Artificial culture methods of mandarin fish

The nutritional value of mandarin fish is very high, and we may not be familiar with the term mandarin fish. In other words, it is what we often call Mandarin Fish and sweet-scented osmanthus fish. Sales in the market are also quite good. Many people like to eat mandarin fish, and the economic benefits are also good, so many people ask the editor how mandarin fish can be cultured better. So today, let's follow the pro-agricultural network to learn the artificial culture techniques of mandarin fish.

1. Pond construction

Mandarin fish certainly need to prepare the pond, if there is a ready-made pond, then there is no need to dig, just need to clean up the sundries around the pond, then dig up the riverbed of the pond, and then dig out the silt accumulated in the pond. finally, sprinkle a layer of lime into the pond for disinfection, about ten and a half months later, then we can inject new water into the pond. At the same time, we also need to apply an appropriate amount of organic fertilizer to the pond, which can ensure the fertility of the pond, provide some food for the mandarin fish to a certain extent, and maintain the water quality needed for the mandarin fish to survive.

2. Fish fry selection

The selection of mandarin fry determines the survival rate and quality of mandarin fish, so we must choose high-quality fry, so how should we choose it? the editor will teach you a little trick. First of all, we have to make sure that the fry of the same batch of fish we choose are basically the same size. Secondly, we cannot choose which fry that are lazy and inactive, and then we have to see whether the fish's tail is strong or not. A strong one is a good fry. In addition, the mandarin fish fry should look relatively clean and have no scars, so it is almost enough.

3. Stocking density

The density of mandarin fish is also a basic condition for the survival rate of mandarin fish. Generally speaking, friends who have just begun to breed can choose to breed only about 1000 fish per mu, because the culture technology is not mature, if a large number of mandarin fish are raised at a time, it is impossible to manage it at all, and it will cause a large number of casualties, so it is best to have a thousand fish until you have some culture experience in the later stage. When everything is relatively good, such as equipment, you can increase the number of farming. About 1500 to 1800 tails can be raised per mu, and the maximum amount of breeding per mu can only be about 1800. If you want more, you can only expand the area of farming.

4. Feed management

Mandarin fish is mainly fed by catching small fish and shrimps in the water, followed by plankton in the water, and finally some feed prepared according to the formula. So we need to put a batch of other fish with fast reproductive ability in the pond to provide food for mandarin fish, such as crucian carp and carp, so as to meet part of the needs of mandarin fish. Secondly, we need to put some purchased bait fish into the pond every four to five days or so. In order to fully meet the needs of mandarin fish, it is best for bait fish to have time left. Finally, feed is given every ten days or so to promote the growth of mandarin fish.

5. Disease control

Mandarin fish is different from other fish, other fish basically do not have any diseases, and there are a large number of bacteria and parasites in its whole growth process, which will affect the growth of mandarin fish, so we should pay great attention to it. secondly, because mandarin fish mainly eat live fish and shrimp, the medicine used for them does not have much effect on them. So we can only solve these diseases from the source, such as regular cleaning of the pond, removal of suspicious impurities, followed by regular replacement of the water in the pond to ensure water quality, and regular disinfection and sterilization.
