When breeding Mandarin fish artificially, they can be fed with small crucian carp and small white stripes.

2. What should we pay attention to in breeding?

1. Breeding pond

The breeding of mandarin fish is inseparable from the breeding pond. The site selection of the breeding pond should take into account many factors. It should be close to the water source, with convenient drainage and irrigation, and good water quality. The area of ​​the breeding pond should be sufficient, and the most suitable area is between 3-8 mu. The depth of the water in the breeding pond should be sufficient. Mandarin fish likes to live in water areas, and the depth of the water in the breeding pond should not be less than 1.5m. In winter, in order to help mandarin fish survive the winter, the depth of the water can be appropriately increased.

2. Feed

When breeding mandarin fish, there must be enough food. Mandarin fish is carnivorous, so you can prepare some small fish for it, such as white crucian carp. Feed fish for mandarin fish can be cultivated at the same time as mandarin fish to ensure sufficient feed.

3. Water quality

The water quality for breeding mandarin fish should be clean and the transparency of water should be greater than 40cm. If the water quality of the breeding pond is too poor, it will easily make mandarin fish sick. The water in the pond should be changed once every 7 days.

Mandarin fish, also known as Guiyu and Jihua fish, belongs to the order Perciformes and the genus Siniperca. It is widely distributed and breeds in major rivers and freshwater lakes. Mandarin fish has tender meat, few bones, delicious taste and rich nutrition. It is a delicacy on banquets and is favored by consumers. Not only can a small amount of mandarin fish be mixed in ponds to remove wild fish, but it can also be raised in special ponds. It is one of the popular species in freshwater aquaculture.

1. Living habits

Mandarin fish is a typical carnivorous fish. When artificially fed, it can be fed dead fish, dead shrimp, etc. Male fish mature at the age of three, and female fish mature at the age of four. Its growth rate is relatively fast, reaching 50-100 grams in the first year, about 0.5 kilograms in the second year, and 1-1.5 kilograms in the third year.

2. Pond conditions

The pond for breeding adult mandarin fish should be 3 to 8 mu in area, with a water depth of more than 1.5 meters, and about 2.5 meters in summer. The bottom should preferably be sandy loam with less humus, sufficient water source, fresh water quality, and preferably flowing water. The dissolved oxygen content of the pond water should be more than 5 mg/L, the pH value should be 7 to 8, and the transparency should be more than 30 cm.

3. Bait fish cultivation

The area for bait fish breeding is 3 to 4 times that of the mandarin fish pond. Considering the palatability and economics of mandarin fish, bait fish are generally selected from silver carp, crucian carp and other species, and the stocking density is 300,000 to 500,000 fry per mu. After the fry are released, they do not need to be fed immediately. When the number of zooplankton decreases and the fry are foraging around the pond, they can be fed with soy milk or other feed. In the early stage of breeding, feed is added when it is eaten up, and in the later stage, the size of bait fish should be controlled, and the length of bait fish should be controlled between 1/2 and 1/3 of the body length of mandarin fish.

Generally, when stocking 8 to 10 cm long mandarin fish, the size of bait fish should be controlled at 3 to 4 cm.

4. Stocking of Mandarin Fish

When raising mandarin fish alone, 800 to 1,000 mandarin fish of 8 to 10 cm in size can be placed per mu. Some fast-breeding fish can also be mixed in the mandarin fish pond as live feed. Generally, 200 to 400 pairs of tilapia broodstock or 60 two-winter crucian carp are placed per mu. Use a sparse net to divide the fish pond into two halves, and raise mandarin fish on one side.

Fish are raised while other fish are raised, so that the young fish can pass through the sparse net and become food for the mandarin fish. At the same time, the activities of the mandarin fish do not hinder the quiet reproduction of other fish.

5. Feeding and Management

1. Feeding: Feed fish at intervals. In the early and late stages of breeding, feed once every 7 to 10 days, and in the middle stage, feed once every 5 days or so. The ratio of mandarin fish to bait fish should be maintained at 1:5 to 10. Too few bait fish will affect the feeding and growth of mandarin fish, while too many bait fish will easily cause lack of oxygen and floating, which is not good for the growth of mandarin fish.

2. Water quality management:

It is necessary to frequently add new water, especially from June to September, add new water every 5 to 7 days, 15 to 20 cm each time, to keep the water rich, active, fresh and tender, and promote the healthy growth of mandarin fish. Submerged plants such as Vallisneria and Hydrilla verticillata can be planted around the pond to provide a hiding place for fish and purify the water quality. Sprinkle quicklime water once every 15 to 20 days, 15 to 20 kg each time. Open the aerator in a timely and reasonable manner to increase the dissolved oxygen content in the pond water to prevent fish from lacking oxygen. At the same time, some oxygenators should be prepared to rescue fish when they float to the surface due to lack of oxygen.
