How to raise river shrimp: feed, stocking preparation, feed, management.

1, feed

One week before the shrimp will be put into the shrimp pond, we will use 60-80 mesh sieve filtration, the first 30 centimeters, an acre of basal fertilizer 50 kilograms or apply 5 kilograms of urea in order to cultivate the basic feed. You can also save part of the cost, try to keep the transparency of the pond water about 30 centimeters up and down.

2, stocking preparation

Establishment of shrimp ponds should be controlled stocking density, density should be determined according to the size of the shrimp pond. In general, if the yield of one acre is 80 kilograms, then the corresponding seedlings should be invested more than 80, 000 tails. If the conditions are good or bad, if there are conditions, shrimp ponds to get an oxygenator, it can achieve excessive density of good oxygenation.

3, feed

River shrimp have a mixed diet, relatively speaking, the diversity of feed should be more attention. Feed should not be fed too much. Feed should be changed regularly to ensure a balanced intake of nutrients.

4, management

Under normal circumstances, it is only necessary to observe the cleanliness and hygiene of the water. At other times, it is necessary to change the water frequently during the hot season. Lime should be used for sterilization every half a month to ensure sterility of the water. During the period from August to October each year, the stock of shrimp increases considerably, because at this time the climate change is very strong, so it is easy to cause oxygen deficiency, so it is best to prepare a shrimp pond oxygenator.

Habitat

River shrimp is an omnivorous aquatic animals, eating animal feed, artificial reproduction is mainly based on commercial feed. The optimal growth water temperature is 18-30 ° C. When the water temperature drops to 4 ° C, into the overwintering period. When the water temperature rises above 10°C, the vigor increases and food intake is gradually enhanced.

Prefer to live in areas where aquatic vegetation moves slowly, with habitat depths ranging from 1-2 meters to 6-7 meters. During the summer and fall, the river shrimp seeks out and breeds in shallow water along the banks. In the winter it will move into deeper waters during the winter months with little feeding or activity.

Sexually mature river prawns begin to mate and lay eggs around 18°C. Mating often takes place near the spawn. The river shrimp is backlit, hiding in the dark during the day and coming out at night. The breeding season is atypical in that it will show mating activity during the day and when it comes to feeding it will come out during the day to eat.
