Freshwater shrimp farming how much profit per mu pollution-free freshwater shrimp farming technology

Because there are many varieties of freshwater shrimp in our country, and the nutritional value of freshwater shrimp is very rich. The taste and nutritional value of different species of freshwater shrimp are also different, so freshwater shrimp can meet the needs of different people, and now many people have begun to cultivate freshwater shrimp, so what are the culture techniques of freshwater shrimp? And what do you need to pay attention to in breeding freshwater shrimp?

What is the profit of freshwater shrimp farming per mu?

The main results are as follows: 1. The number of female shrimp per mu is: 120jin / mu × 20 / jin = 2400 / mu. 1140 / mu × 200 / time × 2 times / year = 456000 / mu one year.

2. The survival rate from spawning to young shrimp is 8% to 30%. According to the lowest 8%, the total number of annual adult shrimp is 456000 / year × 8% / mu.

3. It can be put on the market after spawning for 2-3 months, the weight of each adult shrimp grows to 50 grams (about 10 / jin), and the total annual output per mu is: 36480 / mu? Annual / 12 / jin = 3040 jin / mu? Year. The annual gross profit per mu is: 3040 jin × 8 yuan / jin = 24320 yuan / mu net profit = 24320 yuan-seed purchase cost (120jin × 48 yuan) 5760 yuan = 18560 yuan / mu.

Culture technology of pollution-free freshwater shrimp

1. Soil pollution-free freshwater shrimp does not have high requirements for soil quality. Clay, loam and sandy loam all require good water retention, moderate air permeability, strong dikes and flood resistance.

2. Water supply includes edible water and aquaculture water. Potable water must meet the standard of drinking water at home. Aquaculture water requires sufficient water quantity, fresh and pollution-free water source, and no peculiar smell, odor and color.

3. Atmospheric environmental quality is also one of the important factors affecting pollution-free freshwater shrimp culture. pollutants such as total suspended particles, sulfur dioxide, nitrogen oxides and fluoride in the atmosphere around freshwater shrimp farms should be within the atmospheric environmental quality limits for pollution-free aquatic products production.

4. Feeding and management shrimp fry entered the stage of commercial shrimp breeding and management after stocking. In the daily feeding of commercial shrimp, the feed feeding should follow the "four fixed" feeding principle, and achieve the quality, quantity, positioning and timing.

What should be paid attention to in raising freshwater shrimp?

1. Freshwater shrimp culture should first pay attention to the choice of ponds. Generally, freshwater ponds with an area of three to five mu, a water depth of 1.5 to two and a half meters, sufficient freshwater resources, no pollution and sandy bottom are the best, or ponds that have raised freshwater shrimp are the best.

2. Freshwater shrimp seedlings in the week before the animals were released, the medicinal sieve silk net filtered the impurities in the pond and fattened the pond water, that is, to cultivate the basic bait. Freshwater shrimp seedlings are best released in late May. Shrimp seedlings need to live in fresh water for more than a week, and there is no need to feed them one month before they are released, because the plankton in the pond is enough to eat. A month later, put an appropriate amount of feed into the pond every day.

3. After ten days of release of freshwater shrimp, gradually inject new water into the pond, add 10 to 15 centimeters of water every week, change water every day in high temperature weather, and regularly sprinkle quicklime into the pond for disinfection, which can not only play the role of sterilization and disinfection, but also improve water quality and sediment quality, and promote shelling growth.

Do you make money by raising freshwater shrimp?

The main results are as follows: 1. Due to the large market demand of freshwater shrimp, the limited amount of wild resources, and the decreasing catch due to the pollution of river waters, the prospect of artificial culture is promising. Some experts believe that as long as raised properly, the benefit of raising freshwater shrimp per mu is 6-8 times that of fish farming, or even more.

2. Freshwater shrimp culture is not complicated. Generally, ponds with sand mud at the bottom of the pond with a water depth of 1-1.5 meters can be used as freshwater shrimp culture ponds. The ponds should be close to the water source in order to drain water in time and increase oxygen. River shrimp is omnivorous, it has strong fecundity and fast growth, and it can also be mixed with silver carp, dace and other non-carnivorous fish.

In the above introduction, I have taught you some scientific and technical points for attention in cultivating freshwater shrimp. Has everyone learned it? In fact, the commercial prospect of freshwater shrimp is relatively good. After all, freshwater shrimp is very popular and loved by people in China.
