Green shrimp breeding techniques

Green prawns are one of the main species in pond aquaculture. Cultivating good seedlings plays an important role in increasing yield, reducing disease, and increasing profits, and it is also one of the key measures for aquaculture. The beginning of May is a good season for the growth of shrimp. Technically, the following work should be done.
The nursery pond selection area is preferably 3 to 7 mu, the pool depth is 1.2 to 1.5 meters, the pool slope ratio is 1:2.5, and the bottom of the pool is flat. In the pond, shrimp ditches are excavated, and the drainage area should be inclined to facilitate catching shrimp. The inlet is filtered with a 40-mesh or 60-mesh sieve to prevent small fish and their eggs from entering the pool. The broodstock is bathed for 7 to 10 days before stocking, and 50 to 75 kilograms of clear lime is used for disinfection per acre.
The breeding time for broodstock broodstock is from mid-May to late June. Wild shrimp in lakes is preferred; ponds reserved for individual shrimps are large, disease-free, non-injury, neat and well-fertilized. Kind of shrimp. Restocking 4-6 kg per acre.
Water quality management Stocking broodstock pool water in the early stage, water depth of 50 to 60 cm, 3 to 5 days after the broodstock into the pool, add appropriate amount of micro-water per day to promote broodstock ovulation, 7 to 10 days after hatchling hatchlings, each Mushi Fermented Organic Fertilizer 200-300 kg, cultivating plankton as a natural opening feed for shrimps.
The feed was fed to the broodstock and fed on the pellet feed of highland barley, wheat bran, or green shrimp No. 2. The daily feeding amount was 5% to 8% of the pond shrimp weight, and they were fed once in the morning and in the afternoon. After the hatchlings of the hatchlings were hatched, Feed soybean milk, fish meal, and EM bacteria bio-agent (in a ratio of 10:3:3); shrimps can be fed with barley and bran when swimming in pools.
After shrimps are caught in early July, shrimps will be caught when they grow to 1.2 to 1.5 cm. If there is a wild fish in the pool, it is cleared with 150 grams of Qingtang Ling in 1 meter deep water per acre on sunny days, and nets are pulled from 5 to 7 days later. Generally, about 500,000 shrimp seedlings can be produced per acre, which can meet the needs of 6-7 mu shrimp farming.

Rice is a finished product made after the process of rice cleaning, glutinous rice, rice milling, and finished product finishing. The embryo and aleurone layer of rice contain nearly 64% of rice nutrients and more than 90% of the nutrients required by the human body. It is the main food of the people of the South.
The carbohydrate in rice is mainly starch, and the edible rice has higher nutritional value.
Storage taboo
Rice should not be stored at the same time as foods with high moisture such as fish, meat, vegetables, etc., otherwise it will easily cause water to cause mildew; rice should not be stored directly on the ground, and should be placed on a dry, ventilated and clean pad; indoors should be stored with high moisture content. Otherwise, it is easy to absorb water and cause mildew; the family avoids rice stored in the kitchen because the kitchen has high temperature and high humidity, which has a great influence on the quality of rice.
