Detailed Explanation of Yellow Catfish Feed Formula and Raw Material Ratios

Yellow catfish are distributed across major freshwater waters throughout the country, especially in the rivers and lakes of the middle and lower reaches of the Yangtze River. Their flesh is tender with no intermuscular bones, and they taste delicious and are rich in nutrients, with tonic effects and medicinal value. So when farming yellow catfish, what should the fish feed formula be? Friends who do not know may wish to take a look together.

I. Yellow Catfish Feed Formula

Yellow catfish have relatively high requirements for protein in the bait and for bait quality. When feeding a complete compound feed, the feed is required to have a protein content of 35%-45% and crude fat of 5%-8%. The artificial compound feed may use the following formula: fish meal 30%-40%, soybean cake 20-30%, rapeseed cake 10%-35%, wheat middlings 15%-18%, rice bran 10%-15%, feeding attractant and growth-promoting additive 2%-5%.

II. Pond Conditions for Farming Yellow Catfish

Yellow catfish are warm-water fish that grow in the bottom layer of water bodies. Their survival temperature is 6-38°C, the most suitable growth temperature is 25-28°C, the pH range is 6.0-9.0, and their tolerance to low oxygen is slightly worse than that of conventional fish. Therefore, ponds for farming yellow catfish should meet the following conditions.

1. Suitable water depth

The water body must have a certain depth and must reach more than 2 m. If the water depth is insufficient and the light is too strong, it is not suitable for the living habit of yellow catfish, which prefer to feed under weak light.

2. Sufficient water source

The pond must have a stable, sufficient, and pollution-free natural water source, and it is required to have a high-quality water supply in all four seasons of the year.

3. Capable of drainage and irrigation

The pond is required to have a complete inlet and drainage system, with smooth drainage and irrigation, safe and reliable water inlet and outlet, and supporting construction of fish-blocking facilities such as nets.

4. Good bottom substrate

The pond bottom is required to be flat to facilitate fish harvesting. Sandy soil is best for the pond bottom substrate, and the bottom silt should be controlled at about 10 cm. The pond bottom must have good water retention and fertilizer retention, and be easy to fertilize.

5. Good water quality

The water quality is required to meet aquaculture water standards. Yellow catfish like clear and clean water quality. The pond water transparency should be maintained above 35 cm, and the water body should preferably have flowing live water year-round. The pond area should be suitable, and it should be equipped with mechanical equipment such as aerators, water pumps, feeding machines, and aquaculture boats.
