How much do you usually earn per acre of shrimp a year?
1. Cost of raising shrimp

Each acre is released according to120kg shrimp, and the release amount is120kg/mu *22 shrimps/kg =2640 shrimps/mu, and the ratio of male and female shrimps is 1: 1, and each shrimp is released 1320. If the loss in transportation is calculated as 5%, the number of female shrimps per mu is 1254. The price of shrimp per catty is 56 yuan, and the cost of shrimp breeding is 120*56 yuan =6720 yuan.

2. Income from shrimp farming

The total number of young shrimps produced after one acre of lobster culture for one year is: 1254/acre *2 times/year *200/time =50 1600/acre. The survival rate of spawning shrimp is 8%-30% in the process of growing into young shrimp. According to the lowest calculation, the annual total number of adult shrimp is 50 16000*8%=40 128/mu. year. After spawning, it can be put on the market for 2-3 months. Each adult shrimp weighs about 50 grams, and the total annual output per mu is 40 128÷ 10/kg =40 12.8 kg/mu. In this way, the gross profit per mu is 40 12.8* 10 yuan/kg =40 128 yuan/mu.

3. Profit from shrimp farming

Net profit = gross profit 40 128 yuan-shrimp breeding cost 6720 yuan-feed and other expenses 2880 yuan =30528 yuan. Therefore, the theoretical profit of shrimp farming is 30,528 yuan per mu. If shrimp farming 10 mu requires labor, pond rent 1000 yuan/mu. year and labor wage13,000 yuan/year. mu, then shrimp farming 10 mu.

4. Matters needing attention in shrimp culture

(1) Choosing a good feed In the selection of special feed for shrimp, priority should be given to the high-quality feed from regular manufacturers, so as to improve the utilization rate of feed and ensure the healthy and rapid growth of shrimp. In the later stage, sufficient biological bait can be cultivated, and fresh bait and special feed for young shrimp can be put in, and then gradually transition to special feed for shrimp.

(2) The general principle of reasonable feeding shrimp is a small number of times, and it is not allowed to waste feed because of too much feeding or affect the normal growth of shrimp because of too little feeding. At the same time, it is necessary to determine the feeding amount according to the weather conditions. If the water temperature is lower than 18 degrees or higher than 32 degrees, feed less. When the water temperature is between 25 and 30 degrees, shrimp will grow vigorously and demand is large, so feed more.

(3) maintain good water quality shrimp culture needs good water quality conditions, good water quality, shrimp can grow well, less sick. Therefore, it is necessary to change the water once every 10 day, and change the water by about 30% each time.

The above analysis on the profit and cost of shrimp culture is for your reference only, and there will be differences in reality due to the fluctuation of culture technology and market conditions.
