How to culture channel catfish with channel catfish

Pond: the water depth should be 1.5-2 meters, the water supply is sufficient, and the water quality is not polluted. Management: keep the water quality fresh during the feeding period and change the water every 10-15 days (the amount of water change is 1pm 3-1pm 2). Feed: artificial feed. Spawning: the spawning temperature range of channel catfish is 21-29 °C, the optimum temperature is 26 °C, and the breeding season is from June to July. Diseases: common diseases are Edwardsilosis, columnar disease and so on, which need to be prevented and treated actively.

Channel catfish is a kind of large fish, like these precious fish, we should protect them well, but how do we raise them? The editor doesn't know how to raise channel catfish. I've only eaten it and never raised it. Now let the editor introduce to you how to raise channel catfish. Let's learn it together.

How to raise channel catfish

1. To keep the spotted forktail in the pond, we should ensure adequate water supply, fresh water and water quality, and the water quality will not be polluted. The water depth is 1.5-2 meters and the area is 0.2-0.3 hectares. After clearing the pond, 800-1500 fish with a length of 7-12cm are released every 0.07ha in spring.

2. There are 10 carps 20-23 cm long and 10 carps 13-16 cm long to regulate the water quality. During the feeding period, the water quality should be kept fresh, and the water should be changed every 10-15 days (the amount of water is 1pm 3-1pm 2) and fed with artificial feed. Channel catfish culture is not difficult, can be bought to breed oh.

Culture technique of channel catfish (channel catfish)

The main results are as follows: 1. Usually, the spawning temperature range of channel catfish is 21-29 °C, and the optimum temperature is 26 °C. the water temperature exceeding 30 ℃ is not conducive to the embryonic development of fertilized eggs and the survival of fish fry. The breeding season of channel catfish in the Yangtze River basin is from June to July, and the body weight (or age) is higher than that in the spawning season.

2. When spawning, each fish usually wraps the other head with its caudal fin. The males tremble violently and excrete semen, while the females begin to lay eggs. After fertilization, the eggs stick to each other and attach to the bottom of the pool. All ponds where the four major domestic fish are raised can be mixed with spotted forktail, but it is best to choose a clearer pond.

Prevention and treatment of channel catfish disease

1. The pathogen of Edwardsiasis: Edwardsiella disease is a disease in which the initial diseased fish have injuries of 3 to 5 mm in diameter on the side of the pectoral fin, such as needle-like trauma, and deep into the muscles. Within 10-15 days, the damage area gradually expanded, bacteria frequently invaded the blood of diseased fish or infected kidneys, and sick adult fish had foul-smelling gases in the injured muscles. Dead fish are obviously related to kidney and liver dysfunction.

2. The pathogen of columnar disease: in the early stage, the head of the diseased fish showed injury, or the fin had gray spots and slight congestion. When the symptoms expand, they become gray-white ulcers. The skin is completely eroded and the muscles are exposed. As the infection deepens, the fish die.

3. After the fin of the infected fish is corroded, the pathogen spreads to other parts of the body. Usually there is brown necrotic tissue at the end of the Gill filament and develops to the base of the Gill filament. Fungi can be used as secondary pathogens to invade these lesions. Every animal has diseases, and fish is a food we often eat, so it is more preventative.

After reading the above introduction, I wonder if you have learned how to raise channel catfish. The editor thinks it's easy to raise and easy to operate, don't you think? But if you want channel catfish to reproduce and grow, there must be some other ways to take the time to learn. I don't know if the editor's information has helped you.
