Scope

Scope: This document applies to the pond farming of green shrimp; Main technical content: 4. Environmental conditions and facilities equipment 4.1 Environmental conditions: Located near water sources with sufficient water volume and clear water quality, the farming environment shall comply with the provisions of NY/T 5361. The water quality of the water source shall meet the requirements of GB 11607. 4.2 Shrimp pond conditions: The pond should be rectangular, with a length in the east-west direction, solid pond banks with good leakage resistance. The soil should be loam or clay, with a relatively flat pond bottom and silt no deeper than 15cm; the slope of the pond bank should be 1:2 to 1:3, with an area of 1,800–7,000, and a pond depth of 1.2m–1.5m. It should also have complete water intake and drainage systems. The water intake should be filtered with a filter bag made of a sieve with a mesh size of more than 80μm. 4.3 Supporting equipment: Shrimp farming should be equipped with mechanical equipment such as pumps and aerators, with an aerator power of more than 0.2kW per 667m2 of water surface. 5. Preparations before stocking 5.1 Pond cleaning, disinfection, and reinforcement of pond banks: Clean and disinfect the pond, plug leaks, and remove excessive silt. Add water to a depth of 10cm–15cm, and use 80kg–120kg of quicklime (block lime) per 667m2 of water surface; or 6kg–8kg of bleaching powder with 30% active chlorine; or 3kg–5kg of bleaching powder with 60% active chlorine to kill pathogens and pests in the pond. 5.2 Sunning the pond: After disinfection, the pond should be sunned until the pond bottom is completely white, dry, and cracked. This usually requires more than 10 days of sunning. If there are cloudy or rainy days, the sunning time should be extended appropriately. 5.3 Waterweed planting: It is best to choose submerged plants such as Spirodela polyrhizoides for waterweed planting. The waterweed coverage rate should be 25%–60% of the pond
