Latest market prices:

At present, the market price of catfish is about 8 yuan a catty, but the prices in different regions will be different, so the specific price should be consulted in the local market.

Breeding skills:

fish-releasing

In order to improve the survival rate and culture benefit, the large-mouth catfish seed should be more than 8cm in size and neat in specification, and the stocking density of 8cm-10 cm should be 1000 - 1500 fish per mu; 800 - 1200 fish per mu of 10cm-12cm should be put, and 100 - 120 large-size silver carp and bighead carp species of 150 g-250g should be matched in the pond to adjust the water quality.

bait feeding

Catfish is a carnivorous fish, mainly live fish or frozen fish, animal viscera as bait, but also through artificial domestication ingesting artificial feed.

1. Carnivorous bait: When putting large-mouth catfish species, correspondingly put carp, crucian carp and other species slightly smaller than them, still mainly frozen fish pieces every day, but also feed pig lungs, cattle lungs and other animal organs. When these animal feeds cannot be guaranteed, they can be artificially domesticated and ingested with artificial compound feed, which can receive better results.

Artificial compound feed: The protein content of compound feed is 41%-50%, and (2-4) bait stations are set up in each pool when feeding, so as to facilitate observation of feeding conditions.
