Four Important Methods for Raising Catfish

Catfish mostly live in freshwater ponds and rivers, with some species in saltwater. They are easy to farm due to their low water quality requirements, fast growth, broad diet, and low disease incidence. Here are some catfish farming techniques:

1.Selecting High-Quality Fry Water Quality Management

After disinfecting the fish pond, fertilize the water for a week. Plant water hyacinths to regulate water quality. Change 1/3 of the pond water every 10-15 days. Maintain water quality, ideally yellow-green. If fry rise to the surface, it indicates oxygen deficiency; promptly add new water and install aerators possible.Stocking Fry: Introduce fry after rotifers appear in the pond. Use fry larger than 3 cm, disinfect them in a salt solution (1 kg salt in 30 kg water for 5 minutes). Stock on sunny days, with 6000-10000 fry per mu. Add new water every 2-3 days and apply fertilizers.

2.Scientific Feeding Initial feed

Hatchlings rely on their yolk sacs for nutrient intake, and after 2 days they begin to ingest hard-boiled egg yolk or small zooplankton.Growth feed: feed water fleas, mosquito larvae, small fry. Gradually introduce artificial feed with protein content above 45%.Feeding principle: regular and quantitative feeding, twice a day, the daily feeding amount of 5% of the weight of the fish. First in the small pool of intensive fish fry, and then transferred to the large pool, to prevent waste and pollution of water quality.

3.Strengthen culture management Breeding season

The breeding season is from March to May. Select mature female and male fish. The female fish has an expanded and soft abdomen, and the male fish has an elongated body with small and narrow reproductive holes. Adopt dry induction method for egg collection.Translated with DeepL.com (free version)Fertilization: Mix collected eggs with sperm suspension, wash away excess sperm, and spread fertilized eggs on mesh materials like window screens.

4.Enhancing Disease Prevention Viral Fin Rot

 Use 10,000 units of bleaching powder solution for the entire pond.Parasitic Diseases: Use 4,000 units of crystal trichlorfon or 6,000-7,000 units of a copper sulfate and ferrous sulfate mixture (5:2 ratio) for the entire pond.Enteritis: Avoid feeding moldy feed. Add 0.05%-0.1% fresh garlic juice to the feed, and 20-100 grams of oxytetracycline per 100 kg of feed for 5-7 days.Black Body Disease: Maintain clean water quality and avoid unfermented fertilizers. Use gallnut (2-4 grams per cubic meter) and quicklime water (30 grams per liter) for the entire pond, every other day for 2-3 treatments.Gas Bubble Disease: If fish float belly-up due to gas bubbles, replace the pond water promptly and provide adequate live feed. Use 1.5-2 kg of salt per meter of water depth for the entire pond.
