陆基圆池循环水养殖条件下饲料添加剂的研究与应用展望

Research and Application Prospects of Feed Additives in Land-Based Circular Tank Recirculating Aquaculture

摘要: 陆基圆池循环水养殖是集约化、可持续的养殖模式。然而，该模式的高密度、封闭式养殖环境对水质管理、鱼类健康及生长性能提出了更高要求，精准营养调控成为保障养殖效益的关键因素。目前，直接针对陆基圆池循环水养殖的饲料添加剂研究仍较有限，但传统集约化养殖系统中的相关研究可为其提供重要参考。本文基于常规高密度养殖系统的现有证据，结合陆基圆池循环水养殖系统的特性，探讨饲料添加剂在该模式下的转化应用潜力。重点探讨了营养代谢促进类、免疫调节与抗应激类及其他功能性添加剂的作用机制，并分析其在陆基圆池循环水养殖环境中可能优化方向。未来需开发适配高密度养殖环境的新型功能性添加剂、优化添加剂的应用策略。

Abstract: Land-based circular tank recirculating aquaculture is an intensive and sustainable farming model. However, the high-density and closed breeding environment of this model puts forward higher requirements for water quality management, fish health and growth performance, making precise nutritional regulation a key factor to ensure aquaculture efficiency. At present, research on feed additives specifically for land-based circular tank recirculating aquaculture is still relatively limited, but relevant studies in traditional intensive aquaculture systems can provide important references for it. Based on existing evidence from conventional high-density aquaculture systems and combined with the characteristics of land-based circular tank recirculating aquaculture systems, this paper explores the potential for translational application of feed additives in this model. It focuses on discussing the mechanisms of action of nutritional metabolism-promoting additives, immunomodulatory and anti-stress additives, and other functional additives, and analyzes their possible optimization directions in the land-based circular tank recirculating aquaculture environment. In the future, it is necessary to develop new functional additives adapted to high-density aquaculture environments and optimize the application strategies of additives.
