1. Feed: After the shrimp is put into the shrimp Tangqian for one week, it is filtered with a 60-80 mesh sieve. First, 30 cm is put, and 50 kg of base fertilizer or 5 kg of urea are applied to one mu to cultivate the basic feed. It can also save some costs and try to keep the transparency of the pool water at about 30 cm.
2. Stocking preparation: When establishing a shrimp pond, the stocking density should be well controlled, and the density should be determined according to the size of the shrimp pond. Under normal circumstances, if the yield per mu is 80 kg, then more than 80,000 seedlings should be invested. Conditions are good or bad. If possible, an aerator can be set in the shrimp pond, which can achieve a good aerobic effect with excessive density.
3. Feed: The feeding habits of river shrimps are quite diverse, and relatively speaking, more attention should be paid to the diversity of feed. 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 of water quality. At other times, water should be changed frequently in hot season. Disinfect with lime every half month to ensure the sterility of water source and improve water quality. From August to 10 every year, the stock of prawns will increase greatly. At this time, the climate changes greatly, which is easy to cause hypoxia. It is best to prepare a shrimp pond aerator.
Living habits
Shrimp is an omnivorous aquatic animal, which eats animal feed, and its artificial reproduction is mainly based on commercial feed. The optimum growth water temperature is 18-30℃, and when the water temperature drops to 4℃, it enters the wintering period. When the water temperature rises above 10℃, the vitality and food intake gradually increase.
I like to live in areas with slow water grass flow, and the habitat depth ranges from 1-2 meters to 6-7 meters. In summer and autumn, river shrimps look for breeding in the shallow waters along the shore. In winter, you will enter deeper waters and rarely eat and move.
When the water temperature is about 18℃, the sexually mature shrimp begin to mate and lay eggs, and mating often occurs near the time of laying eggs. Shrimp is backlit, hiding in the dark during the day and coming out at night. The breeding season is atypical. It will mate during the day, and when it comes to feeding, it will come out to eat during the day.
