Habits and culture of Pelteobagrus fulvidraco

1. living habits

Yellow catfish, commonly known as yellow bone fish. It is a freshwater bottom fish. It likes to inhabit the bottom of the water during the day and is not often active. It swims to the middle and upper layers of the water body at night to feed. The culture of Pelteobagrus fulvidraco requires light water quality, high dissolved oxygen and suitable temperature of 0~38℃. Pelteobagrus fulvidraco is a kind of mild carnivorous fish. It likes to eat small fish, shrimp, snail meat and artificial feed.

2. larval rearing

Each mu (1 mu =667 square meters) seedling amount of 10~12 million tail, can be fertilized under the pond, culture biological bait, can also sprinkle soy milk, peanut cake or egg yolk. Cultured to 3~4 cm in size, then cultured in ponds, 30 ~ 40 thousand fish per mu, and cultured to 6~8 cm in size, then entered the stocking stage.

3. Adult fish culture

(1) The suitable area of pond for main culture is 3~8 mu, the water depth is 1.2~1.5 meters, 5000~10000 yellow catfish fry are stocked in each mu of water surface, and the commercial fish weighing 75~100 grams can be cultivated in the same year.

(2) 500~1000 Pelteobagrus fulvidraco fry per mu of water surface can be interbred in pond, and 35~60 kg commercial fish can be produced.

(3) Cage breeding can stock about 500 larvae of Pelteobagrus fulvidraco per square meter, and commercial fish can be cultivated in the same year.
