Current status, technological innovation and development strategies in shrimp farming of Litopenaeus vannamei in Fujian Province

Background Litopenaeus vannamei was the main variety of shrimp aquaculture in China with delicious meat, fast growth, strong disease resistance and good benefits. It has gradually become an important pillar industries for fishermen to increase their income and become prosperous. Purpose The current situation and technological innovation of shrimp farming were explored to promote the high-quality development of L. vannamei shrimp industry in Fujian. Method The seeding production, breeding mode, breeding yield, technical measures, risk analysis and development strategies of L. vannamei in Fujian had beend systematically analyzed by the relevant data of Fujian shrimp industry from 2014 to 2024, which combined with questionnaire surveys and field investigations. Result The crucial production and distribution hub for L. vannamei shrimp seedlings in Qianting Town, Zhangpu County of Fujian province. In 2024, the total shrimp seedling output of L.vannamei in Fujian Province reached 75.373 billion tails, accounting for 6.62% of the national total.Fujian Province was the main production area of L. vannamei in China. The shrimp farming models were diverse and complete, with obvious distribution areas.The structure and facility configuration of shrimp ponds had been constantly optimized, and the farming output has been gradually increasing. In 2024, the yield per unit area of L. vannamei in Fujian’s marine aquaculture was 14.14×10³ kg/hm², and there was an increase of 79.22% compared to 7.89×10³ kg/hm² in 2014. The farming output of L. vannamei was 261 400 tons, accounting for 11.0% of the national total,and ranking fourth in china in 2024. In recent years, the cultivation technology of L. vannamei has been continuously innovated, forming characteristic cultivation method of large-scale and significantly profitable, such as the “white+black” rotation ecological model, pond engineering aquaculture and shrimp continuous multi aquaculture in ponds. By adopting real-time water quality monitoring, ecological water regulation and intelligent feeding, shrimp farming management has been realized intelligent and ecological, and promoting the high-quality development of L. vannamei. Prospect With the seed industry innovation, technological empowerment, talent cultivation and policy guidance, the practical innovation of L. vannamei would been injected into a new vitality, and promoting the green development of the shrimp industry in Fujian Province.
