The price of each kind of shrimp is 56 yuan per catty, and the cost of raising shrimp 120*56 yuan =6720 yuan. The total number of young shrimps produced after one acre of lobster culture for one year is: 1254 per acre *2 times per acre. Year *200/ mu = 50.160,000/mu. Year. The survival rate of shrimp species from spawning to young shrimp is 8%-30%.
According to the lowest calculation, the total number of adult shrimps per year is 50 16000*8%=40 128 per mu. Year. After laying eggs and feeding for 2-3 months, it can be put on the market for sale. Each adult shrimp weighs about 50g, and the annual output per mu is 4012810/kg = 4012.8kg/mu. Year. The gross profit per mu is 40 12.8* 10 yuan/kg =40 128 yuan/mu. Net profit of shrimp farming = gross profit 40 128 yuan-shrimp farming cost 6720 yuan-feed and other expenses 2880 yuan =30528 yuan.
Therefore, the theoretical profit value of one mu of shrimp culture is 30528 yuan. If 10 mu shrimp needs 1000 yuan/mu. Labor and pond lease year, labor wage 13000 yuan/year. Mu, 10 mu shrimp farming income is 30528-13000-1000 =16528 *10 =165280 yuan. Matters needing attention in shrimp culture 4. 1 Choose a good feed? In the selection of special feed for shrimp, priority should be given to the selection of high-quality feed from regular manufacturers in order to improve the utilization rate of feed and ensure the healthy and rapid growth of shrimp. In the later stage, sufficient biological feed can be cultivated, fresh feed and special feed for young shrimp can be put in, and then special feed for shrimp can be gradually transferred.
