Yellow catfish is a high-quality fish species worth recommending
Yellow catfish, also known as jiangsang, gayazi, and angsi fish, has a yellow-green back, yellow flanks with intermittent black patches, a naked scaleless body, and an elongated shape. It is distributed in natural waters in most parts of China. The yellow catfish is a warm-water bottom-dwelling fish that prefers to inhabit still or slow-flowing waters. Its survival temperature is 0°C-38°C, it has extremely strong adaptability, and it has great aquaculture potential, so it can be promoted for farming in most inland waters nationwide. The yellow catfish has tender flesh and a delicious taste. It not only has nourishing effects but also has certain medicinal value, and is deeply favored by consumers. It has traditionally been regarded as a premium fish. Its adult individuals are about 250 grams, which is very suitable for consumption by a family of three in China today. At the same time, yellow catfish also has huge market potential in Japan, South Korea, Southeast Asian countries, and other countries, and is an excellent variety for earning foreign exchange through export. The farming of commercial yellow catfish mainly includes the following three methods: 1. Mainly culturing yellow catfish by feeding fresh small fish and shrimp. Ponds of 2-5 mu are suitable, with an average water depth of 1.8 m. The transparency of the pond water should be controlled at 20-30 cm. Generally, wild fry collected from nature are stocked, with a size of more than 15 grams per fish. If artificially bred fry are stocked, the size is generally 5-8 cm. Then conventionally add some silver carp, bighead carp, grass carp, crucian carp, and others. The stocking density is suitably 500 fish per mu. About 50-250 kg of yellow catfish can be harvested per mu. 2. Mainly culturing yellow catfish by feeding frozen marine fish and freshwater small fish and shrimp. The requirements for ponds and stocking density are similar to those for feeding fresh small fish and shrimp. Set up a feeding point of about 5 square meters at the downwind end of the pond, control the transparency of the pond water at 20-30 cm, and ensure that the dissolved oxygen content of the pond water is above 3 mg/L. About 50-400 kg of yellow catfish can be harvested per mu. 3. Polyculture of yellow catfish with pond-cultured fish. The stocking size is required to be above 10 cm, with 200-300 fish stocked per mu, and the yield of yellow catfish per mu can reach 50-150 kg. The Yinshi Large-Mouth Catfish Breeding Farm in Honghu City, Hubei Province, has accumulated rich experience in artificial breeding and farming of yellow catfish and currently has the capacity for large-scale production of yellow catfish fry.
