CATDOLL : CATDOLL: More and more people are farming live mandarin fish. What are the things to pay attention to when farming live mandarin fish?

1. More and more live mandarin fish are being farmed. What are the precautions for farming live mandarin fish?

Live mandarin fish farming is increasing, and there are many things to note when farming live mandarin fish. Mandarin fish is a carnivorous fish. Young mandarin fish like to eat small fish and shrimps, and adult fish like to eat fish. In winter, they will reduce or even stop foraging. The water temperature for mandarin fish to grow is 18~30℃, and the most suitable temperature is 23~28℃.

Within this temperature range, as the water temperature rises, the food intake increases and the growth rate also accelerates. Choose a newly opened pond that is leeward and sunny, with loam bottom and less or no silt, and stock 800 to 1,000 mandarin fish per mu. Feed bait fish every 3 to 5 days, and add new water frequently to keep the water level in the fish pond relatively stable.

Choose a fish pond with a good foundation, the water quality is generally good. It is better to have about ten centimeters of silt at the bottom of the fish pond. It is best to have sandy soil with strong water purification ability. The cultivated water quality is relatively stable and has a certain degree of fertility. Ponds with turbid or unstable water quality are not recommended for raising mandarin fish. Feed fish are generally crucian carp fry. Around April 15, put the fish nest (float) with crucian carp eggs into the pond for hatching. The density of fry is generally controlled at about 500,000 per mu. The fish eggs can be put in 2-3 batches, with one day between each batch, such as 1-3-5.

Even if the protein content in earthworms can meet the growth needs of fish, other nutrients will not be able to keep up. If the protein content is high due to nutritional imbalance, the fish will not achieve the desired effect after eating it. On the other hand, it is a waste of protein. It should be put into the mandarin fish pond with some small fish and shrimps, and let the mandarin fish catch them by themselves. Then build a few ponds to breed small fish and shrimps for the mandarin fish to eat. Of course, it is okay to occasionally throw in some earthworms, maggots or silkworm pupae. It is too cost-effective to raise mandarin fish exclusively with earthworms.

This method is suitable for farmers and urban residents. It utilizes the open space in front of and behind houses, in courtyards, as well as old containers, brick pools, seedling hotbeds, etc. to produce animal protein waste feed, process organic fertilizers, and treat domestic waste.

2. Is it easy to raise mandarin fish as an ornamental fish? What should you pay special attention to when raising mandarin fish?

1. Mandarin fish can be raised as ornamental fish, but when breeding, you must use a large fish tank with a depth of more than 1 meter.

2. They are carnivorous fish and have a large appetite. When breeding, they should be fed every day.

3. Food can be other small fish or small shrimps.

4. They have high requirements for water quality and need to change the water every 3-4 days to ensure good water quality.

5. In addition, they also have certain requirements for water temperature. It is best to control the water temperature at around 20℃ during breeding.

3. The latest technology of mandarin fish farming

The latest technology of mandarin fish farming is as follows:

1. Living habits of mandarin fish: bottom fish, living in clean water and rivers, lakes and water conservancy hubs with a certain amount of water flow, especially in shallow lakes with rich aquatic plants. They usually lie in ambush underwater during the day and move around to look for food at night. They have the habit of digging holes to make nests and do not like to live in groups. The water temperature suitable for daily life is 15-32℃. They do not move much and eat when the water temperature is below 7℃.

2. Mandarin fish diet: It is a carnivorous and ferocious fish. After hatching, it prefers to eat fry of other fish species and live bait. When hungry, it will kill each other. At the fingerling stage, it can eat other farmed fish species that are 70-80% of its own length. The size of the bait fish it eats is only based on its size.

The rest

The area of ​​the pond for breeding mandarin fish: the total area should be 4 to 6 mu, at least 1 mu, and no more than 10 mu. If the pond area is too small, the water body will change greatly and it will be difficult to control. If the pond area is too large, the bait fish will be relatively dispersed, which is not conducive to the feeding of mandarin fish. The pond should be downwind and facing the sun, east-west, with a width-to-height ratio of 3:2. The bottom mud should be flat, sandy loam, and the pond should be excavated with less or no sludge.

Supporting production of bait fish: The bait fish in the main breeding pond of mandarin fish can usually feed the mandarin fish for one month. After one month of feeding, the body length of mandarin fish can generally reach 11 to 14 cm.
