CATDOLL : CATDOLL: How much does it cost to raise white carp per pound?

One acre of fish pond can raise 800-3,000 native grass carp. The cost per acre includes the cost of fish fry, pond rent, feed, etc. If the yield of native grass carp per acre is 2,000 kilograms, the income can be 20,000 yuan. After deducting the cost, the net profit is 5,000 yuan. This has a lot to do with the breeding model. Through the rational use of feed by farmers and the adjustment of the timing of fish release, the profit can be considerable.

Mud carp is one of the important economic fish species and pond aquaculture species in the south. This species has the characteristics of omnivorous diet, high yield, wide feed source, tender meat and delicious taste, and is deeply loved by consumers and anglers.

At present, the price of grass carp is 10-15 yuan/catty, and the prices in different regions will vary. For example, the price in Doumen District, Zhuhai, Guangdong today is 10 yuan/catty, and the price in Jiangnan District, Nanning City, Guangxi today is 16.33 yuan/catty.

Mud carp culture technology

1. Pond conditions

The pond area should be 5-8 mu, the water depth should be 1.2-1.5 meters, the pond silt should be about 20 centimeters, the water quality should be fresh, pollution-free, and easy to fill and drain.

2. Pond cleaning and disinfection

The pond needs to be dried and exposed to the sun 3 days before stocking the fry, and then disinfected with 2.5 kg/mu of bleach.

3. Water quality management

The pond should be fed with clean water for 5-7 days after the fry are put into use. Fertilizer water should not be used and the water level should be controlled at 0.6-0.8 meters. Appropriate fertilizer can be applied after 5-7 days. Generally, 5-7.5 kg of chicken manure pellets are needed per mu and they are evenly distributed throughout the pond. The transparency of the pond water should be controlled at about 30 centimeters. Water should be added once every 7-10 days in a normal pond and the water level should be controlled at 1.2-1.5 meters.

4. Summer flower pond

The dace fry are first raised in the ponds from early June to late July. The size is 0.3 cm and the stocking rate is 300,000 to 600,000 per mu. They need to be cultivated for 15 to 20 days and then separated out of the ponds. They are 2 to 3 cm in size and have a survival rate of 60-65%. Then they are planned to be separated according to the breeding conditions and the food intake of mandarin fish.

5. Stocking of fish fry into ponds

The breeding period is from late June to early October, which can be divided into three stages. According to the breeding production in our city, the first stage is from late June to early August (generally, the first breeding is the main method according to the market supply and demand in our city), the stocking specification is 5000-7000 per kilogram, 40,000-50,000 dace fry/mu, the pond-out specification is 120-150 per kilogram, and the yield per mu is 300-320 kilograms. The second stage is from early August to early September, the stocking specification is from early September to early October, the stocking specification is 1000-1200 per kilogram, 10,000 dace fry/mu, the pond-out specification is 50-60, and the yield per mu is 160-180 kilograms. Reasonable arrangement of each crop match can reach 500-600 kilograms per mu.
