Key points of garfish breeding technology

The catfish, scientifically known as Pelteobagrus fulvidraco , also known as yellow bone fish and yellow croaker, is a common freshwater fish. Its meat is tender, with few bones and high fat, and has high nutritional value. It is a delicacy on the table and has broad prospects for breeding. So what are the key points of garfish farming technology ? Let’s learn more about it below.

1. Pond conditions

The pond area for breeding yellow catfish is not strict and can be large or small, but the water depth should be kept above 1.5 meters. The silt at the bottom of the pond should not be too thick, and a sandy bottom is preferred. The pond requires convenient drainage and irrigation and sufficient water. Before stocking the fish pond, use quicklime to disinfect the pond. Use 75-90 kg of quicklime per acre of pond to completely remove wild fish and kill pathogens.

2. Stocking density

Generally, the best time to stock the pond with fry is when the water color in the pond is formed and the reproduction of rotifers reaches its peak. In ponds mainly for breeding yellow catfish, 20,000 to 30,000 yellow catfish fingerlings with a total length of 3cm-5cm can usually be stocked per mu, and appropriate amounts of grass carp, silver carp, bighead carp and other fish species can be mixed.

3. Feeding

When feeding, you must master the "four fixed" principles. Generally, the daily amount of feed is 5-6% of the fish body weight. 2-3 feeding tables are set up in the pond, and the feeding tables are set 10-20 cm from the bottom of the pond. Feed formula reference: fish meal 23%, silkworm pupa meal 8%, bone meal 8%, blood meal 8%, yeast powder 6%, soybean powder 17%, wheat bran 23%, vegetable oil 3%, multivitamin 1%, salt 1.5%, adhesive 1.5%.

4. Daily management

You should patrol the pond every day, pay attention to the water color and the feeding and activity conditions of the fish, and keep the water fresh, with sufficient dissolved oxygen and rich bait organisms through measures such as water injection, use of microbial agents , spraying of fertilizers and turning on aerators. At regular intervals, the pond should be disinfected and sterilized, and immune preparations such as vitamin C should be added to the feed to improve the disease resistance of the fry and prevent the occurrence of fish diseases.

5. Disease prevention and treatment

Yellow catfish has a strong disease resistance. As long as the water quality is strictly controlled according to requirements and routine disinfection and prevention are carried out, diseases rarely occur. Therefore, the focus is on prevention, and because yellow catfish is a scaleless fish and has poor tolerance to drugs, even if it becomes ill, effective and mild drugs should be used as much as possible during treatment.

In general, although garfish is one of the important freshwater economic fish in my country, its breeding technology threshold and environmental requirements are relatively high. Therefore, everyone should not blindly follow the trend of breeding. The most important thing is to master the relevant breeding techniques first.
