The latest Culture techniques of Pelteobagrus fulvidraco

Pelteobagrus fulvidraco is a common species in rural ponds. Some people may find that its name is different from the name we usually read. That's right, because Xiaobian is from Hunan, pronounced as Huanggu fish here in Hunan, and Wang Jiao in Zhejiang. It actually refers to Pelteobagrus fulvidraco. This kind of fish has spiny beard hair on its body. When the editor went fishing when he was young, he dared not touch it with his hands. Most people were fishing. Then Shuai Shuai will tell you how to raise Huanggu fish by yourself.

I. Pond conditions

The requirement for the pond is not high, everyone who has fished knows that some yellow mud ponds can catch yellow fish, so the area of the pond can be large or small, depending on everyone's breeding quantity and density, the water in the pond had better have a depth of one and a half meters, if the bottom of the pond is too thick, and the bottom had better be mixed with sediment as the bottom of the pond, the pond should have a drain and irrigation mouth. There may not be, but there must be an outlet, and then the amount of water must be sufficient. The whole pond must be carried out for two weeks before the fish is released, and the fish pond must be cleaned up and the water quality must be disinfected. Sprinkling quicklime and bleach in the pond can carry out a preliminary treatment of the water quality, and can play a role in eliminating some pathogens and microorganisms in the water.

2. Stocking of seedlings

Fish fry should be released in advance, so that the growth and development time of yellow croaker can be extended to the maximum extent. It is best before mid-June that fry without disease and damage should be selected to ensure the overall survival rate of fry. 120000 to 150000 fry per mu can be stocked per hectare.

III. Culture management

1. When it was fed some time ago, its main food source was to hunt small organisms and zooplankton in the pond, and when it was not enough to meet the growth needs of yellow fish, it could be fed artificially, and some fresh bait could be prepared twice a day. And we also need to allocate and control the amount of food to be fed, generally twice as much food in the afternoon as in the morning, and miscellaneous fish can be fed after a week. In order to improve nutritional quality, you can also add some foods rich in protein and other nutrients to feed together. When the seedlings grow to five centimeters, you have to match some corn, cauliflower and other plants and vegetables in the feed.

2. Make an inspection every morning and evening to check the water quality, fish fry and food intake, clean up the excess and remaining bait, and then change the water according to the pollution and transparency of the water. generally, there is no special case is to change the water once a fortnight or so, and then use quicklime or bleach for disinfection.

3. It is necessary to prepare for overwintering at the end of autumn, and when the water temperature drops below 10 degrees after winter, it is necessary to do a good job of heat preservation, and at the same time disinfect the water quality in the pond. Bleach is also used for disinfection, and measures should be taken to sweep snow, replenish water and prevent diseases around the pond during the winter.

Fourth, yellow croaker disease

Diseases mainly occur most frequently in July and August in summer, so we can sterilize the water every month and feed once every half a month. When spraying, we should avoid the effects of pests such as copper sulfate and trichlorfon. Throwing bleach every two weeks can inhibit the disease, once infected, and then sent to the hospital.

The above is the latest culture technology of Pelteobagrus fulvidraco. You can build a pond next to your home or use other ponds for breeding, which can be eaten by yourself or sold in the market.
