Shrimp generally refers to small river shrimp, which belongs to omnivorous animals. Young shrimp mainly feed on plankton, while adult shrimp mainly feed on aquatic animal carcasses, organic debris, plant debris and various benthic small invertebrates. Choose a freshwater pond with an area of 3-5 mu, a water depth of 1.5-2.5 m, sufficient fresh water sources, no pollution and sandy bottom when cultivating. In late May, when the water temperature is stable at 1 8-20 C, shrimp seedlings can be released, and they need to be desalinated for more than1week.

First, what do shrimps eat and how do they feed?

1, small shrimp mainly refers to small river shrimp, which belongs to omnivorous animals. Young shrimp generally feed on plankton, while adult shrimp feed on aquatic animal carcasses, organic debris, plant debris and various benthic small invertebrates. Shrimp can also be fed with various commercial feeds during artificial culture, such as distiller's grains, bean curd residue, bean cake, wheat flour, rice flour, etc., and the culture water temperature must be controlled at 18-30? C。

2. When cultivating shrimp, it is necessary to choose a freshwater pond or shrimp pond with an area of 3-5 mu, a water depth of 1.5-2.5 m, sufficient fresh water sources, no pollution and sandy bottom. Before the shrimp fry are stocked 1 week, they can be filtered with a 60-80 mesh sieve, then 30 cm of water is injected, and 50 kg of base fertilizer or 5 kg of urea are applied per mu to cultivate the basic bait.

3. Generally, the water temperature is stable at 18-20 in late May. C, shrimp seedlings can be released. Shrimp seedlings must be desalinated for more than 1 week, and can only be released when the specific gravity is below 1.003. Generally, 0.7- 1.0 cm can be used for 30,000-40,000 shrimps per mu, and the shrimps below 0.7 cm need to be temporarily raised, and 80- 150 silverfish can be mixed in the shrimp pond. Generally, after 80- 100 days of cultivation, shrimps can be caught and sold according to market conditions when they are as long as 7- 10 cm.

Second, can freshwater shrimps be farmed artificially?

1, water quality

The water quality of freshwater shrimp must be good, and it is generally better to raise fresh water such as rivers and streams. If there is no such water source, it can be raised with tap water, but it needs to be exposed to the sun for 3-5 days in advance before use. Secondly, it should be noted that water must be changed every 1-2 days. The pond where freshwater shrimps live should be built in a place with sunny ventilation, sufficient water, no pollution source and convenient water injection and drainage, and then dredged, trimmed and exposed.

2. Water temperature

Freshwater shrimps are sensitive in constitution, so long as the water temperature rises from the standard requirement 1? C will die, so when raising freshwater shrimps, we should always pay attention to adjusting the temperature in the pond, especially when the shrimps are just stocked, the water temperature must be controlled.

3. Feeding

Freshwater shrimps are mainly fed with aquatic organisms, aquatic insects, plant debris, organic debris and fish feed, and some meat foam can also be fed appropriately.
