Wild native catfish is a delicacy among fish: market price per jin and differences from catfish and large-mouth catfish

Native catfish, also known as local catfish, is a wild fish that lives in the middle and lower layers of reservoirs, lakes, rivers and ponds. It is popular for its rich nutrition and delicious meat. So how much is the market price of native catfish per jin? What are the differences from catfish and large-mouth catfish?

1. How much is the market price of native catfish per jin?

1. How much is the market price of native (wild) catfish per jin?

(1) According to the latest data, the wholesale price at Wuhan Baishazhou Aquatic Products Market is currently 5.5 yuan/jin for catfish under 1 jin and 6.2 yuan/jin for catfish over 1 jin; the wholesale price is 5.5 yuan/jin for channel catfish under 1 jin and 5.7 yuan/jin for channel catfish over 1 jin.

(2) According to market surveys, the purchase price of catfish in the Northeast is currently about five yuan or more per jin, and the market has recently been relatively stable. The wholesale price in the Wuhan market is not much more than a few mao higher than the purchase price in the Northeast. Adding freight costs, Wuhan wholesalers basically make no money when they bring catfish from the Northeast to sell.

2. About how much profit can be made from farming one mu?

(1) Catfish is a high-density farming industry, with a yield of more than 10,000 jin per mu. That is to say, the net profit of farmers farming Chinese catfish is basically maintained between 15,000 and 20,000 yuan. Moreover, the growth cycle of catfish is short, basically 80 to 90 days, and two seasons can be produced a year.

(2) According to this calculation method, assuming a catfish farming area of 10 mu, the minimum annual net profit is 15,000 yuan/mu * 10 mu * 2 seasons = 300,000 yuan.

3. What is the farming outlook?

(1) At present, Wels catfish and catfish hybrids have gradually been recognized by the market. Market consumption and market share are also increasing year by year, and their prices are at the highest end of the catfish market.

(2) Wels catfish has the highest price in the catfish market. In addition, it grows quickly. Stocked 10 cm fry can generally grow to more than 2 jin in 3 months. In Central China, 2 seasons of fish can be produced a year. Feed costs are low, and ponds with good conditions can be used for high-density farming. The market price is 1 to 2 yuan per jin higher than that of large-mouth catfish, and farming benefits are good.

(3) The catfish hybrid is a cross between local catfish and Wels catfish. Its body color is relatively yellow, it grows quickly, its feed conversion ratio is slightly higher than that of Wels catfish, its body shape is good, and it is highly recognized by the market. Its price is slightly lower than that of Wels catfish.

2. What are the differences between native catfish, catfish, and large-mouth catfish?

1. What are the differences from catfish?

(1) Differences in morphology:

Native catfish, that is, local catfish, is in the family Siluridae and genus Silurus. Its body is elongated and laterally compressed toward the rear. The head is flat. The mouth is large, and the end of the mouth cleft stops below the front edge of the eye. The lower jaw protrudes, and both the upper and lower jaws have fine teeth. Adult fish have 2 pairs of barbels, and 1 pair of maxillary barbels reaches the end of the pectoral fin. The front edge of the pectoral fin spine has obvious serrations. The base of the anal fin is very long, with many fin rays. The caudal fin is small and slightly concave, with the upper and lower lobes equal in length. Long barbels grow on both gill areas. The meat is delicious and nutritious, making it a delicacy among fish.

Catfish: Animalia - Chordata - Vertebrata - Actinopterygii - Siluriformes - Siluridae - Silurus - catfish species. It has a total of 4 barbels on its mouth, the upper ones long and the lower ones short. It is carnivorous, mostly wild, has low requirements for water quality, and can be artificially farmed. It grows relatively quickly, and some varieties can grow very large.

(2) Differences in distribution range:

Catfish are distributed throughout the world and are ferocious bottom-dwelling fish. Native catfish mainly live in the middle and lower layers of rivers, lakes, reservoirs and ponds, and are mostly active in coastal areas. During the day, they mostly hide in grass, under stones or at the bottom of deep water. They generally forage frequently at night. After autumn, they live in deep water and active mud to overwinter, and their feeding intensity also weakens.

2. What are the differences from large-mouth catfish?

(1) Differences in body form

Large-mouth catfish are larger than native catfish. Native catfish have spots on their bodies and are relatively small. Large-mouth catfish are relatively large, with the largest capable of growing to 60 jin, while most are just over 2 jin. Their body surface is dark gray, and a small number have spots.

(2) Differences in distribution range

Large-mouth catfish are basically distributed south of the Yangtze River. They are an economic fish species. Because they grow quickly, most are used as farmed fish to supply the market. Therefore, the catfish bought on the market are basically this variety.

(3) Differences in weight

Native catfish are distributed throughout the country. The vast majority of catfish caught by anglers in the north are native catfish. Native catfish are generally not large in size, commonly around 6 liang to 1.5 jin, with the largest only 5 to 6 jin.
