The renovation cost of one mu of paddy field is around 500 yuan, and 600 Jin (30,000 loaches) can be planted in one mu of paddy field. The market price of loach is around 10~ 15, which is about 6000 yuan according to 10 yuan/kg. After feeding for 6-8 months, the body weight can be increased by 3-5 times, and the yield per mu can reach about 2400 kg according to 4 times. The feeding cost is 7000 yuan (including medicine).

Total investment cost per mu: 500+6000+7000= 13500 yuan. The annual output value is 3 1.200 yuan, and the annual net profit of planting one mu of paddy field is above 1.5 million. Ten acres of land, you calculate it yourself! Wish you success!
