Efficient culture technology of two crops of Litopenaeus vannamei a year

文章介绍了凡纳滨对虾(Litopenaeus vannamei)池塘养殖关键技术,包括池塘建造、清淤和消毒、苗种选择、淡化标粗、温棚暂养、虾苗投放和养殖管理等。通过温棚暂养,克服了北方地区春季气温较低,不适合养殖凡纳滨对虾的限制,实现了一年两茬养殖。可供北方地区凡纳滨对虾养殖技术人员和养殖专业户在实际生产中作为技术参考。

In this paper,the key techniques of Litopenaeus vannamei pond culture were introduced,including pond construction,dredging and disinfection,seedling selection,desalination of standard size,temporary cultivation in warm shed,shrimp seeding and culture management,etc.Through the temporary cultivation of warm shed,we overcame the limitation of low spring temperature in the northern region,which was not suitable for the cultivation of Litopenaeus vannamei,and realized the cultivation of two crops a year.It can be used as technical reference for Litopenaeus vannamei culture technicians and professional farmers in the northern area.
