Review on Litopenaeus vannamei recirculating aquaculture technology: basic equipment, influencing factors, emerging technology, and sustainability
摘要
Litopenaeus vannamei is the world’s most farmed shrimp species and occupies a significant position in the global aquaculture industry. Industrial recirculating aquaculture has the advantages of being green, high-yielding, and controllable, and it is an important direction for the development of the L. vannamei aquaculture industry. In recirculating aquaculture systems (RASs), the removal of pollutants and the optimization of the water environment are key to the successful aquaculture of L. vannamei. As a high-energy-consumption aquaculture technology, energy saving and emission reduction are the keys to the future development and promotion of RAS. This paper introduces the main equipment of RAS and the main influencing factors of L. vannamei aquaculture. It discusses the application of electrocoagulation, membrane technology, advanced oxidation, and bio-electrochemical technology during the aquaculture of L. vannamei. Moreover, it explores energy saving and emission reduction in RAS from the aspects of new energy, frequency conversion control technology, high-efficiency oxygenation, and aquaculture waste resource utilization. The purpose of this paper is to promote the application of RAS in the culture of L. vannamei, stimulate innovation, and improve the process performance and future application of RAS.
