One acre is 666 square meters, and under high-density farming, one square meter will raise about 50 eels, each weighing 1 two. The yield of one acre is: 0.1 catty * 50 articles * 666 square meters = 3330 pounds. The purchase price of eels is 30 dollars a catty. Then you can sell 3330 pounds * $30 = $99,900 ≈ 100,000 yuan per acre. But if you can retail them all yourself ($60 a pound), the price will double.
Some of the eel farming areas require only 50,000 yuan (or even less) for seedling and feed combined, even if the income from net-pen farming is only 60,000 yuan, minus 16,580 yuan for equipment in the first year.
The first year is only a loss of 6580 yuan, the second year is nearly 10,000 yuan of income, their own labor costs can be shared by expanding the breeding area, a person to raise 10 acres is no problem.
