Profit and cost of shrimp farming

Shrimp raising cost 120kg/ mu, shrimp quantity 120kg/ mu * 22/kg = 2640/ mu, and the ratio of male to female shrimp 1: 1, each 1320. If the loss in transportation is calculated as 5%, the number of female shrimps per mu is 1254.

56 yuan per catty of each kind of shrimp, shrimp raising cost 120*56 yuan =6720 yuan. The total number of young shrimps produced after one year of lobster culture per mu is: per mu 1254 * twice per mu. Year *200/ mu = 50. 1.6 million/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 mu per year is 50 16000*8%=40 128. 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. So the gross profit per mu is 40 12.8* 10 yuan/kg =40 128 yuan/mu. Net profit of shrimp culture = gross profit 40 128 yuan-shrimp culture 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 service and pond lease year, and the salary of labor service is 13000 yuan/year. 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? When selecting special feed for prawns, priority should be given to selecting high-quality feed from regular manufacturers in order to improve feed utilization and ensure the healthy and rapid growth of prawns. In the later stage, we can cultivate enough biological feed, put in fresh feed and special feed for young shrimp, and then gradually transfer the special feed for shrimp.
