The cost of cultivating oysters is about 2000 yuan per mu, and the profit per mu is about 5000- 12000 yuan. So take 3000 times 5000= 15000000 yuan, and 3000 times 12000 yuan = 360000000 yuan. The specific profit mainly depends on the market price and breeding cost.

The investment cost of breeding oysters also depends on the situation. The average input cost per mu is above 1 10,000 yuan. According to our own decision, the breeding cycle of oysters is 8 months to one year.
