Detailed Explanation of the Latest Aquaculture Technology Points for Yellow Catfish

The yellow catfish is a very common fish species in rural ponds. Some people may find that its name differs from what we usually call it. That's right, because the editor is from Hunan, here in Hunan it is called "Huanggu fish," and in Zhejiang it is called "Wangjiao." Actually, they all refer to the yellow catfish. This fish has whisker-like barbels on its body that look like spines. When I went fishing as a child, I didn't dare touch it with my hands. Most people catch them by fishing. So now let Shuaishuai tell everyone how to raise Huanggu fish yourself!

I. Pond Conditions

The requirements for the pond are not high. Anyone who has gone fishing knows that yellow catfish can be caught even in some yellow mud ponds, so the pond area can be large or small, depending on your breeding quantity and stocking density. The pond water should ideally be one and a half meters deep. If the mud at the bottom of the pond has accumulated too thickly, that won't work either. It is best to use a pond with a bottom base of mixed mud and sand. The pond should have a drainage outlet and a water inlet, or it can do without them, but a drainage outlet is a must. Then the water volume must be sufficient. Before stocking the fish fry, the pond must be prepared for two weeks. First clean the fish pond thoroughly, disinfect the water quality, and spread quicklime and bleaching powder in the pond to carry out a preliminary treatment of the water quality. This can play a role in eliminating some pathogens and microorganisms in the water.

II. Fry Stocking

The fry should be stocked in advance, as this can maximize the time for the yellow catfish to grow and develop. It is best to do this before mid-June. The stocked fry should be selected as those free of disease and injury to ensure the overall survival rate of the fry. Twelve to fifteen thousand fish per mu, or 120,000 to 150,000 per hectare, can be stocked.

III. Aquaculture Management

1. During the earlier period of feeding, their main food source still relies on preying on small organisms and zooplankton in the pond. When these are no longer enough to meet the growth needs of the yellow catfish, artificial feeding can begin. You can prepare some live bait to feed them, twice a day. You must also allocate and control the feeding amount well. Generally, the amount fed in the afternoon should be twice that fed in the morning. After a week, you can feed them minced fish meat. To improve nutritional quality, you can also add some foods rich in protein and other nutrients and mix them together for feeding. When the fry grow to five cm, you should add some corn and cauliflower and other plant vegetables to the feed.

2. Inspect once every morning and evening to check the water quality, the fry, and the feeding situation. Clean up excess and leftover bait thoroughly, then change the water according to the pollution level and transparency of the water. Generally, under normal circumstances, change the water about once every two weeks, then use quicklime or bleaching powder for disinfection.

3. At the end of autumn, preparations for overwintering should begin. After winter arrives, the water temperature will drop below ten degrees, so insulation work must be done well. At the same time, disinfect the water quality in the pond, also using bleaching powder for disinfection. During the overwintering period, measures such as clearing snow around the pond, replenishing water, and preventing disease must be carried out well.

IV. Yellow Catfish Diseases

Diseases mainly break out most often and most frequently in July and August of summer, so we can sterilize and disinfect the water every month, and feed once every half month. When spraying medicine, avoid the effects of pests such as copper sulfate and trichlorfon. Spraying bleaching powder once every two weeks can play a role in suppressing the disease. Once infected, you can do this, then send it to the hospital.

The above is the latest aquaculture technology for yellow catfish. You can build a pond next to your home or use other ponds for breeding. It can be for your own consumption or for market sales. Either way, you profit. If you want to learn more related knowledge, please continue to follow Qinnong Network!
