First, what conditions are needed for shrimp farming in rural areas?
1, attention should be paid to when artificially raising shrimp, whether it is a dug pond or a cement pond, the water quality standard in the pond must conform to the growth of river shrimp, and the oxygen content in the water must be sufficient; The depth of the water should be about one meter and a half, and the silt should be less. At the same time, there should be no large predatory fish in the water, and aquatic plants must be rich.
2. When shrimp are farmed artificially, some of them can be fed shrimp feed. However, it is worth noting that river shrimps prefer to eat animal feed, so the feed is fed with certain activities, such as river snails, small fish, cicada pupae and so on.
3. When fishing shrimp, in order not to affect the appearance of shrimp, cage fishing can be adopted to avoid hurting shrimp. There should be a plan on the time of catching shrimp, because there will be a certain amount of death after shrimp breeding, so after shrimp breeding in May-June, shrimp can be caught in 7-8 months.
Second, how to raise shrimp
1, aquaculture facilities
The pond area of freshwater shrimp is preferably 4- 10 mu, and the bottom should be flat and loam is better. Moreover, the water retention is good, the water level and water source can be controlled, the water should be pollution-free, and at the same time, facilities to prevent escape must be built.
2, pool cleaning and disinfection
Freshwater shrimp seedlings must be drained within 20-30 days before stocking, remove excess sludge and repair pond stalks. Using 75 kilograms of quicklime bleaching powder or medicine per mu can thoroughly clean and disinfect the pond.
3. Apply sufficient fertilizer to the bottom layer
Freshwater shrimp ponds can release 500-600 kilograms of rotten livestock manure per mu, and cultivate rotifers, cladocera and plankton for larvae to eat.
4, planting good aquatic plants
Freshwater shrimp ponds can be planted with aquatic plants such as black algae, POTAMOGETON malayi and Elodea, accounting for two-thirds of the total area of shrimp ponds. At the same time, it is also necessary to erect nets or set up bamboo tubes, plastic buckets and other places for shrimp to inhabit and hide their molting every time.
5. Feed selection
Freshwater shrimp are usually omnivores. You can feed it some small fish pieces, dried fish meal, clam meat and various animal scraps, and you can also feed it various vegetables and forage such as rapeseed cake, soybean meal, bran, wheat, corn and pumpkin.
6. Feeding and feeding
Freshwater lobsters mostly feed at night, with feeding time at 10 every morning and 4 pm. The food intake in the afternoon accounts for about 70% of the total food intake, and the daily food intake is appropriately increased or decreased according to the weather, water quality and shrimp foraging conditions.
