Construction of breeding ponds.
The shrimp breeding pond should be selected in a place with flat terrain, sufficient water source, fresh water quality and no pollution. The area of the breeding pond should not be too large or too small, generally 5-10 acres, and the water depth is 15-2 meters. The bottom of the pond should be silty, the bottom of the pond should be flat, slightly inclined towards the drain. Anti-escape facilities should be set up around the breeding pond to prevent the escape of green shrimp.
Seedling selection and stocking.
The stocking density should be comprehensively considered according to factors such as breeding conditions, technical level, water quality and bait conditions. Generally, 3-50,000 shrimp seedlings are stocked per mu, and the size is 3-5 cm. Shrimp fry should be disinfected before stocking to improve the survival rate.
Bait and feeding.
Green shrimp is an omnivorous animal, and the requirements for bait are not high, but in order to improve the efficiency of breeding, high-quality and nutritious bait should be selected for feeding. Common baits are rice bran, bran, soybean meal, fishmeal, etc. The amount of feeding should be determined according to the feeding habits, growth status, water quality and weather and other factors of green shrimp, generally feeding 2-3 times a day, and it is advisable to eat it in about 2 hours.
Water quality management. The quality of water quality directly affects the growth and yield of green shrimp, so water quality management must be strengthened. It is necessary to fill with fresh water regularly to keep the water fresh;Rational use of biological agents to regulate the content of ammonia nitrogen, nitrite and other harmful substances in water;Do a good job of adjusting the water level and maintain a suitable water level.
Day-to-day management. Daily management is one of the key aspects of shrimp farming, and the growth of shrimp should be checked regularly, and the feeding amount and breeding density should be adjusted in timeStrengthen the patrol of the pond, observe the water quality and the activities of the green shrimp, and deal with the problems in timeDo a good job in breeding records, summarize lessons and lessons, and continuously improve the level of breeding technology.
Fishing & Marketing.
The growth rate of green shrimp is relatively fast, and it can reach the market size after 2-3 months of cultivation. The fishing method can be artificial methods such as ground cages and nets, and mechanical methods such as pulling nets and spinning nets can also be used. Preparations should be made before fishing, such as setting up anti-escape nets. The caught green shrimp should be processed and sold in a timely manner to ensure quality and profit.
