Shrimp farming methods
prawn culture method
Shrimp, as a high-protein, low-fat aquatic product, is deeply loved by consumers. In recent years, China's shrimp aquaculture industry has achieved remarkable results, not only to meet the domestic market demand, but also exported to various countries worldwide. In order to improve the efficiency of shrimp farming, it is important to master the correct farming methods.
First, the selection of varieties
1.Local species: such as Chinese prawn, giant river prawn, etc., have strong adaptability and reproductive ability, and are suitable for breeding in various parts of China.
2.Alien species: such as Penaeus vannamei shrimp, Penaeus monodon, etc., have the characteristics of fast growth rate and delicious meat quality, but the adaptability is weak, and attention should be paid to the introduction and domestication.
Creation of breeding environment
Pond construction
Choose a plot with sufficient water source, good water quality and convenient transportation to build a breeding pond. The pond area is generally 5-10 acres, and the water depth is 15-2 meters, the bottom of the pond is preferably loam or sandy loam.
Water quality management
Ensure that the water quality is fresh and the dissolved oxygen is sufficient. Measures such as regular water changes and aeration pumps can be used.
Habitat settings
Provide sufficient habitat and shelter for shrimp, such as setting up artificial reefs, aquatic weeds, etc.
Key points of breeding technology
OneShrimp seedlings to buy shrimp seedlings to buy: choose regular manufacturers, healthy, pest-free shrimp seedlings. Before stocking, shrimp seedlings need to be desalined and domesticated to improve the survival rate.
IIStocking density: According to the breeding species, pond conditions and other factors, the stocking density is reasonably controlled, generally 2000-3000 per mu.
ThreeFeed managementFeed management: select high-quality shrimp feed, follow the principle of "small quantities and multiple meals", and feed them 2-3 times a day.
IVDisease prevention and controlDisease control: Strengthen disease monitoring, take timely measures to prevent and control diseases, prevention first, supplemented by **.
WooBreeding cycleBreeding cycle: According to different varieties, the breeding cycle is generally about 60-90 days.
BenefitsAnalysis of breeding benefits
YieldAccording to the breeding species, breeding conditions and other factors, the shrimp aquaculture output can reach 300-500 kg per mu.
IncomeThe income of farmed shrimp mainly includes the sale of shrimp seedlings and adult shrimp, etc., and the market prospect is broad.
CostIt mainly includes shrimp seedlings, feed, drugs, equipment, etc., and controlling costs is conducive to improving the efficiency of aquaculture.
In short, mastering the correct shrimp farming methods and paying attention to the management of the breeding environment and technology are expected to achieve high-yield and efficient shrimp farming. In the process of developing the shrimp aquaculture industry, it is necessary to continue to learn and explore to meet the market demand and improve the level of aquaculture technology.
