1 put 500 pounds of specifications acre 5-8cm Loach seedlings, about 150 per catty, the total dropping the number of seedlings per acre 7.5-8.5 ten thousand, Hong the mahi growth cycle for about 100 days, from seedlings devoted to farming commodity Loach, catty Hong mahi need to feed 1.5-1.8 Jin 1.5-2 yuan per catty (ie feed conversion ratio) containing eggs, the amount of 28/32%, feed prices equal to the cost of feed to raise a pound of incense mahi 1.5-2 million. 3,1 Jin Hong Loach, the growing season of about 100 days, can be increased by 7-10 times, then put in the per acre yield of 500 Jin Hong mahi 3500-5000 Jin Hong Loach, the output value of 45 000 -5 million. The output value of 4, the sales value of 3500 × average market price = 45,500 yuan / jin / mu "of saplings + feed costs + land rental fees + Tangkou construction fee / mu the + drugs utilities" 45500 - 14000 +7000 +500 +500 +100] = 23,400 yuan
