CATDOLL : CATDOLL: How much does it cost to raise crayfish per acre (what is the cost of raising crayfish? Are the main expenses the cost of shrimp seedlings and pond construction?)

1. How much investment is needed to raise crayfish per acre?

At present, the annual profit of one acre of lobster farming is as follows: one acre is about 20,000 yuan, which is the best profit margin. Site rental: There are many idle land resources in rural areas, and the annual rental of one acre of land is about 700 yuan.

The cost of breeding shrimp: The market price of one kilogram of breeding shrimp is 58 yuan. One acre of shrimp pond can release about 120 kilograms of shrimp fry, and the cost of breeding shrimp is 6,960 yuan.

Feed cost: Crayfish are omnivorous animals that feed on mud, algae, shrimp, small fish, etc. Generally, the feed cost for one acre of crayfish is 2,000 yuan.

Water and electricity costs: 1,000 yuan Staff wages: One person is enough to manage one acre of crayfish. Therefore, if the farmers can manage it themselves, they can save this expense.

Calculation of the cost of raising crayfish: raising cost = site rental + cost of breeding shrimp + feed cost + water and electricity cost + staff salary (negligible) = 700 + 6960 + 2000 + 1000 = 10660 yuan. Lobster raising profit = raising income - raising cost = 30000-10660 = 19340 yuan.

2. What is the cost of raising crayfish? Are the main expenses the cost of shrimp fry and pond construction?

The breeding cost of one acre of crayfish is about 4,600 yuan. Assuming 100 kilograms of crayfish seedlings are released per acre, the seedling introduction fee is about 12 yuan per kilogram. The total cost of one acre is: shrimp seedling introduction fee of about 1,200 yuan, pond construction of about 1,500 yuan, land rent of about 600 yuan, infrastructure of about 500 yuan, feed of about 500 yuan, water, electricity and medical care of about 300 yuan, totaling about 4,600 yuan.

Crayfish farming costs:

1. Introduction of shrimp fry: The current market price of shrimp fry is about 6-16 yuan/jin. Generally, about 90-110 jin are released per mu. Calculated as 12 yuan for 100 jin and shrimp fry price, introducing 90 jin of fry will cost about 12 yuan/jin x 100 jin = 1,200 yuan.

2. Pond construction: The construction of a pond for lobster farming costs about 1,500 yuan.

3. Land rent: The rent varies from place to place, and is approximately RMB 600.

4. Infrastructure: Fishing tools, aquatic plants and other infrastructure cost about 500 yuan per mu.

5. Feed cost: about 500 yuan.

6. Water, electricity and medical expenses: approximately RMB 300.

To summarize, the cost of raising crayfish is calculated at 100 jin/mu and 12 yuan per jin of shrimp fry. It includes 1,200 yuan for introducing shrimp fry + 1,500 yuan for pond construction + 600 yuan for land rent + 500 yuan for infrastructure + 500 yuan for feed + 300 yuan for water, electricity and medical care = 4,600 yuan.

Crayfish breeding method:

1. Crayfish have strong adaptability and a wide range of temperature adaptability. They can grow normally in temperatures of 10-30℃, are drought-resistant and cold-resistant, and like to dig holes during the breeding season. Their holes are generally about 20cm above the surface of the pond water and about 60-120cm deep. There is a small amount of accumulated water inside, and the hole entrances are mostly sealed with mud caps to reduce water loss. On summer nights or after heavy rains, they will climb ashore, cross the dam and enter other water bodies.

2. Select fields with good water quality, no pollution, strong water retention capacity, convenient irrigation and drainage, and will not be flooded for breeding. Dig shrimp ditches around the inner ridges of the rice fields. The ditch width is controlled at 1.5m and the depth is controlled at about 1m. If the field is large, dig field ditches in the middle of the rice field. The width of the field ditch is controlled at 1m and the depth is controlled at 0.5m. The area of ​​shrimp breeding ditches and field ditches accounts for about 20% of the total area of ​​rice fields.

3. At a distance of 1m from the ridge, drive a 1.5m high stake every 3m and use bamboo to set it up. Plant melons, beans, gourds, etc. on the edge of the ridge. After the vines are on the racks, they will provide shade and summer heat for the lobsters.

4. Before releasing crayfish, you must first test the water, and then release the shrimp after it is safe. After the rice is harvested, release the breeding shrimp into the rice fields in early September and allow them to reproduce on their own. They can be raised in ponds, low-lying areas, rivers and rice fields.

5. Before releasing crayfish, soak them in 3-4% salt water for 10 minutes for disinfection. The release specifications in the same field should be uniform and sufficient crayfish should be released on sunny mornings or rainy days.

3. How much does it cost to raise 2 acres of crayfish?

It costs about 10,000 yuan to raise two acres of crayfish.

The investment cost of raising crayfish per mu is about 6,000-9,000 yuan. The conventional breeding method is to put about 60 kilograms of seedlings per mu. The price of seedlings is about 15-30 yuan per kilogram, so the cost of seedlings is about 900-1,800 yuan. Other costs include feed, escape-proof nets, disinfectants, oxygenators, labor costs, etc. The comprehensive cost is about 7,000 yuan on average. Due to different regions, the breeding cost calculation will also vary.
